Installed the new version of Ubuntu (8.10) on supossedly a different Hard Drive (aside from my Windows XP Pro installation to see how it compares), but my XP system (primary HD) fails to come up by itself.

Now, If a I tried to bring up my XP without my second HD (where I install Ubuntu), GRUB starts and shows Error 20 on the screen. Nothing happens after that. Otherwise GRUB works fine and let me select through the different OS.

Tried FIXMBR and FIXBOOT, but GRUB stills comming up. Don't know what else to do. How do I resolve this problem? Could anyone shed some light on the subject?
