My Acer Aspire A7600U-UR24 came with windows 8. I made a recovery drive by choosing "create recovery drive" in windows 8. After making the drive i installed windows 8.1 from DVD. Some time later I tried to restore it back to factory with my recovery usb. Every time I try I get "windows cannot find a system image on this computer" even though my flash drive is plugged in. I tried booting from the drive, doesn't seem to work. Not sure if my windows 8.1 version not being activated has anything to do with it (I installed 8.1 on 2 computers from the same dvd didn't realize i couldn't do that) . but I think I should still be able to boot from the drive. I need help. I was thinking if the problem is my flash drive, can I somehow transfer the system image from one flash drive to another? here's the screens: at this point there should be an option for windows 8 but there's not.
