BSOD after partition crash

Hi, everyone. If I voilate group policy, bear with me, I'm new... but please tell me!

I have a Dell Dimension 3000 that originally had Windows XP Home Edition (I think SP3) on it. I made it into a multi-boot system with Windows XP and 7, Puppy Linux, and Debian.

After I installed Debian, the Windows 7 partition got corrupted, but not so bad that it was unreadable. Sigh... I ended up using a boot CD to manually modify the partition table. This resulted in loss of some Windows 7 files and the corruption of the XP partition. AAAAAAAAAAA!

I finally was able to recover the XP files with another computer. I then copied the XP files back to their partition. However, now XP won't boot right. I replaced some files using a Home Edition SP2 CD. These files included ntoskrnl.exe and smss.exe (there might have been some others, but I'm not sure what they were). A cool side effect of this was that I learned that ntoskrnl draws the famous XP loading screen. However, that didn't help any (other that replacing smss removed one BSOD error, only to be replaced by another).

When I boot my computer to XP, here's what happens:

• I go through the multi-boot rituals.
• The XP loading screen appears. The progress bar suddenly slows waaaay down for a while, then speeds back up for a little. (This is the SP2 ntoskrnl. The SP3 version just freezes.)
• A screen briefly appears (see first attachment) that says "autochk program not found - skipping AUTOCHECK".
• A BSOD appears (see second attachment) that says "STOP: c000021a {Fatal System Error} The Session Manager Initialization system process terminated unexpectedly with a status of 0xc000003a (0x00000000 0x00000000). The system has been shut down."

Any suggestions on how to fix this? I really don't want to have to do a Repair Install unless I absolutely have to. I have run a few programs on my backup copy of the recovered files and they seem to be uncorrupted.

Thanks a lot!

 

BTW, I also replaced hal.dll.

 

Ok, I feel really dumb for not checking what I replaced in the first place. Here's the whole list:

• autochk.exe
• hal.dll
• kernel32.dll
• ntoskrnl.exe
• smss.exe
• winlogon.exe
