Solved Multiboot with 2 HDDs: How Bootloaders Interacts?

December 14, 2020 at 20:33:06
Specs: Windows 3.1(x16) on FreeDOS(x32)+Windows NT 5.2(x64)+Windows NT 6(x64)+Windows NT 7(x64)., 2.6 to 3.5GHz/10GB.
Greetings,i already successfully installed many multiboot systems,but all was single-HDD multiboots,i had only 1 with 2 HDDs long ago via BootMagic,which i think is too old to be used up to Windows 7(it was in my old desktop,it had Windows 98 SE & Windows XP on primary HDD & Windows 95 on secondary HDD in removable rack & it was all IDE),now i plan add another 4 OSs to the 2nd HDD in hot-swap module 2nd HDD caddy of my Fujitsu Lifebook P772 laptop,the module r planned to be swapped with ODD module,the more used OSs r on primary HDD,the less used OSs i would like to install to the secondary HDD,both HDDs r SATA3 WD20SPZX(2TB),both MBR style,both with 4 primary partitions.
I will use external DVD drive for installing the OSs to the sec.HDD,which will be at the time in the place of the internal DVD drive,i need to know,will the BOOTMGR &/or Boot.ini on primary HDD be affected by installing OSs to the secondary HDD?
Should i disconnect the primary HDD during installations to the secondary HDD?
R bootloaders separate for each HDD,or OS installed to HDD1 will overwrite the bootloader(s) on HDD0?
Thanx in advance for answer.
Happy Chanukah for those,who celebrates it these days.

"Should i disconnect the primary HDD during installations to the secondary HDD?"
Yes.

"R bootloaders separate for each HDD,or OS installed to HDD1 will overwrite the bootloader(s) on HDD0?"
Because of the complexity of what you are doing, you will be best using Google, to research each step.

You need to set the priority hard drive to BIOS.

