I have a HP DC8000 SFF PC with a 250GB HDD and 8GB RAM running ubuntu 14.04LTS which i use for Steam linux games and it works very well with the Nvidia GeForce GTX 750 Ti graphics card installed.
I really want to be able to run some windows Steam games (No Mans Sky actually is the only one!) I know I can install a fresh ubuntu and leave existing windows OS in place but i dont want to have to re-install my current version on ubuntu as ive got lots of mods for other games ive compiled and it would take forever to re-build.
so, can i add an additional HDD and install windows on it so I get the option to choose between the ubuntu HDD or windows HDD in the grub boot menu (dual boot it i guess?)
