Comment 11 for bug 609815

Hey. So, those 'steps to reproduce' are exactly what I did for this to happen.

After the installation of Ubuntu through Wubi from Windows 7, it worked fine. I got to boot in my system normally in all OSes. I ignored the Ubuntu updates in the first time, but then I decided to download and install them. During installation a GRUB Update window popped up asking whether I would like to update the GRUB. I'm a Linux noob and I didn't even know what was grub, then I chose to update it. After that I couldn't boot again. I got that same thing, "error: no such device <hex numbers> grub rescue>". Also I don't know if this makes any difference but...I have 3 partitions, D: with Windows 7, C: with Windows XP and E: just for shared files. The location Ubuntu was installed from Wubi was E:, since I usually use E: to store big files, like Virtual Box HDs for example.

The guys at #ubuntu helped me a lot throughout the whole day (Thanks :D). We tried A LOT of methods to try to fix the boot loader. But in the end, when I found some old CD-RWs and could burn the Windows 7 Recovery disc, the Windows 7 boot was recovered with one click. But I still cant boot in Windows XP and Ubuntu, I get errors when I choose any of them in the boot menu, something about corrupted or missing files.
