So, I installed Ubuntu 12.10 via the Wubi installer. It told me to reboot. I did. Everything was fine until then and I got a boot menu with two options. Windows and Ubuntu. When I clicked the Ubuntu option, I got this:

I'm clueless as to how to fix this. Any help?

(.mbris the Windows file extension for an image that can be written to the MBR or bootstrapped by the Windows boot loader itself.) The MBR is fine here, or the Windows boot menu wouldn't have come up and Windows itself wouldn't boot either. The whole point of Wubi is the MBR and partition table are untouched. Trying to repair the MBR by reinstalling the Windows boot loader won't help. (And trying to repair the MBR by installing GRUB to it would be a disaster, but I know that's not what you were saying to do.) – Eliah Kagan Dec 29 '12 at 18:40
