i Recently bought an HP Envy cpu with windows 8 on it. It also is running UEFI. It has a default 2TB Hard drive, I added two more 1TB drives to the cpu.

I then tried to reboot the machine to get it to read the dvd I had put into the machine. I am trying to set the cpu up to DUAL BOOT. Yet it won't read the dvd. This is a Redhat Linux DVD from the class I recently took and I am fairly sure it is ok, however I will create a new dvd to confirm this. Any ideas why the cpu wont read the dvd?
