Hi. I had Ubuntu installed via wubi and been using it for some time now. Never had problems until today.

The screen where it displays Windows XP and Ubuntu gets shown, I choose Ubuntu. Then the second screen with which you can choose Generic, Generic (Recovery Mode), etc (Sorry I'm a newbie and I don't know what it's called) doesn't show. It goes to the grub command line and honestly, I don't know how to get past that.

Please help, thank you.

Did you make any changes or do any updates just prior to this occurring?
Check this site, Section 10, Command Line and Rescue Mode:

https://help.ubuntu.com/community/Grub2#Command Line and Rescue Mode

Were you using the xp bootloader to boot both systems?

I did not see any updates as I run the update-manager on startup. It was working the night before.
And I think I've always used grub when booting up whether windows or ubuntu. Thanks, I'll look into that manual.

Hi. So Tried the steps in the section "Using CLI to Boot" from the link given, also the steps in this page:
http://www.lemmonaid.info/computers/...o-wubi-ubuntu/

Here's my setup. Windows XP is on C: partition, and Wubi is in D:\Ubuntu. When I set root to loop0, and type "linux /boot/vmlinuz- and press TAB, it doesn't show any kernels available. When I hit enter, it says something like "the disk isn't available".

When I set root to (hd0,1) (C partition), it doesn't find any kernels, but there's this folder: (hd0,1)/boot/ and the fles are BCEDIT and something else.

When I set root to (hd0,1) (D partition), no kernels, no boot folder whatsoever.

I'm really stuck and I don't know what to do next. I don't have much files on my Wubi installation, but what I'm actually trying to save is the programs I've installed and the settings I've had. Thanks people.

I would suggest you read this instead.
(note: I've never used wubi).

Oh wow. I know why the steps wouldn't work. I just found out that /disks/root.disk is gone from my wubi installation. Wow. And I don't know how that happened. I hope system restore would fix this Thanks anyway guys.
