I needed to wipe my entire mac HDD as there was an issue with something, bad move i guess now, however, i am planning to reinstall windows on the mac using a bootable USB. At the moment, there is no os on the macbook whatsoever. Yes it would be a wise move to just reinstall mac osx first however i do not plan on using it at all, this mac was given to me and i prefer to use windows, ive used windows perfectly in the past before. Currently i only have access to a windows computer, an 8gb usb (for the win 7 installation), 4gb usb (using rEFIt) and the mac itself. I have attempted several times mounting the bootable win7 image to the USB. Ive tried multiple formats NTFS, FAT32, even HFS+. Despite the macbook being able to recognize the windows boot option in rEFIt, once selected and chosen the mac does not boot from the usb, and the windows installation does not open, it simply goes to the second boot option which is the HDD (where no os is currently installed) Advice please?
