Question M.2 ssd not in the boit menu asus prime b350 plus

[Pncht]

Motherboard Asus prime b350 plus
Ssd Samsung 860 Evo m2

I installed Windows 10 to the m.2, with Linux live i checked that installation copied all Windows files to the m2 drive correctly and all disc sector are present, but motherboard wont recognize the ssd as a bootable unit.

(in the menu on the right theres supposed to be list of bootable devices. The m2 is the only drive connected to the motherboard so the list is empty)

So far i have tried
convert the ssd to GPT
Update bios - im using version released in 05/2019
Disable compatibility module
In the secure boot option use "Other Os"

Neither of these options worked.

Is there anything else i shall try?

If i install the Windows to HDD it will boot fine.

Go in to advanced mode, go to boot menu, scroll down to boot priority and see if it is listed there.

In the boot menu theres no such thing as boot priority.

I have boot priority in the main bios screen, in the first picture on the left and its empty.

Here i took some screenshots from the boot section and sata configuration.

How exactly did you do that?
If you installed in legacy mode and converted to gpt with anything other than mbr2gpt utility, then your system is unbootable now.
Bootloader needs to be recreated after this.

Yes you can only use GPT with uefi mode.
