Re: 11.04 on an Asus 1215b?
I recommend you start a new thread to resolve your problem; "hijacking" another thread is generally considered bad form, and it can get very confusing trying to resolve two problems in a single thread.
That said, you may want to try ELILO rather than GRUB 2; in my experience, GRUB 2 on UEFI systems is barely functional and very trouble-prone. See my post (#5) in this thread.
If I've suggested a solution to a problem and you're not the original poster, do not try my solution! Problems can seem similar but be different, and a good solution to one problem can make another worse. Post a new thread with your problem details.
