I bet this question has been beat to death but maybe I'm not looking for the right question. When I get a new distro of linux (say Debian 8) and burn the ISO to a CD/DVD I get a bootable, installable disk. This also is the same from things like SystemRescueCD -- which I use extensively. But if I try to do the same with a flash drive, I get some menu system that Unetbootin installs, that is hit or miss useable. To this date I've yet to get a bootable flash drive that actually /works/ reliably from a flash drive. So I'm assuming that Unetbootin doesn't work, and I've not found any thing that works from linux. So is there a way to make a flash-drive version like you get on a CD/DVD? Ultimately there won't be CD/DVDs so is there a solution that works?