Thanx 4 advices.In meantime i found this:
https://www.tenforums.com/installat...
The article states,that if both HDD will be present,when i will install OSs to the secondary HDD,bootloader(s) will be merged & disk 1 will have no bootloader & the bootloader of disk 0 will be edited,which i must avoid,as on the HDD0(primary HDD) i have newer OSs,than i plan to install to HDD1(secondary HDD) & also i plan to install beta builds to HDD1, 2 Windows Longhorn pre reset builds(other 2 planned OSs on secondary HDD r Windows Server 2003 & 2008,both 32bit Enterprise editions),so these r definitely OSs,which must not mess up the bootloader on HDD0,as there is Vista & 7,all managed by Windows 7's bootloader,which has also a menu item "Earlier Version of Windows",which loads the old Boot.ini bootloader for Windows NT 5.2 & Windows 3.1).By that article there is even danger,the installation of OSs to secondary HDD may move all boot files to secondary HDD making the primary HDD unbootable without presence of the secondary HDD,sure it overwrites current boot files & also may move them to a HDD in hot-swap 2nd HDD Caddy module,which would make impossible to boot from primary HDD,if i will have back the ODD(swappable with secondary HDD).
Also there was wrote,if i always have connected only the target HDD during OS installation,both HDDs will be independent on each other & will have separate bootloaders,which is the goal.
Fujitsu Lifebook P772 has very friendly BIOS & it also has shortcut to bootmenu by F12,so no need to enter BIOS each time,i need to boot from another HDD,just press F12 & select boot device,so separate bootloaders would be ideal,i could let the priority for HDD0 & when need booting from HDD1,select it via BIOS Boot Menu & then the particular OS from particular HDD's bootloader,if i will select priority for HDD1,it will be the default boot device,if present,if not present,skipped to boot from HDD0,for any of this arrangement according to that article & Johnw,i sure must disconnect the HDD0,when installing OSs to HDD1.
If i will just set priority for HDD1 & let HDD0 connected,when i will install OSs to HDD1,if i understood everything right,i risk not only messing up current bootloaders on HDD0,but with priority set for HDD1,the OS,which will install,will probably think,HDD1 is HDD0 & vice versa & may move bootloaders to the HDD intended to be removable[HDD1(cn as HDD0 in these conditions)],so i c,i must really disconnect HDD0 to absolutely ensure,its bootloaders will not be changed,nor moved,Johnw is right about the complexity,i am about to create multilayer multiboot(multi-multiboot):
-BIOS Boot Menu:
--ODD1.
--ODD0.
--USB.
--HDD0-BOOTMGR:
---Earlier Version of Windows-Boot.ini :
----Windows 3.1 (16bit) on FreeDOS(32bit).
----Windows NT 5.2-XP Professional x64 Edition(64bit).
---Windows Vista Enterprise(64bit).
---Windows 7 Enterprise(64bit).
--HDD1-BOOTMGR/Boot.ini(i do not know,what bootloader is used by Windows Longhorn PRE-RESET builds):
---Windows Server 2003 Enterprise(32bit).
---Windows Server 2008 Enterprise(32bit).
---First build of Windows Longhorn-Pre-Reset(64bit).
---Last build of Windows Longhorn-PRE-Reset(64bit).
So,this is 3-level depth multi-multi-multiboot(the part on HDD0 done,the part on HDD1 intended).
Credit: Windows 3.1 & Longhorn installers r from WinWorldPC.com (terrible admins' behavior-extremely rude & invective,but impressive database of abandonware).
CREDIT: FreeDOS,i have,is from Rufus & the author of Rufus also helped me with configuration a little.
If U guess,i have so many Enterprise versions,yes it is also,because i am Star Trek fan,but this is secondary reason,the primary reasons r:
-Enterprise versions of Windows 6(Vista) & 7 accept MBR disks(yes,64bit versions on UEFI too),thus i can combine them with older OSs on same disk,other editions of 64bit Windows 6 & 7 refusing to be installed on MBR disk.
-Windows Server 32bit Enterprise editions can allocate RAM over 4GB,thus i can run almost unlimited amounts of 16bit & 32bit programs simultaneously.My 16bit screenmates will sure become agoraphobic on 10GB RAM(yes,if U want to do something hungry of RAM,but have a 16bit screensaver with trains & 16bit Sheeps accessible in same time,U need Windows Server 32bit Enterprise).
-Yes,U r right,if U think,i can also use the Datacenter edition,but i have that secondary reason,i am Star Trek fan & Enterprise sounds & looks(on logon screens,in Boot Menu,in Camputer->Properties...) much better,than Datacenter.
If this will success,it maybe will be the most complicated multiboot ever & it is very probably the 1st system ever,where 16bit apps will have access to 10GB of RAM(i guess,no1 installed retro-apps in real servers) & sure this is 1st occurance of installing Windows Server OS because of running a lot of 16bit apps simultaneously,of course due to closed museums i will maybe have never the opportunity to run this in museum & display it on a large screen full of very old apps running simultaneously,but if museums will be opened somewhen...i will go there with this laptop & show the beautiful 16bit apps to public,from which 75% of people r unaware,there was a 16bit era & 99% unaware,it was beautiful.This is the reason,i put all historic SW into laptops,i can take a laptop & project this in any museum,where personnel is interested to SW history,as i have no car,it would be difficult,if my collections would be in desktops.
Thank U & this forum,i already created amazing historic SW projects...
...i shall mention Computing.net for its help in my Autoexec.bat files,Your helpfulness deserves an ECHO.

Chag Chanukah Sameach.

U r welcome & thanx,but i have only half done of this project(4 OSs on HDD0),but U helped me to ensure avoid damage of that half of my work,i have already done,when i will do the other half(HDD1).
Now i must determine,is my 2nd HDD caddy module a passive or active adapter,the producer did not answered me,has it AF sector translation or not,if it has no translation,i can place the HDD1 temporarily in place of HDD0 & install the OSs via internal ODD,but if the caddy has sector translation,i must install OSs with HDD1 already in the caddy,as if i would did that connected directly,then place to the caddy,the sector translation will make partitions invalid & in this case i must use external ODD.
Did U cn a manufacturer,who r unable to answer the question,"has your product AF sector translation or not"?

Just for info, there is not really such a thing as abandonware, in as much as it always remains the property of the owner. It's just that they don't bother to go out of their way to protect it.

