Fix autochk endless boot loop w/out floppy

Hey there,

So I was working on a client's computer to find, after restarting, that the computer was all of a sudden stuck in an endless boot loop. It would start, show the loading windows xp screen, then a blue gradient screen would come up saying "autochk not found - skipping autochk" and then it would do the whole thing over.

I have found plenty of information online, but one of it is helpful in this case. This is mostly due to my client not having a floppy disk drive and therefore I'm unable to use PTedit to unhide the missing partition.

I have also read things similar to removing the harddrive and inserting it into a working computer, but that's not an option.

Is there anyway to fix this problem by booting from a cd and if so how?

Thank you,

-Steve
