[opensuse] very annoying grub2 issue, Leap 15.0 / windows 10
Hi guys, I have a extremely annoying issue with grub2, or more precisely grub2-once. I have two systems that both run a dual boot setup between Leap 15.0 and Windows 10. Both boot from UEFI with secure boot turned OFF. One of them i can choose what to boot next from the command line with grub2-once <number>, and it works just fine: I do "sudo grub2-once 3; sudo systemctl reboot" and I end up in windows, and on next reboot I get my grub menu again The other one, whenever I do the same sequence of "sudo grub2-once 3 ; sudo systemctl reboot" I bot into windows, but then I keep booting into windows - grub2 is not working anymore so the boot sequence defaults to the original windows bootloader... The only differences between the two systems that I can think of are: the working system has one harddisk, the nonworking one has two harddisks (but none of the actual OS installed on the second disk, in both windows and linux) the working system has windows 10 home, the broken one has windows 10 pro any ideas/hints?

normally (but this depends heavily on the computer model), you can boot either system from the Firmware (uefi) boot menu and choose the default from the setup menu jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I'll guess. The one that is not working is using "btrfs" (for the file system containing "/boot"). The working one is using a different file system. I'll note that I use: # efibootmgr -n 1 when I want to next boot Windows. Here, it is Windows 8.1, and the output from # efibootmgr -v shows that boot entry 0001 is the entry for Windows. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

nope, no btrfs involved in any of my systems. I use ext4 for everything, lvresize -r -L -25% is just too cool to pass.

Gotta try that one... Cheers MH -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

...that works. yay is me. ...ok, i'd still like to know why grub2-once works on one system and doesn't work on the other, but for now I'm happy with efibootmgr.
