it... does... not.. matter... Windows lets you delete and format the drive the way it needs it to be, but fat w/ Master Boot Record (Windows partition table) in Disk Utility: partition: Advanced option.
Then pull all the other drives.
Pretend you have to start with raw drive, no OS, and DVD in hand.
Does it slow down your system if you install windows on it? I just a new retina macbook pro? Would it be wise to install windows 7 on it? Can i then use all the windows related softwares on it that i would normally use on let's say my old Hp laptop made just for microsoft windows?
Thanks for answers.....
You dont' have a Mac Pro. This was about situation different 200% from yours.
Getting this moved to Boot Camp;
The MacBook Air under Windows doesn't support Turbo Boost for now.
Of course you can install Windows natively or in a VM. A VM would have to share memory and processors, that is why people dual boot and run Windows natively on its own partition.
