freeness won't boot

[the gamer that is bad]

i have installed both freeness, trueness, and ubuntu to several different usb drives but it will just stay on the booting screen even after i leave it for days at a time the system is a dell opteplex or whatever it is with some ram upgrades 12gb total and an 3rd gen i5 are there any tricks I can use to get a nas out of this computer? the computer will boot to windows tough but nothing els.

What screen does it stay on? 

 

Have you tried booting from different media?

 

What model of optiplex?

 

How are you making the bootable usb?

If it's a newer version of Freenas (I believe >11.1) it will throw a fit unless it's UEFI. Look in the BIOS to see if you can switch to UEFI and try re-installing.