Always pop back and let us know the outcome - thanks

Greetings/Shalom,Mr.Derek,yes this is the precious definition of abandonware,the owner no longer bother to legally protect it-no longer goes after users,who installed it,by the WinWorldPC.com Microsoft is not interested in anything older,than Windows NT 5.1 XP,U will find this on their article about Windows NT 5.1(Whistler/XP),beginning with Windows XP Microsoft protects the final releases,but not the alpha,nor beta builds,so for sure i use the beta builds,or OEM bought with a computer,in example my Vista is build 6000-the final beta,but still beta.WinWorld stated,that Microsoft asked them to not share any final builds newer than NT 5.1(including it),but U will find there all,but final,builds of Whistler,Longhorn,etc & of course everything up to NT 5.0 including final builds & Microsoft is aware of it.
& of course,1 thing is,the owner/author/producer may decide,which She/he/ze/it consider abandonware,other thing is the approach of local governments,in some states even abandonware abandoned by its creator/owner same way,as Microsoft stated,which versions it abandoned & which not,a state may go after users,who installed abandonware of this type,by itself-without a request of the owner,these r states,which declines the term abandonware & it do not exist by law in this states & yes,i exchanged few mails with a German about Windows 3.1 on FreeDOS on Live USB Flash Drive(my other project) & he said,Germany does not recognizes in its laws the term abandonware & users of it may be charged same way,as if they illegally installed or shared something brand new,regardless the owner wants or not,the users r intercepted & fined,so yes,there r countries,in which legally abandonware does not exist & the only difference between abandonware & latest commercial SW is,in case of abandonware U will stand against the government @ the trial,not against the owner & the owner even may not be informed & may not get a part of your fine & all the fine goes to the government.I guess,this is same in UK & US,as i was informed about Deutschland/Germany.
On the other side there r countries of opposite extreme,where abandonware is considered freeware,thus is absolutely legal,in these countries U also may say,abandonware do not legally exist,as it is legally marked as freeware & has no own category.
Than there r many countries in between,where abandonware is legal term & definitely exist,as it may be i.e.considered freeware only after a minimal age of the product is reached,or if the owner apparently has no interest in it.
In Czechia abandonware is specified as SW,which owner no longer interests in it & applies no requirements about the SW law-protection,i am not sure,is there also an age limit.Of course this applies,if u continue to share such SW only for free,if U will try to use abandonware for commercial use/ask money for it,U will be in pretty different law-position(worse),i.e.,even if i creating the museum of abandonware,the law-border for me is,i cannot ask money for entering into such museum,nor for borrowing the abandonware to a public museum or exhibition,in many cases this applies also for some freeware,which was always freeware since its creation,as many freeware has limit "only for non-commercial use",so when U ask money for sharing it or something created with it,U breaking the law,as for freeware this must be stated in product license or documentation,if the product is abandonware,this is automatically applied,so there r differences between law approach to freeware & abandonware in some countries,but if U using abandonware here for non-commercial purposes,U may not be scared of cops,just not try to sell the abandonware,gift it is OK & in case of Windows newer than NT 5.0 do not forget to choose the alpha or beta builds(no,U cannot buy it,as it is EOL & Microsoft no longer sells it,unless U buying an old machine,which has it as OEM).
Than the separate & most complicated is international sharing of abandonware,i.e.if i have 1 citizenship,the receiving person has another citizenship & we meet in a 3rd country(none of which citizenship i & the other person has),the laws of all 3 countries may apply & the process will be very complicated,if these laws r contradictive,better count with the worst laws of all.This applies,if a SWAT will arrest us right @ the meeting with Flash drive in hands,be4 & after meeting only the laws of each citizenship & the country,i am in currently,may apply,not the laws of the other 1 person's citizenship,if it is be4 or after meeting,mostly the laws of the country,i am currently in counts as main,but even if i will give abandonware via internet to some1,who is a citizen of &/or is in the country,which never consider abandonware as freeware,they may then go after me too as my crime may be giving Windows 3.1 to a person,who has no right to receive it because of laws of her/his/zer country or if some1 will give me Commander Keen 3(missing this),who is a citizen of a country,where it is forbidden & has no right to give mi it,i may be arrested too.
& also if somewhen local government changes its opinion,i may lose everything,if i.e.the government decides,that from now,all abandonware,freeware,orphanware,etc.is illegal,all,what yesterday was legal & cops starts to search for it in every apartment...
...A year ago i could not imagine,1ce the government will decide,what was yesterday an essential human right,from today is banned & fined,as leaving home without a Dog after 21:00,so if they could ban freedom of movement,even it was an essential human right less than a year ago,they sure may also ban abandonware,freeware & orphanware from day to day,they may even ban computers at all,government can ban anything & everything anytime,any government,Yours may tomorrow allow abandonware,my may tomorrow ban it,governments proved,they do anything anytime to any1,because they can,thus it is good to have a mobile home(not so lucky) & with each worsening of local laws move elsewhere,so U must also have a job applicable everywhere to be ready to flee,when local governments goes mad,or more mad,it currently is.
