This is one of those nasty little quirks of loading an OS from a bootloader.
Just because the bootloader knows where to look for a drive, it doesn't mean
that it's going to find it. More specifically, just because a bootlaoder is ON
A DRIVE, that doesn't mean that it can see the drive that it's on. Silly, I
know.

Since you've already verified that the filesystem is intact, and that the
necessary files are there, the issue is that the bootloader can't find the 
drive that it's looking for. With a regular IDE drive this would usually
happen if you were trying to boot Windows from an extended partition. In your
case, it's probably just that the bootloader can't identify that a drive
exists.

You may also want to check the boot.ini on that partition (if there is one).
