Thanks bvc, the partition is still there, it just got formatted and is now empty. Not familiar with the -i option on parted. I have only used it to recover partition tables.
Ix, everything was going normal until I rebooted after using drakX(?) to rename partitions on hdb and resized and formatted /hdb/boot. My mistake for taking the easy way out and trusting that thing.
In rescue mode, I chroot /mnt and /boot is empty. No config, initrd, vmlinuz, nothing.
