wow! the solution is so easy. just put in fedora core 1 cd 1.
type "linux rescue"
follow the instructions
at the command prompt type "chroot /mnt/sysimage"
there! you'll get root permission without any password prompted and can modify, copy, delete anything you want.
i think i better set my bios boot sequence to hard drive 1st else anyone with a fedora core 1 cd 1 can boot into my system and do anything
