When I try to run something with wine, nothing happens!
I have had many problems with Ubuntu so I have tried to get Windows 8 back on the computer, but because Ubuntu can't run exe files I can't open the installer.
Furthermore my computer can't boot from a CD/DVD anymore after I installed Ubuntu. It turns up with a black screen with a blinking marker at the upper left corner of the screen and after 10 minutes it says something like:
Can't boot from the selected media device - select another!
How do I get Windows back?
