What Default Resets are offered on the Exit tab in BIOS?
I think your next step is to try the USB flash install formatting first the UEFI stick with UEFI boot enabled, then if necessary formatting the stick for MBR using Windows 7 USB-DVD Download Tool.
You can also try burning another disk with the tool above with a fresh ISO.
Get some sleep and check back with me tomorrow. I'll be here all day.
