Dual Boot

English Install/Boot/Login

I’ve dual booted Win 10 & Tumbleweed for ages now, rarely use Windows, bit of a novelty. However upon updating 10 it has steamrollered over my boot priority, the big I am. I have to use F12 temporary boot menu to boot SUSE. The boot priority menu in BIOS just freezes on me for some reason. Do I just need to reinstall GRUB? It would be handy to know for the future. Both Win & SUSE are hard partitioned with SUSE on a secondary M.2 SSD. Tumbleweed just took care of everything automatically when I installed, seamless, but now messed up by Windows!

If you can get into linux via F12, and assuming that this is a UEFI box, then something like

# efibootmgr -v
# efibootmgr -o 3,1

might fix the problem. The first of those just lists the UEFI boot options. The second command sets the boot order. The command that I suggested would make boot 0003 the first and boot 0001 the second. Use the output from the first of those commands to find what numbers you need in the second.

Well now, that was simple!
