[Bug 910907] Error occured while trying to install GRUB2 UEFI bootloader

Created attachment 618758 [details] new yastlog.
This is a new Yastlog. Note there is no error during the run of the yast boot loader. But it is not possible to boot openSUSE 13.2 using EFI.
Several cases have been tested among distinct BIOS setup parameters values:
1- Secure Boot set to Enable ==> no GRUB2 menu, boot starts automaticaly Windows 8.1
2- Secure boot set to Disable, startup with UEFI set to Only ==> no GRUB2 menu, boot starts automaticaly Windows 8.1
For debugging above two issues, we need "efibootmgr -v" output from openSUSE or any other linux distribution. I guess that Windows is on default UEFI path thus booted automatically. Did you try to interrupt the boot process for UEFI boot selection and do you see openSUSE listed in that menu?
3- Secure boot set to Disable, startup with UEFI set to Both ==> GRUB2 menu starts, OpenSUSE can boot but when selecting Windows Boot, GRUB2 cannot start Windows and it crashes.
It looks to me that "Both" is "legacy+UEFI" and is possible that it tried to boot from legacy path. It depends on your disk's history and may work incidentally. While grub booted, could you please type 'c' to enter command mode and paste to output of 'set' command here to make sure that the grub image is uefi ? Thanks. -- You are receiving this mail because: You are on the CC list for the bug.
