While I was in Windows 7, I once changed my System Settings to have Ubuntu starting automatically, and since then I don't know how to run Windows again (what a stupid thing I did). Since I can't run Windows, I'm unable to uninstall Ubuntu, which I have installed inside Windows, as Wubi. Please let me know if there is anyway I can solve this problem.

I'm using Windows 7 and Ubuntu 13.04.

  • Try F8 at boot?

Install grub. It is the only way possible to recover it strictly from Ubuntu. Other methods are possible but GRUB is the easiest. It is very simple to install as well.

Right from Ubuntu's support pages:

sudo grub-install /dev/sdX  # Example: sudo grub-install /dev/sda

If you later wish to return to the Windows Boot Loader, it is possible and there are many guides on the internet. I would highly recommend that you install your own partitioned and completely seperate Ubuntu. It works much more elegantly.

  • It's a wubi install - this doesn't work. Luckily if you run that command from a Wubi install it will ignore it.
