Anyone successfully running Windows 7 and Ubuntu 12.04 off the same hard drive as OSX? I'm thinking of switching to Mac, but want to check I can still use my other OS's if I need to. The Macbook Pro I'll probably order is the 13" 2.9GHz, without the Retina screen (assuming one is released) cause I'll use it with an external monitor at home. I'd like an SSD drive, but since it costs £720 extra and I can buy the same Crucial drive separately for £300, was seriously thinking of ordering with a basic SATA drive and doing that upgrade myself. Any thoughts?
