I just recently bought an external hard drive and backed up my internal hard drive to it. I had to reformat the computer and I wanted to keep all of my files saved. Now I am trying to boot my computer from the external hard drive, but it doesn't seem to work. I have a dell inspiron 8600 and in the bios I selected usb storage device as the first boot option. For some reason, it is not finding it and is booting normally from the interal hard drive. Does anyone know what could be causing this?
