Thank you thank you thank you thank you thank you.
Seriously.
After about two hours of hitting my head against the wall, I found my Knoppix boot CD, googled my error message, found this page, booted to my boot utilities CD, ran grub and unhid my hidden drive. I am now back in XP and will:
(1) Not be monkeying around with Partition Magic any time soon
(2) Resolve to answer THREE questions online in the next week to save other people with stuff I know.
(3) Thank martouf profusely from the bottom of my heart every time my computer boots up!
SERIOUSLY -- I thought I was in a pickle. You have no idea how happy I am. Thank you google and thank you linuxcompatible message boards!!!
