Other Linux distributions

Using the Latte Panda 3 Delta

Trying to get Slackware or Slackware based distributions working, completely due to personal preferences.

Every time i try to boot it would get stuck on a blank screen with a non blinking cursor. Restarting will instead boot windows, also removing the USB boot option in the menu. I can only get the option back by flashing the USB again. Any idea to how to solve the problem or what caused it? or if anyone managed to get other distributions working, mind sharing how?
