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?
Windows8-ReleasePreview-UpgradeAssistant.exeonto? If so, that's not going to work. I know very little about Windows but I'm guessing that you will need to use a real Windows 7 Installation CD to install Windows and then you can use that file to upgrade to Windows 8 once you've already installed Windows 7. – adempewolff Jun 5 '12 at 9:24
