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.

XP:

• 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

Vista+:

• 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
