I've just installed Ubuntu 12.04 LTS, and after a little work, I found out I want to have it dualbooting with Windows 7. After more work, the forums and posts say it's a good idea to have Windows on first, then add Ubuntu. So I got my copy of Windows 7 (known working) and made a bootable usb stick with it.
When I attempt to boot from the usb stick, I get a black screen for a couple of seconds, then Ubuntu boots. When I attempt to start install from Ubuntu by running "setup.exe" in Wine, it tells me it cannot find a place to store temporary files.
How do I use this stick to clear my hard drive and install Windows 7 so I can install Ubuntu 12.04 LTS afterwards?
