I recently updated the BIOS to 2.1 and since then, i cannot find a configuration that will let me boot from the M.2 drive. I can, however, got into the F11 boot menu and select windows boot manager and boot fine after that... But cannot from native boot. no matter what config change i make.

If you are UEFI booting, the entry in the boot order for the OS drive will be Windows Boot Manager. You should also see the drive name in the entry, for example, "Windows Boot Manager: Samsung 960 Pro".

Are you saying that in the Boot screen, you don't have an entry in the boot order that is Windows Boot Manager? Or if you do and select it, the PC will not boot?

Otherwise, what do you mean by "native boot"?

Did you have the CSM option configured in any way besides the default settings before you updated to 2.10? If you did, when you updated to 2.10, all the UEFI options were set to their defaults, and CSM was set to Enabled.

For UEFI booting, that would be either:

CSM set to Disabled.

CSM set to Enabled, and the CSM sub-option Launch Storage OpROM Policy set to UEFI Only.
