[Support] UEFI boot order changed when booting into windows

First off, sorry if this isn't quite the right community, I did try posting on !pop_os@lemmy.world 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
  
  You’ll need to find the partition number and the reference to the disk in /dev for your boot partition /dev/disk/by-partuuid/172a0183-3a89-4b78-b1b3-d016ca6675f7. You can try using ls -l /dev/disk/by-partuuid/172a0183-3a89-4b78-b1b3-d016ca6675f7 to see where it points (i.e. for /dev/sdb2 you would use --disk /dev/sdb --part 2).
  
  I also, get this error "invalid numeric value Y" when trying to manually register systemd-boot

  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 UUID
  
  sometimes 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 command
  
  Thanks for explaining, I’m still quite new to Linux in general
