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.

I don't think you are allowed to say that password here :p – ZOMFG Jul 24 '09 at 18:33

@ZOMFG, it's on the SO blog, it's public information as far as I'm concerned :) – bdonlan Jul 24 '09 at 18:34

I'm assuming you used Wubi to install it (if you booted from a CD to install, edit your question to reflect this or something). What's in c:\ubuntu\disks\boot on your windows machine? Also, add the contents of c:\ubuntu\disks\boot\grub\menu.lst (open in wordpad) to your question as well. You can format it properly by selecting it once it's pasted in, then clicking the 101010 button above the editor.

Edit: Based on the errors you give, your windows filesystem is corrupted. You need to run chkdsk as soon as possible. If you still have trouble booting after that, please add another comment.

In My Computer, when I try to open the C drive, it says "Windows cannot find "RECYCLER\'..." On the command line, when I try to open C:\ubuntu\disks it says "The file or directory is corrupted and unreadable." – JoshMaurice Jul 24 '09 at 18:51
I'm trying to run chkdsk, but I get the message: "Chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts? (Y/N)" I chose yes, and restarted, but it didn't seem to run the check, and gives the same message when I try to run it again. – JoshMaurice Jul 24 '09 at 19:24
Boot from a windows CD, and go into the recovery console. Then run chkdsk from there. – bdonlan Jul 24 '09 at 19:46
