FLVAL · November 5, 2020, 2:10pm

0003 is not active, remove it also, it’s the same than 0008

efibootmgr -b 3 -B

jackmoloko · November 5, 2020, 2:11pm

i did like this:
efibootmgr -b 0004 -B
without sudo

FLVAL · November 5, 2020, 2:12pm

look UP

efibootmgr -b x -B and not efibootmgr -b xxxx -B

Boot0001* EndeavourOS HD(1,GPT,5f774f65-6102-4e95-9fe0-06fb49f7d6e1,0x800,0x96000)/File(ࠜEFIEndeavourOSgrubx64.efi)

Looks like you missed some \ : EFIEndeavourOSgrubx64.efi >> \EFI\EndeavourOS\grubx64.efi

If
sudo efibootmgr -c -d /dev/nvme0n1 -p 1 -w -L EnOS -l “\EFI\EndeavourOS\grubx64.efi”‘’
doesn’t get it right, remove the “quotes” and try again.

Looks again that \ are missing. I don’t know why.

FLVAL · November 5, 2020, 2:25pm

It’s still not good with the link on 0001 and 0002 !

We have to obtain File \EFI\EndeavourOS\grubx64.efi and not FileEFIEndeavourOSgrubx64.efi
I believe is due to the double quote " that couldn’t get the antislash \ then try it with simple quote '

like this:

sudo efibootmgr -c -d /dev/nvme0n1 -p 1 -w -L EnOS -l '\EFI\EndeavourOS\grubx64.efi'

pebcak · November 5, 2020, 2:27pm

This

Yes, and 0002 as well.

remove the 0002 now and you are ok

efibootmgr -b 0002 -B

Looks good!

jackmoloko · November 5, 2020, 2:34pm

Before rebooting do I need to do this grub2-mkconfig -o /boot/grub2/grub.cfg?

FLVAL · November 5, 2020, 2:35pm

Before to reboot remove 0002 then update grub, it doesn’t kill a rabbit !
Show us before reboot to be sure…

pebcak · November 5, 2020, 2:38pm

If you want EnOS’s Grub to be in charge of the booting the other OS’s, then you need to run this when you boot into EnOS as well.

By the way, welcome to the forum and good luck with your endeavour.

jackmoloko · November 5, 2020, 2:38pm

What exactly needs to be shown?

FLVAL · November 5, 2020, 2:39pm

efibootmgr -v

jackmoloko · November 5, 2020, 2:40pm

This is exactly what I want, please tell me how to do it !!! ???

pebcak · November 5, 2020, 2:42pm

From your efibootmgr -v, it looks you got both the boot entry and the boot order right. I would just reboot the system and boot into the EnOS and update it’s grub there.

When you want to change order just use like this:

efibootmgr -o x,x

Everything is ok, so reboot to see what we got !
This will tell that your next reboot would be on 0001 EnOS in your example:

efibootmgr -n 1
