I was running Windows 8 prerelease and wubi (Windows Ubuntu installer). When windows 8 was released I upgraded. The wubi installation was having a lot of problems so I attempted to remove it. I couldn't uninstall wubi from "Add and Remove Programs" because it did not appear as an installed program.

So I downloaded the Uninstall-Ubuntu.exe on the wubi website and ran it. It seemed to work but I still had to manually delete the C:\ubuntu folder. I installed wubi again, but the problem is that now two ubuntu installs appear on the boot menu. These don't appear as partitions so I'm not how to remove the old one.

I can't find any info at all about this. Any help or advice would be appreciated.
