bootloader fails after reboot after ubuntu installation

[DreamPhysix]

I installed Ubuntu 10.10 amd64 (and tried 10.04.2 as well) from Wubi under Windows 7 64-bit. When I reboot after installing it through Windows, I go to Ubuntu and the installation completes. Then it reboots again to finish the install of the OS. When I boot into Ubuntu now, grub does not appear. Instead, some initramfs stuff comes up in a console with no GUI and says some error stuff about root devices. I read that grub updates cause problems, but the installation never finished and therefore I was never able to go into Ubuntu to lock grub packages, etc. Please advise! I've run into this error on multiple fresh installs

when you see the grub menu, hit 'e' and check the 'root=/dev/sdXY'.
Then press ESC, hit 'c' and enter ls (lower case LS). Then report back on what you see.
