I have an ASUS x470 Prime mother board with bios 5406. I also have a laptop.

efibootmanager
No BootOrder is set; firmware will attempt recovery

The above software is supposed to show me the boot items within the bios.
It does not. It works elsewhere. I should see one entry for
Fedora32 gnome
Leap 15.2 beta gnome
Lindoz cinnamon
Deepin V20 beta deepin

Since all are new installations, all four cannot be in error.
Any way to advise me how to respond to the error message.
Supposedly I could create manual entries (man iefbootmgr -) but the values to insert therein make no sense to me.
Am I seeing a bios upgrade error?
With other tools, I should see fan speed. There too, I do not.

Your help will be appreciated.
efibootmgr works with the UEFI specification from Intel, The motherboard is for AMD processors. efibootmgr (Fedora32) works on my amd based laptop.

Do you get this warning message if you open a terminal and run

For /dev/sda.... /dev/sdd no error.

But
for /dev/nvme0n1 I get no error

Does the command apply to nvme0n1 drives? M.2


all report gpt as drive type, no reported error for any drive.

Boot to bios to see what it has. Should be similar to efi shell. I'd look at efi shell too.

Since you did get linux to boot to run sudo efibootmgr then I'd think it must have a default boot order.

If you have no warning, then it may just be your firmware/bios. You will have to go into your firmware/bios settings to set the boot order. I use to have a laptop that had the same problem when I ran efibootmgr. Not all system firmware/bios are created the same.

Over 12 months I had tested some 12 distros. Some I deleted to reinstall. When the number reached 20, UEFI crashed my computer when the new system requested a reboot.

I tried, using the bios, to discard old unused entries. but on saving and returning, the entries were back. Trying to change the boot order did not work, but discarding every entry ahead of the one I wanted did work.
Now I noted the following
marking the boot entries a discarded did not persist through a reboot. The ASUS bios reported no setting changes.\
So, I did the boot entry discard again, then changed a bios parameter for the led lighting (off to on).
Now the save worked, and I had freed entries. I then returned to turn off the led lighting. and cleared out all but 4 entries (only keeping one per drive).
I want to report a bug to asus, but will follow Jefro's recommendation.
Thanks to all

The boot order is empty, that is what I posted.
I tried Jefro's suggestion, but message was "I can't do what he suggests with secure boot active.
I have the bios set to "other OS", I will try resetting it to windows and see what happens, even though I only run Linux.

What exactly did you do that returned, "I can't do what he suggests with secure boot active."?


UEFI implementation if terrible at best. Most of them allow you to access the efi shell. It's a command line to manage how it should work.

Yes, some bios's are being bricked with hundreds of boot entries. I have one that I have to delete every few boots.

I bricked one with two many entries from an external drive about a year ago.

I manually created the emibootmgr entries and remembered what I did in a script.
On reboot, all was lost. (perhaps grub or Linux startup, deleted my entries)
I am not going to pursue this further as I indicated, forcing the bios to update also updated the boot list.
