If Legacy BIOS settings are turned off, so that the machine will boot
only from UEFI an install of Debian 7 Wheezy will work: I have two
machines here installed just that way.
You will need to tab down to the advanced options as you boot the
installer and select expert mode : at that point, you can also
choose which desktop to install.
You may be able to install a very basic machine by using
dd to write the DVD image to an 8G USB stick.
