make sure you do all the bios setting right, follow the guide carefully. make installer drive with the usb 2.0 ...last thing...remove nvme drive and install it in ssd....in my case,,,I didn't install it on the nvme drive, but nvme drive was attatching in my system...it still give me problem like freezing..so I had to removed it then finish the install..since my nvme is Samsung evol pro plus,,,I have to update the firmware in order to elimate the freezing problem completely...hope it help.
