I googled around and tried a bunch of things to install Windows on my MacBook. It simply won't let me boot off a USB flash drive. Has anyone found a solution to this? I tried: - rEFIt - starting installation with VMWare Fusion and finish of Bootcamp partition - boot directly from USB All I need to do is boot from USB. I know the USB flash drive is fine since I installed Windows on a regular laptop with it. I really need some help here!
