Hey guys, strange computer issue here. The laptop is a Samsung NP300E5E. So here is the story.. I switched the laptop to boot from USB drive first. Now I went and tried switch it back (to booting from HDD) and access the setup menu by hitting the F2 key when the laptop starts. The laptop now just restarts if I hit the F2 key, and won't let me get into the setup menu. This is not the first time I have switched the computer back and forth to boot from the USB / HDD... So right now I can only boot from the USB, because I can't access the setup menu to put it back to boot from the HDD. I have never seen anything like this, what could be the issue? Thanks!
