I have a dual-boot system, Ubuntu and Windows XP.
Ubuntu has been freezing occasionally. I've just been turning the computer off and back on when that happens.
The last time it happened, I turned the computer back on, it went to the screen where you select Windows or Ubuntu, I selected Ubuntu, and then it went straight to a grub interface instead of the Ubuntu startup screen.
When I hit Escape from the Grub command line, it goes to a menu of 8 items, but they all just return me to the Grub command line (except for "reboot" and "halt").
I tried the command "boot", but it says the kernel must be loaded first. When I tried "kernel", it says it requires some kind of filename parameter.
It's possible my 2-year-old daughter may have hit some key as it was starting up. Could that have made it go to grub instead of Ubuntu? Or could the Ubuntu partition be damaged?
Windows XP is working ok; I'm submitting this from there.
