Reading thru this thread it becomes obvious that no-one seems to do a system state backup. Ever. Not bragging here, just a bit of guidance:
I have a partition which is my Data Store; one folder in it is labelled System State Backup. What is in it? Well, you start Microsoft's Backup [in Pro it is there already, in Home you must load it especially from your installation CD] and it is found under Pgms > Accessories> System Tools.
I put a check against System State, browse to my SS Backup folder [the tool fights a bit, for some reason it wants to put nearly 400Mb onto a floppy set, but that's M$ for you...], and back it up. Takes less than 2mins, including verification. A comfy security blanket. It also updates the files in Windows\repair to your currrent state [default, SAM, SECURITY, software, system...].
Somewhere in this forum I have laid out this procedure of replacing those files in your system32\config folder, plus then using the files in your last successful sysem restore point to get back right to that last good configuration before your troubles began.
Note also that those five files are rewritten in system32\config every time you shutdown your sys [or should be], but NOT in Windows\repair. It does not matter that the ones in \repair are slightly out of date because in the end you would copy them from your latest good system restore point.

hey gerbil,
thx for ur reply but my problem is I am not able to copy the files in repair folder to the config folder thru' recovery console. It always says "the files could not be copied"..... what shud' I do? And what causes this problem that simple files are not being allowed to be copied from one folder to another?

Ignoring all the cd commands, pretty much you say this command does not work?:
copy c:\windows\repair\system c:\windows\system32\config\system
-and the system file exists in \repair? If it does, oh dear, it should copy, it should not have any attributes set to prevent that.; if it does not exist, oh dear. You could then try copying all the others and then attempting a restart of Windows...
The only difference between your method and the one I follow is that I copy out the 5 \config folder files to a tmp folder, delete them in \config and then use that command above, or a form of it...
-in effect, no difference. So I don't know, sorry.
I guess you could try [in RC]:
attrib -s -r -h c:\windows\repair\system
and so on for any other files...

Gerbil hit the nail on the head with his point about backups - I got so fed up with wasting time trying to recover, then giving up and reinstalling system and programs, that I re-partitioned my (80Gb) hard drive into 3 - system, data, and archive.

All my documents, letters, website designs, pictures emails and favourites backup etc go in the data disk, and I use norton ghost to back up the system and data at least weekly or after any significant change. I usually keep the last 3 or 4 backups, then ditch the oldest

It takes 5 to 10 mins to restore my XPpro, but I use erunt to back up the registry (to the archive partition) so if I get funnies after installing something new I can restore the registry in less than a minute. I recently upgraded my system and the faster disk access and processor have halved those times

When you next have to reinstall, this is the way to go. Best of all is to put your backups onto a separate physical disk, in case the HDD goes down.

Hello, I too have this problem. I tried the steps from the Miclonestuff, I mean Microsoft,support link but I cannot, or it will not let me, get past the first line- copy c:\windows\system32\config\system c:\windows\tmp\system.bak, I get a message saying it cannot be copied, does this mean a reformat and total re-installation, or have I missed something.

The Toshiba disks are used to recover your pc incase of emegerncies(i'm not really sure) but if you put them in, u might lose all your data
