Boot Sector Problem
 

I resized my reiserfs partition on my laptop with qtparted on a live cd. When I try to boot it now says: No boot sector found, restart your computer.
What happened, and how can I fix this without losing information? Thanks for your help.

what boot loader are you using?
you may have to boot with a livecd, mount the boot partition, chroot to it, check lilo.conf and run lilo again (if you are using lilo) not sure about grub, never used it
