Installing Windows 7 from a USB Hard 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?
Extra - "
My bios should support it as i have previously installed windows 7 from a usb flash drive, my current problem is that no matter what i option i choose it simply skips and loads the current OS from the hard drive. I have made the device bootable and such but no luck. (Yes i have already makred the partition as active)."
P.S. Can you not close this as it is NOT an exact duplicate... that other question is for a usb FLASH drive not a HD.
