Downgrade 8 to 7 on Acer Aspire AXC-603G-UW31 ACPI Compliant Error

I have a Acer Aspire AXC-603G-UW31

It had Windows 8 I took the drive out and hooked it to another machine. I have tried Windows 7 32 and 64, neither seem to work. The drive is brand new and works in the other machine just fine. I know its something in the Bios but can't seem to figure out what. There isn't that many options in the Bios.... There is no Bios update either and even if there was an update how could I install it?

I keep getting the famous,

The Bios in this system is not fully ACPI compliant. Please contact your system vendor for an updated Bios. 0x00000045 error

After trolling the net for 2 days I still can't get this figured out.

Please any help would be great!

Is there are newer BIOS firmware update?

From your screenshots it appears you are in Legacy Mode if that's what you want. Technical Note: UEFI BIOS vs. Legacy BIOS, Advantech(EN) - YouTube

If not disable Legacy in Boot Options, set CSM to UEFI first.

You might try wiping the HD in the other PC with Clean Command Disk - Clean and Clean All with Diskpart Command to clear any GPT formatting, but the error is pretty BIOS-specfic. Have you tried the UEFI settings only?
