I have just installed Ubuntu (linux) on my second HD. When going back to Windows to get password setting etc, it comes up with the blue "welcome" screen with the usernames on. I click on mine (or any other for that matter), and you hear the startup sound, it says "loading your settings", then just does nothing.

The screen isn't frozen, because I can still move the mouse cursor. On trying it again today, I pressed Alt-tab a couple of times and ctrl-alt-del a couple of times and my wallpaper image came up, but no task bar or buttons.

Can't boot from a Windows cdrom either at the moment, as the Grub (linux boot loader), won't let me even though the BIOS is configured to boot from cd rom. If I choose windows from GRUB, then F8 to go into safe mode it boots me into Ubuntu.

I can still access windows folders and files from Ubuntu, so if I need to change anything I should be able to.

Any suggestions? Cheers.
