EDIT: Feel I need to be more specific. I can't log in. I'm trying to run a repair from the XP setup menu.

Finally got around to finding an XP disk, and since I couldn't figure out how to just repair it, I did a clean install.

But now it says the pci file is corrupt and won't boot, and tells me to repair.

The question is, what do I do to repair it?

I get the question: "What OS do you want to be primary?"
One option, C:\Windows\
I hit 1, enter. And then enter the password.

However after that, it gives me something like a DOS prompt.

Just: C:\WINDOWS\
And it lets me type stuff.
What exact do I do?

If you have a damaged PCI.SYS, you need to get this file from
C:\I386\PCI.SYS
and copy it to
C:\WINDOWS\SYSTEM32\DRIVERS\PCI.SYS

I hope this helps.

sounds like to me. do you see a black screen with choices between 2 different xp installations when you cold boot. have you tried both? it sounds to me like you may have reinstalled in another folder so now you have basically 2 installs on your partion. that is fine. maybe the 'new' will boot without error. as for how to repair, you could either rerun setup and when it asks you if you want to install, you say yes then it finds your old installs (both of them in your case) and offers you to R for repair. you can try this on your original bad install. Or use the 'rescue' install to copy a good version of the file giving the error (what the heck is pci.sys anyhow) into the damaged os.

That one got me to. Did a google on it and this is what I got; pci.sys comes with a clean install of Microsoft Windows 2000 Professional.

Maybe you should reinstall and delete your partition and build again. Backup your C:\ Files. To delete partition enter D.

That's my tip.

Hellp Crazy Jim,

Not sure if you got this problem fixed yet, but here is where I would start:

Boot from XP disk

When it loads up hit "R" to "repair windows"

when you get to the DOS prompt run the following:

chkdsk /r (this could take a while)

chkdsk /p

and finally...

run fixboot

This usually solves the problem, but let me know.
