PC won't boot unless I have a usb stick plugged in

Hello, I just notice that if I don’t have my usb stick plugged in, my pc will just get stuck during boot.
I’m not so sure but I think it started with the broken grub update in august, which required manual intervention.
System info

Can we see the output of sudo efibootmgr

Here you go.

It looks like you need to switch “endeavouros” to the highest priority. You can do this with efibootmgr or just go into your BIOS and change it there.

Oh, I’ll try this. Thanks!

Isn’t endeavouros already first in my boot order?

Ugh. Yes, you are right.

Can we see the output of these commands

@dalto Could it be because his grub was installed inside his USB stick? I can think of no other sensible reason for his PC to only boot when his USB is plugged in.

Oops, efibootmgr uses partition UUIDs.

We need this command.

lsblk -o name,type,fstype,size,mountpoint,partuuid 

Either that, or it is trying to mount it during the boot process.

I can also boot if I go through the boot menu and choose the endavouros drive.

Ah…that sounds like perhaps a bios/firmware issue.

What happens if you change the endeavouros to default in your bios?

Also, what happens if you pull the drive out? What is the actual error?

If I don’t have the usb stick plugged in, the only way I can boot is if I enter the boot menu by pressing F11, otherwise it just freezes in the motherboard logo.

I think in the bios setup it shows the same boot order, which is the endeavouros first.

This is exactly what happens…
