Do you have it booting to the USB drive? Is the USB drive setup as a Bootable drive?
I did make usb bootable using rufus. According to Chapter 3 of the manual to change CSM Support to Disabled.
When I enable it, I am able to able to get it to boot to USB.
In the past I have used boot sequence to choose what order to boot but I can't change it in bios under bios feature.
The area I circled in blue is there I should see the boot option for USB right?
I just want to know am I doing it right. I followed the steps in chapter 3 and created the raid. So all I have to do is just boot in USB and I should be able to install windows right?
