I'm using a Toshiba Satellite Laptop and am trying to boot a small hard drive with windows 7 pro as the os. Entering the bios shows that the computer recognizes the hard drive as a hard drive providing the applicable details about it. Trying to boot it only brings a message that says, "No bootable device -- Please restart system". My boot priorities show that HDD/SSD will boot first. I'm just getting into coding and would really like to use this hard drive. Any help?
