The "OS not found" part is somewhat scary.  If this happened immediately
after the power glitch, then I would fear hardware damage or failure. =(

What you can try is to mount your partitions from a rescue disk.  Your
Knoppix is a pretty good rescue disk, alternatively Red Hat or
Mandrake's Disk 1 have excellent Rescue functionality too.

What distro was originally on the hard drive?
What filesystem?  ext2, ext3, reiserfs, XFS, JFS, etc.
