what format should my usb drives be for boot camp
I am Installing Windows 7 Home Premium SP1 on my late 2012 Mac Mini. I have the S/W on my desktop as an .iso format, and my test to check if Boot Camp would find it worked. Now I will be getting an USB drive (my 4GB wasn't big enough so will use it for the drivers), so before going on this process trying to cover all bases. I'm assuming an 8GB thumb drive should be enough. I'm also assuming the 4GB drive formatted in FAT should be ok since Windows 7 has to read it, does the drive for the disk image have to be MAC Ext'd or FAT?
Any help on this is appreciated, I'm pretty new to all this stuff and hate running into problems during this process will be hairy! Any other pointers is greatly appreciated.
Mac mini, OS X Mountain Lion (10.8.2)
