if you have a secondary drive or external try dd if=/dev/hda (or sda if sata) of=backup.img (where backup.img is a raw disk image of your drive, make sure to write the image somewhere on the secondary drive or external drive, not sure what happenes if you put the file on the same volume as you are copying from but my guess is that would be bad)
you may have to be root to do this
boot from the rescue disc and dd if=backup.img > /dev/hda (sda?) then fdisk /dev/hda and hit w to force write the partition table just to make sure
