|OK with fat32 in c: you have a couple of routes that may get you back in...|
If it was ntfs then you are slightly limited in your options; you would need to invoke (even install) the recovery console routes, or get in via safe-mode; or - run a repair installation routine. I think in your situation (where c: = fat32) you will be well able to avoid a repair installation; will be able to either edit the boot.ini or regain access via the safe-mode/recovery console.
So - boot with a '98 bootdisk, change to the c: drive, locate the boot.ini, copy it to a floppy (and lock it); then edit the version on the c: drive using the edit util on the '98 bootdisk. You would copy (most of) the line for W2K that works to the default OS to boot position (at the top of the boot.ini). At the least see if you can copy it to a floppy and post it here, and it may help simplify a resolution for you?
Essentially your boot.ini would (should) resemble (when all things are OK):
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect
(Note that entry for default OS to boot is shortend version of that same entry present within the main body of the boob.ini)
There would also be line referring to the incomplete installation. At present that has set itself as default OS to boot (standard procedure during an installation) and it may also be that you previously set your time to boot to zero (the default is 30seconds...) If you did set time to boot to zero that's one reason you can't access start-up options.
With that in mind you could boot up as per norm and press F8 during normal boot-sequence so as to gain access to W2K start-up options. These will/should include safe-mode and in that mode you should be able go into Explorer and gain access to the boot.ini (as detaield in an earlier post). Open it via notepad/wordpad and make the changes described just above. (There are how to edit the boot.ini instructions also in the links that "Chuck2" regularly posts here - see my earlier post above.) You will need to logon as the Administrator when using safe-mode.
What you are attempting to do is to set the working version as default OS to boot - and to reset time to boot to at least 10seconds (you can do this whilst editing the boot.ini too, just change to time to boot=0 to =10). Save changes and exit; reboot and you may then boot to working version, via the boot-menu displayed for 10seconds...?
If you installed the recovery console in earlier times then that should also be an option in the start-up list (following F8). If it is there invoke/use that to gain access to the installed version. You will/should be able to select the working version and boot to it. Once in OK set it as default OS to boot (MyComputer\Advanced-tab\start-up/shutdown button) - and then reboot to verify it does just that. Presuming so - MAKE an ERD and keep it handy. Afterwhich you simply locate and delete the folders/files related to failed installation. Typically it will not be winnt; it may have a $ symbol at its start, and there may (will) be other folders/files that start with $ symbol. All of these can be safely deleted. Then access the boot.ini and edit out the refereces to the unwanted/failed installation. Reboot to verify working version is (still) OK; presuming so empty recyle-bin and defrag the drive (to clean up the scene). RENEW the ERD; lock the floppy and keep it safe.
If no recovery console alrady installed that too can be installed quite simply.
Perhaps initially access the boot.ini (via a '98 bootdisk boot), post it here, and save it to floppy as well. Then "we" can clarify what it should look like so that you can edit it accordingly. Afterwhich you should be able get back in and able clear away the the remaining junk/mess etc...
Ideally you should have had an ERD that was valid prior to the failed installation; also perhaps have had the recovery console installed - or at least be familiar with houw to add it to a system that won't boot to a working OS... Either would have allowed you back in rather easily... But then one learns from one's mistakes/diasasters etc.; and frequently even the Pros fail to have a valid ERD around when needed...
Note that on many (all?) '98 bootdisks the edit util is in a cab-folder and has to be extracted... You may not feel happy doing this although it's relatively easy... As obviously you have access to another PC you could make another copy of the boot.ini (from your non-working PC) to another floppy and edit that copy on another (working) PC. Then copy that edited version back to the floppy and thence to c: drive (on your non-working PC) - i.e. replace/overwrite the version already there. Then boot as normal etc. (no '98 bootdisk) and hopefully you come up in the version you want again?
Any of the above routes would/should get you going again; just read them thru and see which appeals to you; some are less involved than others?
And again perhaps initially post the boot.ini here before you start to edit it - unless you feel OK about it and can acces it either via the '98 bootdisk or a safe-mode or recovery-console access?
This labmice page also has lots of useful info for the future:
It's just one of many excellent resource sites to know about...
I'm really trying to give you an idea of the some the various ways you can get back into a system When it's fat32 you have more options than when it's ntfs. Also with fat32 you can usually gain access to data folders/files and get them off the system before geting into serious recovery routines (not necessary in your present situation).
