Im not doing it for performance reasons i have 2 hardrives in my computer and would rather set up dual boot so one hard drive is with w7 for gaming, uni work, internet, torrents etc and then i want the other disk to be just for recording. Just to keep things separate and stop any chances of a virus getting into my audio hard drive. Problem is slimey microsoft wont let you install w7 twice..... even when both hard drives are in the same computer being run my the same hardware. Thats why i need to find a reliable version of an operating system.
