Install Windows 7 through USB Drive?
I have a portable HD and i want to install windows 7 from it as i have no USB or cd to work with. Is this do-able?
I have so far made a seperate partition on the drive and made it bootable but it doesn't seem to get recognized when i boot it up. Any ideas?
Also what would the boot option be under the boot section? USB - HDD right?
