I am trying to use a W8 recovery USB drive (made with acer recovery management) in my S3-391. The computer will not boot at all with a USB drive in either of the ports. Upon power-up, the computer shows the "Acer" screen, then the screen goes black, then the "Acer" screen appears again, and then the screen goes black again. It loops like this until I hold the power button for a hard shut down. Tapping F2 or Del doesn't bring up the BIOS or do anything else. The computer boots up fine into W8 and BIOS without anything plugged into the USB ports. I am still running BIOS v. 2.07 but I am not sure if that has anything to do with it, since I can't get to the BIOS at all with the USB in. I have never updated a BIOS but I'm decently computer literate and could probably google my way through it if you think it will help.
Has anyone else experienced this or anything like it?
Thanks.
