Hi, new to the forum. :)

Having a bit of an issue booting from a cd. Seems there are two methods to choose from in the bios, UEFI or legacy.  If I choose UEFI the system will not boot from cd, its not even a choice when pressing F12 on boot up.  If I set the system to legacy, it will boot from a cd but no longer sees the hard drive as a boot device.  I have the boot order set to 1 cd/dvd  2 hard drive.  This is on an aurora R4 by the way. 

Thanks
