File Corrupt inspect.sys

I was able to boot windows vista for the first time on installation.

However, when I tried afterwards, I have got this error when I try booting
into it:

File not fount/corrupt: inspect.sys

and then it tells me what I should do to fix the problem (Pop the windows
vista cd in, run recovery, run startup recovery). HOWEVER, the startup
recovery disk cannot even save me on this one. The only way I've managed to
post this is because I have done multi-boot, so I can access my previous
Windows XP. The only thing I've changed so far is put back all my Program
Files back from the Windows.old into their rightful location.

It also keeps saying if I have recently added hardware to the computer, I
should remove it and try rebooting. Unfortunately, I have not added any
hardware. Windows Vista was working perfectly fine last night, the only
problem I had was it not logging off correctly, so my only resort was to push
the power button and switch it off completely.

Can anybody offer any help?

Thanks, vytak.
