I have Tumbleweed 32-bit installed in an external drive. And I have it setup so that it can boot with legacy mbr booting, with 32-bit efi booting and with 64-bit efi booting. Yesterday, I connected the external drive to a system with 64-bit efi booting, but with secure-boot disabled. And the Tumbleweed 32-bit system would not boot. It used to boot. So I reverted grub2-x86_64-efi back to version 2.04-16.1 (the version just before the update around Sept 15th). And after going back to the old version, I can now boot it again with 64-bit efi. By the way, to install x86_64-efi boot support, I use: grub2-install --target=x86-64-efi --removable -no-nvram For further testing, I have setup a VM with Leap 15.2 and Tumbleweed 32-bit installed side by side. In the Leap install, I used version 2.04-lp152.7.12.1 of grub2-x86_64.efi so that it can boot Tumbleweed. Or I can directly use the grub2 boot code installed from Tumbleweed (version 2.04-16.1) to boot either. Creating that VM was tricky, because of bug 1177849 -- You are receiving this mail because: You are on the CC list for the bug.
