XRS

I just downloaded the latest XP updates from Microsoft and rebooted the machine. Then I got a BSOD with "STOP: C000221 {Bad image checksum]. The image urlmon.dll is possibly corrupt. The header checksum does not match the computed checksum".

I looke dup the error through Google (on another machine) and it suggested I copy a fresh file onto the hard drive. The only problem is that although the BIOS sees the hard drive a bootable floppy cannot. The PC also has a separate drive I use for Windows 98, and this works OK except that I still can't see the hard drive.

Any ideas out there? temperature related? (I leave it on 24/7 trying to catch up with Mr Footlong on UD)

Mr.Cookie

not sure but i think the 98 machine doesn't see drive coz it's ntfs rather than fat32, have you tried booting from xp cdrom and trying the repair option.

Which OS have you got on the C: drive (primary boot partition) and which other ones on the other drives? Are the drives physical or partitioned?

Of course, I have NTFS on the C drive! - completely forgot!
Anyway, I found a copy of the offending file (from another machine), fired up repair console and copied it to c:\windows\system (as on the other machine). There was no previous version on mine, but I assumed that it could not see it because it was corrupt. Still no luck yet though, BSOD still comes up.

Any more ideas please?

Now solved. It would have helped if I had copied the repaired file into the correct folder first time.

Thanks for the inspiration to realise that my hard drive had not in fact failed.
