Motherboard not support GPT partitions to boot

Hello everybody, I am trying to install the HiveOS in a motherboard Intel D945GNT model but that it isn’t suport GPT partitions to boot.

I can started the HiveOS with YUMI Multiboot using the USB to the boot with EFI and charging to SSD (with the onboard card video), but when I insert the Card Video RX5500 XT in PC, HiveOS broke after Linux Journal charges… I tryied ,many times and with different ways but I can’t success…

Somebody could help me a way to start HiveOS in that machine, please ?
