Hi,


on partition sda2 is a win10 System. This should be in boot menu / bootloader grub2. Down you find output to understand the problem. Maybe someone can tell me what to do.


Is something with UEFI / gpt wrong - got to change that? How can I do this from openSuse bash?

Welcome to LQ.

Please surround any terminal output with "code" tags which become available when you click the "Advanced" button beneath the compose/edit post window. It makes terminal output much easier to read.

If I understand your question correctly, the Windows side is not visible in GRUB. Have you tried running update-grub?

Also, what is the output this command when in OpenSUSE?

You should also make sure that os-prober is active. Check it in yast2>bootloader.

Please execute bootinfoscript, susepaste its output, and paste the resulting URL here.

This command I've send already several times. But it did not help.
grub-mkconfig -o /boot/grub/grub.cfg

os probe ist active, yes, but I think it just does not detect the win10 partition as bootable for some reason. That's the problem I guess

The combination of LVM, encryption and BTRFS makes this too complicated for me to be of much help in understanding what is happening, or not. It may be that all that is necessary to fix this is to open YaST -> Bootloader to make sure probe foreign OS is selected, then save. To force a save, some change in Bootloader is necessary. If probe is already selected, then try changing just the timeout by one second up or down to cause a save on exit.

Your bootinfoscript output shows windows boot code in the MBR of sda and sdb indicating it is a Legacy install.
The output also shows Disklabel type: dos. For windows to boot in EFI mode it needs to be on a GPT partition so given that you have Opensuse installed EFI, a Grub EFI install will not boot a windows Legacy install. Even though you have apparently created an EFI partition on sda (windows install?) it is not on a GPT drive. Why this is necessary is something you will need to ask microsoft about.

If you look at the EFI partition output, there are no EFI files for windows so even if you had a correct entry in grub.cfg, it would not boot windows. THe correct EFI file in the Grub chainloader line is: chainloader /EFI/Microsoft/Boot/bootmgfw.efi

The set root line for an EFI install of windows is generally the UUID of the EFI partition rather than something like the Grub entry:
hd0,1

Since you have windows code in the MBR of sda, you should be able to access the BIOS firmware and set that drive to first boot in the BOOT OPTIONS to boot windows, and then change it to sdc to boot Opensuse. The reason for this is the error in your installation, mixing a Legacy install with an EFI install.

I don't usee LVM or btrfs so I don't know what impact that would have.
