Question ASUS Z97-A Boot Priority list issue

[johny_2000]

Hello everyone,

Recently I have found some strange behavior in the BIOS Boot Priority list of my Asus Z97-A motherboard in EZ Setup mode.

It shows a boot device named "ubuntu".

UEFI mode is disabled. Only Legacy mode and CSM boot is enabled for all devices.

At first I thought it was left on one of the hard drives.
I have only two NVME M.2 Samsung SSDs in my PC. No SATA drives.

So I removed both SSDs from the motherboard. Then I disconnected all USB devices. Then I reset CMOS with jumper, loaded default BIOS settings. Flashed BIOS with latest firmware. Reset it a few more times.

But I still have unknown boot device "ubuntu" in EZ mode only list. Literally everything has been physically disconnected from the motherboard and reset numerous times and it's still there. What a ...?

Welcome to the forums, newcomer!

You mentioned having two NVMe drives, the board you own only has 1xM.2 slot. Are you using the other drive on a riser card? Use EaseUS and pass on a screenshot of what you see there.

Oh yeah. I don't use the M.2 slot on the motherboard because it only supports x2 mode. Instead, I use two Asus Hyper M.2 x4 Mini Card PCI-Express adapters.
