[SOLVED] asus strix z390-E can't change boot order

[jacob.pedersen.1202]

Hello,

I have recently build a new PC system with the following specs:
CPU: i7-9700k
Motherboard: Asus strix z390-E
GPU: Asus Strix gtx 1070
RAM: Corsair vengeance RGB PRO 2x 16 GB
HDD: WD Red WD20EFRX 2 TB
SSD: Kingston KC400 1 TB & Samsung EVO 128 GB

In the bios all the drives are detected, but I am not able to change the boot order, where non of them are shown in easy-mode right-hand side boot order window. There is already installed Windows 10 on the Kingston SSD, but it won't even boot to that.

Any possible help with this?
Best regards

Flash latest UEFI ?
Disable all but the windows drive.
Put SSD at top of boot device options under the BOOT column.

I changed the CSM from Disabled to Enabled which allow me to change boot priority.