Here museums r banned yet,so any visitor means fines to both,the visitor & me,no matter,he/she/ze would not pay anything.
I hope,governments will always have more lucrative interests,than go after abandonware collectors,who does not use it for commercial use & hope,Your government will not ban conserving old streetcars & my will not ban conserving of old SW(nor streetcars),but i am also afraid,they may ban anything anytime,now 99.9% of world governments proved their totalitarian nature,so it is in fact a miracle,in a country,where U may be punished for walking,U will be not yet punished for playing DOS games,nor exploring Windows Longhorn Pre-Reset beta builds & as i have no money for moving to 1 of very few democratic countries left,i must obtain a poison to be ready,when government will ban everything,i love,the suicide will the only option left,when cops will be attacking my house,better than go to prison & speak with a cellmate:
-For what U r here?
-I killed my entire family & U?
-I just did not erased my HDDs,when government banned abandonware.
-So u will be punished much more harder...What abandonware U had?
-Windows 3.1...& many more...
-U fool,do U know,16bit SW is the hardest contraband...from yesterday...12hrs ago government decided to reestablish death penalty & having 16bit SW is 1st on the list of death crimes,6hrs ago they decided,they will execute computer criminals on electric chair,i hope,the Sheep was not your favorite app?
-Yes,it was.
-So u r lost,they will fry u slowly...
...
Yes,this may happen,if they already turned former democratic states upside down,u may await anything,so now it is legal here,but few months ago also night-walking was legal,tomorrow even breathing may be illegal(did U cn Total Recall?),local government changes laws more often,than their socks.
Mean time between law-changing is now about a week,miss 1 statement of the government & u risk fines,the cop will say:"U did not know,yesterday government changed the times for beginning & ending the ban of leaving home?Your problem,U was lazy to watch the government's website daily,u will give me 20'000,/CZK & that,your pension is only 13'000,is your problem,u did not watched the government's web,die by hunger,better,that die by covid..."
I think,the government's strategy is making the changes of laws more & more often,thus no1 will be able to watch it & be up to date with recent bans & u will get fines larger than your property,thus u will lost everything & be sentenced to work in a plant for the rest of Your fine,but as u will have no money for mask(with old confiscated with all property),u will be fined daily fined again & will never leave the plant,i think,this is the final plan of the government,transform all citizens to Foxconn(or other plant) slaves & they will probably skip the arresting for abandonware,as it is much more comfortable for the government to ruin u by fines for forgetting the mask or the hour,u must return home,now the government has so many ways to destroy citizens by corona-laws,it is absolutely redundant to care about abandonware & even there is no free cops,all r fining people for corona-laws breaking,no free cops to search over your offline computers/partitions for abandonware,even capacity of bureaus is not infinite,with so many sentences over night-walkers & people without mask there is no time for additional trials against home-SW-museums(even tomorrow they would ban abandonware).
Enjoy Chanukah,till it is not forbidden again(it is also a thing,which was forbidden for few years,also banned from day to day).
Enjoy internet,enjoy electricity,enjoy everything,which is not yet banned.
Enjoy the freedom of speach,it is sure on the top of the list of what governments planning to ban.
Enjoy the oxygen...till...Total Recall...
& of course enjoy all version of Windows from 1.0 to 8.1,till all will be banned everywhere,because the only way to make Windows 10 the best is destruction of all its predecessors,mainly Windows 7,still most popular & by most of users the best of all Windows ever...just do the same things on 2 computers with same HW,1 with Windows 7,& 1 with Windows 10 & have Task Manager opened on both & watch the processes sorted by CPU load or simply the CPU graphs...until Windows 7 exists,Microsoft cannot tell U,it is natural & normal,an idle computer uses 89% of its dual or even quad core CPU,in fact over 3 cores for Windows 10,less than 1 core for U,Windows 7 has such load,only if U decide to participate on SETI program...
...which is meaningless,just imagine,Aliens will land & right after fined for wrong parking,not flying preciously by human flight control instructions,being outside & night,crossing borders without valid visa,having no masks(helmets does not count),having unreadable registry sign on their ship,their warp coils not fitting RoHC,nor any ISO & of course their computers running a freeware,as they have no capitalism,so all their SW is freeware,making too much noise,when landing,etc.,etc...& they will be sentenced to free delivery of all of the resources of their homeworld,or maybe their homeworld will be confiscated by humans for not paying fines &/or paying it by replicated money,as they have no other,so who would like to visit Earth?
Even they would not suffer bureaucracy mentioned above,they would suffer billions of refugee requests...like my...with a reason(among others),i want to save abandonware by storing it outside Earth,where it will never be forbidden.

