Before I provide you the directions to uninstall Ubuntu, I urge you to give it another chance. Whatever issues you're having are probably solvable. There's a very large Ubuntu community to help you out with any issues you may have.

That said, to completely uninstall Ubuntu you need to have a Windows CD available or access to the Windows Recovery Console (or just the CD for Windows Vista+).

If you installed Ubuntu from inside Windows (Wubi install), go to the very last section.

Boot the Windows CD.


  • While the CD is loading it will tell you to "Press 'R' for System Recovery." Press 'R'.
  • This will drop you to a black and white console.
  • Select the Windows you want to do recovery on (usually there's only one)
  • Enter your Administrator password, if any.
  • Enter the command: fixboot
  • Followed by: fixmbr
  • Reboot


  • Boot the CD
  • Select your OS (usually only 1 avaialble)
  • Tell it you want a command prompt
  • Enter the command: bootrec /fixboot
  • Enter the command: bootrec /fixmbr
  • Reboot

In Windows:

  • Go to the Control Panel
  • Click on Administrative Tools (you may have to select "Classic View" on the upper right)
  • Open "Computer Management"
  • Select Disk Management
  • Click the drive you installed Ubuntu on (usually C:)
  • In the bottom of the Window, you'll see a blue section and probably a grey section.
  • Right click the grey section and delete it.
  • Then, right click the C: section and resize it to fill the disk.

Wubi Install (installed from inside Windows):

  • Start up Windows.
  • Control Panel -> Add/Remove Programs (or Programs and Features)
  • Find Ubuntu in the list and uninstall.
  • OR run C:\ubuntu\Uninstall-Ubuntu.exe
