Public bug reported:
Last night I upgraded 10.10 to 11.04. All went well except when I boot
my computer I do not get the grub bootloader display. Bios boots then my
monitor goes blank and gives me an out of range message. Then after 30
seconds or so I boot into 11.04. I tried to reinstall grub but no
difference. Grub does work though. If I arrow down 5 times I can boot
into Windows, etc.
When I run sudo update-grub, this is my output:
Generating grub.cfg ...