"this is the precious definition of abandonware,the owner no longer bother to legally protect it-no longer goes after users,who installed it"

Microsoft wouldn't agree. And WinWorld exists only because it's likely well hidden away from tracing.

So they(WinWorld) just lied,Microsoft only asked them to remove final versions of Windows NT 5.1 & newer?
Would not be surprised,as the admins' behavior there is the most rude & invective,i ever encountered(speaking about admins,not about users),they r the precious opposite of Admins here,by the behavior,they r Your Mirror Universe,so y they should behave better to Microsoft,than to old-SW collectors,so cannot deny Your statement,but they play this very well("everyone,who will request Windows XP or later will be immediately banned"),so this border is just their fantasy & in fact Microsoft will go after all technical museums worldwide,till they will destroy the last 16bit Windows copy?
But as Microsoft does not provide any way to legalize any EOL version of Windows,the result is,any museum projects r outlawed & the goal is,anything EOL should be totally out of existence?!
Little like Farenheit or Equilibrium,but with banned museums @ all it sounds very realistic,it is very sad,the protecting of rare historical values is illegal @ all,an effort to destroy all EOL SW is a cultural barbarism & i hope,all the collectors & museums worldwide cannot be arrested/destroyed,i hope,somewhere a copy will survive & recollected...until the creator,who wants to kill all of its children,will die...& thus any protector of old SW sentenced to be totally deleted,is a Silicon Hero,thank U all others,who risking to protect historical values,i do not c any difference between this & that,what Derek did for protecting another historical values-old streetcars,or what others do in railroad museums,preserving old good things,i appreciate every1,who perform such actions for any historical values,Derek risked & probably damaged his spine,when he helped to fix valuable historical streetcars(i also helped in transportation museums & my spine is in such condition,i cannot continue),i maybe risking death by hunger,if Microsoft will finnancialy destroy me for preserving old versions of Windows,WHICH CANNOT BE LEGALIZED,very little historical values would be preserved without any risk,thank U all,who doing such risk & helping to preserve anything.Historians had born as historians,a historian cannot stop to be a historian,if some1 bans the history...Orwell guessed so well...
...so just add an another reason to proper & multiple backups for all historians,but for now,as here we has Pirate Party as 1 of the most successful in every elections,i hope,my 16bit pets r safe for now,but no1 knows,for how long the "now" may be valid,so i guess,i should have anything EOL disconnected from internet to not be destroyed by Microsoft,am i right?
Which means,i will have to install Windows 8.1 or Linux to 1 partition on any machine,i accessing internet from it.
For example this laptop left the plant with Windows 7 Professional,i even do not know,was it 32 or 64bit,but i needed a version,which can access 10GB of RAM & install on MBR disk,which is combined only in Enterprise Edition,but how can i legally upgrade from Windows 7 Professional to Windows 7 Enterprise with any edition of Windows 7 with EOL(=no longer available from MS itself) status?
I have the serial for the Windows 7 Professional on the bottom of my laptop,but that will not install on MBR disk(64bit version),so i used that information(probably a lie according to T-R-A),WinWorld stated,Microsoft requested removal of only final versions of Windows 5.1 & newer,so i installed a beta build hoping it as legal workaround,until i will not sell this copy to others,local government will ignore it,what i am afraid,is Microsoft's remote access destroy tool,i heard,is used to destroy such installs.
Interesting is,in other bussines it is normal to sell older products for discount price,when the newer products starts to be selled,but Microsoft instead just bans all old versions...so it forces collectors to use an activator instead of buying,as it is no longer available,even if some collectors r rich enough to buy even Windows 1.0 for full price,it is not possible...i bought,what i could buy,i activated,what i could not buy,as most of collectors,i have even an original package of Windows 3.1,but that is Czech version & i wanted to have the original-English version,so i downloaded it from WinWorld,what i could do else?
Just download it from Ulozto.cz or from other such web,i could not download it from Microsoft.
Derek also cannot buy a 100-years old streetcar from its original manufacturer,even if the manufacturer still exists...
I originally hoped,i will use the Downgrade license for obtaining old versions of Windows legally,but now U can only obtain Windows 8.1 this way,which U can also buy directly from MS,but U cannot buy,nor downgrade to Windows 7 or older.I searched more legal ways,but i did not found anything else & if it is selled by a 3rd party,it may be illegal too.
So thanx for information,i may be intercepted by Microsoft even for versions,WinWorld stated,MS no longer cares for.
Best regards.

