Managed to get hold of the Windows 7 beta...*cough*cough. Instead of screwing my system, the Win7 is installed in VM ware with single core, 1gb ram, 20gb hard disk configuration.
The whole installation took around 15 minutes, that's real fast! The OS itself occupies 8gb, run smoothly on the virtualisation using around 400mb of ram. 
Okay, that's enough of talking, more pictures following.
