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 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!
