Nothing happens.  I am completely stumped.
All I have is a DVD and a HD.  I am trying to boot the to DVD to install widows(again) it just will not do it.
If I go to BIOS features.  the boot option priorities are there. There are 3 at this point.  
Option 1 has 
boot mgr
HD
DVD
disabled.  I cannot move any of them.  Clicking or selecint the DVD does not change anything.
There are 2 other options but they have the same items in them.  I cannot figure out how to move anything. 

At this point i'm getting 'select a proper boot device and hit enter'
Editing.....
There is also a section for HD boot priority and CD/DVD boot priority and they each have one device in them and the option to disable.
