I have a problem with Ubuntu 11.04. I've installed Ubuntu 11.04 from Windows, it worked fine for days, but today it won't boot.
When I start the machine, GRUB loads. There is the Windows 7 loader, I select Ubuntu from there and after that, I should see the Ubuntu GRUB menu, where I'd select the mode to boot Ubuntu. However, I can't see that any more. I directly get to a GRUB terminal.
Can anyone help me with this? How would I recover my data or reset the boot loader?
