BIOS on Asus M5A78L-M - EFI possible??

[wlk461]

I transferred a GPT disk from my dying laptop to my new computer. The BIOS doesn't seem to have the usual option of LEGACY/UEFI in Setup, but complains if I try to boot this GPT from it, saying I should reconfigure to UEFI, but there doesn't seem to be any option in the Bios setüp. Having booted from a MSDOS-type partition the system accepts a second GPT disk, will even (using Gparted) let me set up a new GPT partition table , but will not accept this disp as Boot. when selected at startup with BootSelect F8.
Has anyone used Uefi with these MB?

If it doesn't have UEFI BIOS than you can't use OS set for UEFI. .

I am aware of that.

The question was IF the Bios has GPT, which one could reasonably expect in 2017 . The manufacturer says yes, but nowhere in the documentation or Bios settings does it say HOW to set GPT

It's not set in BIOS but in partitioning of disk
MBR https://en.wikipedia.org/wiki/Master_boot_record
GPT https://en.wikipedia.org/wiki/GUID_Partition_Table

That cannot be correct as the 2 disks came from another UEFI machine & were already GPT.

All other BIOS' I have ever used have the explicit option in BIOS setup to choose between Legacy and UEFI. This AM BIOS doesn't offer this option anywhere in Setup as far as I can see

Legacy or UEFI yes but that doesn't change disk formatting all by itself.
