|I guess boot disks are good to make in case the boot sector gets corrupted - I have looked on the MS site how to make one with the xp cd - |
I suppose I dont quite get the concept of it totally from what I've gathered the boot sector is on the harddrive in a different partition and then theres also what drivers windows boots for the os etc and video drivers and network drivers etc etc a rootkit hides in the bootsector (rootkit is probably bad it is a name for a virus in other words) so if this gets corrupted I would not want to boot from the boot sector on the hd I would want to boot from the boot sector from a floppy or cd or dvd
so I would want to make a boot sector that has all the drivers and etc not just the default ones -
for example if I am confident the boot sector I now have is good I want to make a back up of that soon -
question - and I know these are probably been asked - however maybe this will be usefully explained for me and others - also with external hdd enclosures now and new software there maybe better ways to handle such questions
1 - can I copy the existing boot sector exactly like is onto a bootable drive and use that so all my devices will be bootable not just the default ones [via taking the OS hdd and putting it into and ext enclosure to another pc and copying that sector onto a floppy or cd/dvd)?
2 - once that is copied wouldnt it be easy to reformat the boot sector and reinstall a good copy of it once its reformatted?
3 - can viruses survive a reformat?
4 - is there a way to disable writing to a boot sector partition only? and help prevent infecting such infections and re-enabling writing to it [if new devices are to be installed later and then re disabling writing or enabling write protection, but just to that sector]
5 - besides the above possiblities - if doing the more traditional boot disk copy is there a way to make it so it has all the drivers and everything needed to boot all the devices installed and not just preselect ones and a way to modify it so if more hard/software is added later
6 - also besides the hardrive including boot sector - bios - cmos is there anything else that can be corrupted via viruses trojans and worms? ie memory sticks or anything else like video cards etc??
7 - I do know that bios is generally not often corrupted but I am sure there will be something that does sometime and I want to be prepared for it and also dealing with traditional viruses are alot easier (and I am not really concerned with those too much anywho) than the ones that can get into boot sectors and bios so any ideas on write protecting bios besides getting a motherboard that has those capabilities would be cool to discuss here also
I personally have a few pcs - one has a custom sata switch (on off on) want to make sure if one hdd gets infected it doesnt corrupt the other - even though the other is completely off - through the vid card, memory or bios etc but also that is not the limit of this discussion - there are 7 questions up there and some might be usefull to others and me and I personally would think it should be possible to clone the boot sector via ext hdd encl with another pc - so I hope this actually brings on a lot of discussion and brainstorming for things I have even yet to consider - so please if this interests you let me read your thoughts here
