After recent system update (I think I saw something kernelish but don't really remember) my Ubuntu becomes unbootable. When I select "Ubuntu" from the boot menu, I'm greeted by a GRUB console and I don't know what to do (typing help shows some helpful commands for gods, unfortunately I'm a mere mortal).

I'm doing this on Windows XP now. How do I go back to the future?

Edit: The Ubuntu was installed using WUBI

A very nice description of the problem indeed, I like your style :) But I have 2 questions: are you sure it is a Grub console (looking something like grub >)? If so, can you post the output of boot_info_script from a LiveCD? – arrange Feb 28 '11 at 7:15
How did you install Ubuntu? Was it booting from the live CD and installing to a real partition or using WUBI and installing from Windows ? – João Pinto Feb 28 '11 at 16:53
WUBI, installing on NTFS – Ron Mar 2 '11 at 5:10
@arrange: the prompt is sh:grub>, boot_info_script: command not found – Ron Mar 3 '11 at 3:55

I think you will need to boot into a live CD and Recover GRUB visit this Community Documentation link - the steps are not that hard to follow you just need to be sure of the Ubuntu install partition and use the 9.10 install Cd you have.

Unfortunately I use WUBI – Ron Mar 2 '11 at 5:33
Simply choose Windows at boot and then you can reinstall from within Windows then. – Mark Rooney Mar 2 '11 at 8:40
okay I'll need to rescue my home first. Thanks. – Ron Mar 3 '11 at 4:13
If your happy using Ubuntu I suggest you format the partition and dual boot - WUBI is really really meant for those that just want to run Ubuntu inside a Windows environment and does sometimes have issues with updates that can break the installation, see for more info. – Mark Rooney Mar 3 '11 at 6:36
