Cannot clean-install Windows 7

Yeah I had to because I had WinXP, but I put the files that I wanted to keep on the partition that I made then W7 wiped the XP partition and I still had my files!

Aaah, but you cant if you only have one partition right ?
Also, now that I've got Ubuntu running nice n smooth, can I install W7 on a seperate partition?
(Ubuntu installs on a seperate partition if asked to, cant remember, but can you do the same with W7?)

I would only recommend installing Ubuntu and Windows 7 on the same machine if Ubuntu was the last OS installed in the chain. You always want to put the OSes with the most complex bootloaders at the end so, for example, Windows XP would come first, Vista/7 would come second, then Linux.

I suggest wiping Ubuntu and starting over.

Here's what you need to do:

1) Install InfraRecorder: http://infrarecorder.org/
2) Hit "write image"
3) Select your Windows 7 ISO
4) Wait
5) ???
6) Done
7) Install Windows 7
