I installed Ubuntu 12.04 LTS yesterday, and ran into a few problems (Windows not booting..) However, I think I fixed that by booting windows 8 in 'UEFI recovery' (or something like that) - there is no discernible difference between the Windows I am running now and the Windows I was running before.
However, I would like to uninstall Ubuntu, but I don't want to mess up my computer (again!) How do I go about doing this safely?
I did some research and found these 2 conflicting YouTube videos, explaining 2 different ways of doing it: which way should I use? And if none of those YouTube videos are correct, which way should I use?
I am using a Lenovo Z500 laptop, if that's of importance.
Thanks in advance.
