I have installed Ubuntu 12.10 on my laptop, but would like to install windows for the purpose of gaming (Hallelujah). But I haven't left any unpartitioned parts of the HDD so now I am stuck on (How to remove one partition from ubuntu and use it to install win7 in a safe way?) I do not want to reinstall everything all over again, but definitely want to play games on my laptop.
I do not want alternatives with Wine or PlayOnLinux, cuz I have runned a few games and they were all buggy, I want dual-boot.
