Since you've rebooted, /dev/hda2 has been mounted on /programs0, and the contents of /dev/hda2 have thus obscured the contents of /programs0/ (the directory on the root parrition).

Try:
umount /programs0
ls /programs0

and you will probably see preinit.d
So, after having done this,

rw
cd /programs0
mv preinit.d /etc/
cd /
./mkprgpt


Yeah, you're right...even with the script, it still takes a willingness to learn and understand a smattering or more of linux principles and commands. I want to get this down to point and click.
