Hello there, Getting a 2011 13" MBA next week and have decided to install windows 7 on it.I need to use windows a lot for my college work as I'm studying computer networking so really cant be done without it. I have a superdrive already so I understand the installation will be a piece of cake but just have some questions before I do. What's the best version to install, 32 or 64 bit windows? I'm thinking 64 for performance reasons but does bootcamp provide all the right drivers for 64bit? Also I've read that AHCI will be disabled in windows 7, is there a way to activate this instead of running in ide mode? Would TRIM be enabled in ide mode if can't do this? Also how easy would it be to backup and restore my windows 7 install in case it fails? Would I be able to restore a backup of windows using a cd booting from the superdrive ?? I think thats it for now, thanks for any help!
