I have ubuntu 14.04 trusty installed on my pc and it works good not excellent but as i want to play casual games what windows version will be good for dual boot.Plz prefer me the low and good windows.


There is only one version of Windows that matters now, which is Windows 7. Everything else is either deprecated (old, unsupported, dangerous to use) or really terrible (Vista, or Windows 8). So, that's all there is to it.

To remember: if you install Windows after Linux, you will have to reinstall the Grub bootloader and reconfigure it to know about both your Linux and Windows installation. Windows seems to think that it "owns" your system... :-(

Steam supports a lot of games now on linux not as many as mac mind you.
