well my brother has bought exactly the same setup, all he had to do was disconnect the HDD and SSD from the mobo and remove the power to them, then he left it in the boot loop and in around 5-10 minutes later an error message appeared saying that there was no HDD or SSD connected and the he clicked Ctrl, Alt + Del and he could use the bios freely and he managed to update the bios, for some reason when i try to do this i get no error message and i am constantly stuck in a boot loop.