UPDATE:
Greetings to all,i was offline,because i worked on my historical OS projects,if some1 is also interested in this particular project focused on Longhorn(the other parts of my 8-OS multiboot r easier & U will be able to do it so without a more detailed data,U just must use Enterprise editions of Windows 6 & 7 to be able to install them on same disk with NT 5.1/5.2 OSs,as Enterprise editions accepts MBR disks).
Beside Windows Server 2003;2008;XP;Vista;& 7,which is easy,i focused on Longhorn on my newest & strongest machine & if U also want to explore this particular part of IT history,i advise U to do so-use Your strongest computer for Longhorn,even with 2 physical/4 logical core-CPU @ 2.6GHz Longhorn builds,i was able to successfully install,requires about 20 mins to boot & behaves little lazy,so i wonder,how it even could run 13 years ago,when such strong computers was just a dream,i assume,it was compiled & tested on servers of that era,because personal computers of that era had single-core CPUs @ 1.6GHz for the most high-end computers,so it barely could run on laptops in 2003 to 2006,when it was developed,so if U r interested in Longhorn,definitely do not use a computer matching its era,unless it is a server machine of that era,if U have complete CSM,it will accept a UEFI computer,but do not forget enable CSM,disable Fast Boot & Secure Boot & ENABLE IDE/COMPATIBLE MODE FOR SATA.
I was interested in pre-reset builds,so this all is about pre-reset builds of Windows Longhorn(last preserved build is 4093)(downloaded from WinWorldPC.com):
These builds(all Pre-Reset) uses NT 5.1/5.2 bootloader,so DO NOT INSTALL THEM ON A DISK ALREADY CONTAINING A NEWER OS WITH NEWER BOOTLOADER INCLUDING VISTA & PROBABLY THE POST-RESET LONGHORN BUILDS,these builds can be installed after or be4 another NT 5.1/5.2 Windows,but only be4 NT6+ builds.
Even marked as version "6.0",it has 5.2 kernel or some its modification & the architecture & GUI r much closer to Windows XP/Server 2003,than Vista & onwards,drivers & activators for XP/2003 will work & they will think,it is an unknown build of NT 5.1/5.2,NT6+(Vista+) drivers mostly does not work on Longhorn Pre-Reset,so technically Longhorn Pre-Reset is really not a Windows NT 6.0,but a range from NT 5.3 to NT 5.9,the core behavior & structure is NT5-based,except the displayed version it has nothing common with NT 6.0,as U can assume from Pre-Reset builds,the development reset is the real time-border between NT5 & NT6 era,so be sure,when U bother with Pre-Reset Longhorn builds,U r still in NT5 era & U r looking @ a modified XP,not @ a proto-Vista,almost anything,U remember from Your XP,U can apply on Pre-Reset Longhorn,but U will need to do something else,when Longhorn is booting,go with Your Dog for example(a standard,not a shortened walk)...& sure do not run Longhorn on battery power,i assume,the boot would drain the whole battery(i mean new & healthy battery)(if U have an island-system Photovoltaic power plant-powered house,do not run Longhorn @ night:)...unless U have a wind-generator too).
Do not let Your laptop run Longhorn on a place with poor cooling,for example in bed,it will really need a proper cooling...good for long winter nights...when U will go back from the walk with Your Dog,U can put Your frozen hands near to the CPU cooling output...probably it will still be booting...no,it is not frozen,when U c a black screen for 10 mins...it is just booting,U will understand well,y its development was reset.
Some builds has XP Installer,some has a new installer,but all these builds has old-fashioned XP-style bootloader.
If U will install more builds,all entries in Boot.ini will be "Microsoft Windows Longhorn" without build numbers,U will need to add build numbers into Boot.ini to distinguish builds.
For Jews:Yes,using Longhorn will take U more time,than using Shofar in entire Elul & Tishrei combined...& Your CPU fan will be same noisy...U can count it as U had fulfilled the obligation to hear a Shofar blast...:) .
