It took me sometime to try the optie explained in the previous reply. It works, but one has to be carefull that the GRUB loader does not change the active partition. When the GRUB settings are automatically generated by your linux distribution, it will probably have the following lines in /boot/grub/menu.lst to load the windows OS. root(hd0,0) makeactive chainloader + 1 boot This will make the partition were windows is on the active partition, so after windows is booted GRUB will not load. By removing the 'makeactive' line solves the problem. Now I can start doing some serious vliting to make my optimal gaming OS.
