Just installed Ubuntu 11.04. But it boots only from usb. Seems like I didn't pay attention during selecting boot device.

sudo fdisk -l

grub updating or another "grub" operations don't work as I've tried. Can I just copy whole boot folder from usb to HD or smth like that?

Any kind of help is appreciated. Apologize for my newbie skills.
