I'm trying to install Linux Mint 14 to replace my current Linux Mint 9 installation. I've had no difficulties creating a startup disk (actually a USB flashdrive). The problem arises when I make an attempt to boot from the flash drive. You see, I am using a laptop with a damaged screen, so the only screen is an external computer monitor plugged into it. Since the computer monitor doesn't turn on until after my current installation begins booting, I am unable to see what I'm doing, making access to changing boot order well-nigh impossible.
