Clevo bios slow with GPT partitions

Hi,

My bios is very slow to load, it takes about 10 seconds to go from cold to my bootloader (Clove).

My previous setup was MBR (windows 8) and bios booted immediately.

I'm not sure if it is caused by having multiple partitions, or because I'm using a GPT .

It's the same with both PremaMod & the stock clevo bios.

Is anyone else having this issue? Can anyone advise on how to help?
