I can't find anywhere on the internet that has this specific question.
The problem for me is I forgot my pass for Ubuntu 13.04 and now I can't use sudo commands. So now I need to change the boot and I cant do it. I want to make the default boot Windows on grub2.
Any ideas? If worse comes to worse can i delete the ubuntu partitions from windows then repair the grub so it will only show the windows os.
