Unable to uninstall ubuntu installed using Wubi

Solution 1:

If you cannot remove it from Add/Remove programs and the C:\ubuntu\Uninstall-Ubuntu.exe file does neither work, you can always do a manual removal.

See WubiGuide on Ubuntu Wiki for instructions.

Basically, the instructions in your case are:

  • Remove C:\ubuntu and all files starting with C:\wubildr
  • Remove the entry from the boot menu: Control Panel -> System -> Advanced -> Startup and Recovery, press Edit, select Ubuntu and press Remove.
