Hello,
I am new to this forum and relatively new to Ubuntu. I attempted to install manic on my Vaio today only to find that I could not boot because of an error:
Error: No such device <Alphanumeric stuff>
grub rescue>
Someone on another thread said anyone with such an error who is not using Wubi should start a new thread and post the results of the boot info script in order to get help.
