How to uninstall windows 8 developer preview from dual boot windows 7

[cu2fond]

I have a windows 7 disk and I tried to use that a few times but it wreaked the disk, now how do I get windows 8 off my computer?

Hi

You can just format the drive in another machine or use a GENUINE 7 disc to format and install 7...

8 has NO uninstall....

All the best Brett
