[Support] UEFI boot order changed when booting into windows

rickywithanm@aussie.zone to Linux@lemmy.ml – 41 points –

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?

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 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.

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

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

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

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!
