I have followed the guide to install Windows 10 and after installation is complete there is no Windows Boot Manager option in the bios, I have reinstalled it 4 times with no luck, tried all pcie ports on my motherboard and the Rufus stick is made correctly and the NVMe drive is GPT.
Motherboard: GA-Z77X-D3H rev.1.1
BIOS: [OFFER] Gigabyte GA-Z77X-D3H NVMe mod
Only shown is PATA SS which I know cant boot.
