How to remove Ubuntu and put Windows back on?
I have a problem, because lately I installed ubuntu on my netbook and I decided that it worked faster with Windows XP and I would like to go back to it, but I don't know how to remove ubuntu from my hard drive without an live CD (because I don't have an cd-rom). I tried to find a solution, but I didn't find it anywhere. I would be thankful if somebody could help me.
