How do I remove Ubuntu?

My friend installed Ubuntu on a separate partition on a PC with Windows 7 using Wubi. But by mistake he reformatted the drive containing Ubuntu. He is still getting Ubuntu option in the boot menu. How can it be completely removed?

• You will need to uninstall Ubuntu from Windows 7 - you can do this in the Add/Remove software section of the control panel or by running Wubi installer again (It should inform you that you need to uninstall first).

• You can also use EasyBCD to remove the boot option, but you should try uninstalling first. http://neosmart.net/dl.php?id=1

• I don't think its Ubuntu problem.

  (assuming that you are using windows)

  You have to edit your boot.ini file

  Run->msconfig->BOOT.INI->check all boot drives

  If it does not find any OS mentioned in boot.ini file, it will shows you an error message saying that your path is invalid and asks if you want to remove it. Just conform it and you are done.

  Works in windows XP. I hope its same in windows 7 too.

• Try this tutorial: Easily Set Default OS in a Windows 7 Dual-boot Setup

  In the last step change the dropdown to Windows 7 (there should also be a Ubuntu/Wubi option). You can also change the "Time to display list of operating systems" to '0', or something very short.

  

  Alternatively you can try the Ubuntu Wiki instructions for manual removal of Wubi.

• The question is if it is Grub or the Windows boot menu that your friend sees?

  Grub in the MBR requires rewriting the MBR which isn't easy from inside modern versions of Windows.

  THe Windows boot menu can be fixed in the System control panel.

• If Wubi does not appear in Add / Remove programs, you should be able to download it again, run it, and it will jump straight into the uninstall process.

  If that does not work, the following manual steps will get rid of it, save removing registry keys:

  1. Remove the Wubi directory, if present.
  2. Remove any wubildr files in your C: drive.
  3. Use bcdedit /delete to remove the Wubi entry from the Windows bootloader.