IMPORTANT ADVICE:
Some of Longhorn builds will mess up Your Boot.ini as a part of installation failure,it is good idea to not install it on Your primary HDD,dedicate an another HDD for this.
As these builds r extremely resource-hungry,i do not expect a good behavior in VirtualBox or other virtual environment,if U have large RAM,it is not a problem,Longhorn can use only 4GB of RAM,but it really needs entire power of Your CPU,i did not tried,but i assume,sharing CPU with the host OS will have terrible influence on both-Longhorn & a host OS,as it really uses 100% of Your CPU,it is good to install it directly on the real HW & give it whole CPU power.
Installation process is same or very similar as the installation of a normal NT 5.1/5.2 OS.
PARTICULAR BUILDS TESTED:
I was unable to install any of 4 64bit builds available,it crashes or freezes,when installer switches to 64bit mode.
It is all marked "AMD",so probably these builds r only for AMD processors & r incompatible with Intel processor in 64bit mode,who has an AMD machine,can try it & maybe share the results.
I have only Intel CPUs,there builds did not worked with my Intel processors.
x86 BUILDS:
I was able to install successfully only builds 4042 & 4029.
Other builds failed in various states of install attempts.
Builds 3??? messed up Boot.ini .
Build 4008 installed,but has 2 or more autodestruct mechanisms included,my activators solved 1 of it,it showed,it is activated,but also showed a Window "Evaluation period expired...system will shut down in 1 hr...",but this is not that known from Windows 6;7;8 & 10,which shuts down the computer,but lets U boot again & gives U another hour for activation attempts.
This particular version in Longhorn 4008 kills the OS for ever,it not only shut down the machine,but it also fatally damages some system files & the intended corruption is so large,build 4008 will not boot even into Safe Mode,it will be dead forever,any boot attempt,even Safe Mode with Command Prompt will end in BSOD & restart(so quick,U cannot read anything from the BSOD,it is shown for about a 100ms,maybe less).
Builds 4042 & 4029 will be successfully installed,but will not let U to log in.
U must boot both into Safe Mode 1st & use an activator for XP/2003 working in Safe Mode(i found such on Ulozto.cz),it is named AntiWPA*...something,just search for "Windows XP activator",most of them worx with Longhorn Pre-Reset.Or if U r living in a country,where U would be jailed for downloading/using such activator,use these builds in Safe Mode,but in Safe Mode U will not c the Plex & Slate GUI themes,after activation in Safe Mode 4042(Slate) & 4029(Plex) will be able to boot normally,but this takes 20 mins on Intel Core i5 vPro CPU,so after hitting Enter in Boot menu,just go a standard walk with Your Dog,or go to the kitchen to prepare Your food & coffee,i mean hot food,not a bag of Chips,in this case U will need about 5 bags of chips for the booting period & U will be able to drink 2 coffee cups...
But the boot is not so long,U can c a whole episode of Star Trek on another computer during this time,U will need to pause it in half...
For Derek & Trvlr: Do not boot Longhorn during a travelling,U will have serious problems,when U will approach the destination station/stop...
Sad is,the Plex in 4029 is not so nice as in the 4008,difference is in the bookmark-type buttons,these in 4008 have nicer shape,the 4029 version is same as Luna in shape.
If U love to edit Windows colors,forget it in Slate,it ignores all color changes,all colors,U will edit on Slate in 4042,will be reverted after restart,in this version if U want another color theme,U must switch to Windows Classic,in this mode color changes r remembered.
Good luck.
Write,if U want more info.
Thanx again about multiboot info,when i installed this on HDD1 with disconnected HDD0,nothing was altered on HDD0 & both HDD has independent bootloaders,which i switch by F12 BIOS Boot Menu @ startup.
