I'm new to linux first off, and I have a Dell inspiron 5150 P4 2.8ghz w/512 mb RAM. Anyway, I had XP Pro installed and I decided that I wanted to try out Fedora Core 3, so i d/l the iso and burnt it correctly, I installed everything and no probs to speak of, however I couldn't get back to xp from grub boot loader, when it started windows it said "autochk file missing". So I reformatted my hd and installed just linux, no probs. Mow after a little research I think I know how to get the dual boot working, but when I rebooted from xp Pro cd it says please check your systems hardware configuration and then the screen goes blank! ( I caught something while linux was loading that said something.... "0.4% uncontigious". Now I can't get boot from XP cd, what can I do????
