Yes, EFI will reject 32 bit installs.
Do you see a special BIOS setting to use dual EFI/Legacy BIOS methods as I've not heard of it yet.
You can try to install Win7 32 bit to an MBR disk using the non-UEFI HD and installer DVD/USB choices which apply if they are present. This may actually be faster than extended research though I would direct it to your mobo tech support or forums if needed.
Unplug the other HD if you want to try this, as per Ray's comment below. Post back any error message and step it fails in Clean Install Windows 7
