First off, sorry if this isn’t quite the right community, I did try posting on [email protected] but didn’t get a solution. You can see that post here
I have my computer set up to dual boot pop!_os and windows on separate drives. I have my UEFI set up to boot into pop OS and I use systemd-boot to load windows, however after booting to windows and restarting my UEFI boot preferences are changed so Windows boots first instead of pop os.
I have fast boot and secure boot turned off in the bios and fast boot turned off in windows. How can I prevent this?

I’m a little confused about what I’m meant to be doing in this part
I also, get this error “invalid numeric value Y” when trying to manually register systemd-boot
The weird long /dev/disk/… I used comes straight from your Pastebin. It’s a unique link to the your EFI partition, but sadly
efibootmgr
can’t use that to register your bootloader. The Arch wiki example command leavesX
andY
for you to fill in, and you need to find theX
andY
for your system to make it work. They’re different for every computer so I can’t tell you what they are.On my system, the EFI partition is
/dev/disk/by-partuuid/2fbab938-cc71-407a-996a-874d4486fca8
. I used thels
command to find the right information in my example above, butrealpath
is probably better, so I’ll use that in this comment.I can find out the right
X
andY
for my system using the following command:user@ desktop ~ $ realpath /dev/disk/by-partuuid/2fbab938-cc71-407a-996a-874d4486fca8 /dev/sde1
As you can see,
/dev/disk/by-partuuid/2fbab938-cc71-407a-996a-874d4486fca8
actually points to/dev/sde1
. That means my disk (“X”) issde
and my partition number (Y) is1
.What this means in my case is that I would need to issue the following command to register
systemd-boot
:sudo efibootmgr --create --disk /dev/sde --part 1 --loader "\EFI\systemd\systemd-bootx64.efi" --label "Pop_OS" --unicode
Notice how I filled in the
e
forX
in/dev/sdX
and1
forY
.After running the registration command, I get the following output:
BootCurrent: 0014 Timeout: 1 seconds BootOrder: 0004,0003,0000,0015 Boot0000* Windows Boot Manager Boot0001 Hard Drive Boot0002 USB KEY Boot0003* ubuntu Boot000E Hard Drive Boot0010 USB KEY Boot0015 Hard Drive Boot0004* Pop_OS
Ignore all the weird device names, my motherboard injects those into the configuration. The important part is that my computer’s boot order is
0004
(Pop_OS),0003
(ubuntu),0000
(Windows Boot Manager), and lastly0015
(a random hard drive). This is the order of bootloaders my computer will try before throwing up a “no bootable device” error. The asterisks next to the name indicate that they’re enabled somewhere in the boot order.These numbers will look different on your computer. What you’ll probably want to do, is copy the bootorder as listed by the command that added the
Pop_OS
boot entry and add the number of your new bootloader in front.Suppose I want to change my system to try to boot
Pop_OS
first, thenubuntu
, thenWindows Boot Manager
. I can do that without booting into my BIOS through the following command:sudo efibootmgr --bootorder 0004,0003,0000
You can pick any order, but I would advice not removing any unless you know what you’re doing.
I understand now. I now have a pop OS boot entry, and it’s set as first boot priority. However, I’m still having the original issue of windows putting itself first on the boot priority after rebooting from windows.
Edit: after another reboot the pop_os boot entry I just made has vanished

Could updating my bios and all that help with this issue?

lsblk -o NAME,SIZE,MOUNTPOINTS,UUID
try this command, it will show you what partitions you have on the machine then modify previous command with correct labels and UUIDsometimes you need to modify the command
sudo efibootmgr --create --disk /dev/sdX --part Y --loader “\EFI\systemd\systemd-bootx64.efi” --label “Pop_OS” --unicode
/dev/sdX --part Y needs to be replaced with correct labels for partitions, If you are lost just paste the output of the
lsblk -o NAME,SIZE,MOUNTPOINTS,UUID
commandThanks for explaining, I’m still quite new to Linux in general
