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

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

Change boot order in UEFI and then save your changes. It did the trick for me last time windows screw me over

That's what I'm doing, but it gets changed again every time I boot to windows

Hi I am not a linux pro, but for me a quick fix what worked was to disable Windows boot. basically everytime windows boot it puts itself as priority, but cannot any more this way. I would then use the grub menu at boot to select what os i needed. I use mint but since both are based on ubuntu should work in the same way. found this online, more or less what i did: https://unix.stackexchange.com/questions/241809/grub2-gone-every-time-i-boot-windows-10 https://unix.stackexchange.com/questions/68581/how-can-i-prevent-windows-from-overwriting-grub-when-using-a-dual-boot-machine

My solution to this was to just set the boot order how I wanted it and then lock it from BIOS

My solution years ago when windows used to do this to me with a dual boot was to move windows to a virtual machine instead, which works great for me!

Would recommend as much ram as possible though. I find performance great with 16gb of ram to share between host and the vm.

Windows updates would often mess up boot prior to me switching. Very annoying.

[-] danielton@lemmy.world 1 points 1 year ago

What VM software would you recommend? The issue I always run into is GPU acceleration whenever I use the usual virt-manager or VirtualBox.

[-] ebits21@lemmy.ca 1 points 1 year ago

Virt-manager is my preferred but I only have integrated graphics anyway.

I had a similar issue, and no changes made in Linux would stick. Bootice is a Windows program that allows you to make changes in UEFI boot order and was the only solution that worked for me. Good luck!
