http://bugzilla.opensuse.org/show_bug.cgi?id=1190874 Bug ID: 1190874 Summary: grub restore only allows boot from 1 partition Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: 64bit OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Bootloader Assignee: screening-team-bugs@suse.de Reporter: tech@reachthetribes.org QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- This was first brought up on this forum thread: https://forums.opensuse.org/showthread.php/560223-grub-restore-only-allows-b... I have 2 partitions of equal size on my laptop, about 26gb each, ext4 format. They are both used for a root partition, the idea being to have one as a backup in case one of the tumbleweed updates totally doesn't work. This is my partition setup: Device Start End Sectors SizeType /dev/nvme0n1p1 2048 1026047 1024000 500M Microsoft basic data /dev/nvme0n1p2 1026048 55711743 54685696 26.1G Linux filesystem /dev/nvme0n1p3 55711744 110397439 54685696 26.1G Linux filesystem /dev/nvme0n1p4 110397440 1943756799 1833359360 874.2G Linux filesystem /dev/nvme0n1p5 1943756800 1953523711 9766912 4.7G Linux swap When I run the procedure to restore/install grub, here is what I do. As root in a terminal: ---

mkinitrd grub2-mkconfig -o /boot/grub2/grub.cfg Generating grub configuration file ... Found theme: /boot/grub2/themes/openSUSE/theme.txt Found linux image: /boot/vmlinuz-5.14.5-1-default Found initrd image: /boot/initrd-5.14.5-1-default Found linux image: /boot/vmlinuz-5.14.2-1-default Found initrd image: /boot/initrd-5.14.2-1-default Warning: os-prober will be executed to detect other bootable partitions. Its output will be used to detect bootable binaries on them and create new boot entries. Found openSUSE Tumbleweed on /dev/nvme0n1p3 Adding boot menu entry for UEFI Firmware Settings ... done grub2-install /dev/nvme0 Installing for x86_64-efi platform. Installation finished. No error reported.

Notice what the result is in the grub configuration file. I will leave out the advanced options on both partitions because they are the same with regard to what I found: --- ### BEGIN /etc/grub.d/10_linux ### menuentry 'openSUSE Tumbleweed' --class opensuse --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-ba22e191-xxxxxxxxxxxxxxxxxxx' { load_video set gfxpayload=keep insmod gzio insmod part_gpt insmod ext2 search --no-floppy --fs-uuid --set=root ba22e191-xxxxxxxxxxxxxxxxxxx echo 'Loading Linux 5.14.5-1-default ...' linuxefi /boot/vmlinuz-5.14.5-1-default root=UUID=ba22e191-xxxxxxxxxxxxxxxxxxxx splash=silent mitigations=auto quiet echo 'Loading initial ramdisk ...' initrdefi /boot/initrd-5.14.5-1-default } --- --- ### BEGIN /etc/grub.d/30_os-prober ### menuentry 'openSUSE Tumbleweed (on /dev/nvme0n1p3)' --class opensuse --class gnu-linux --class gnu --class os $menuentry_id_option 'osprober-gnulinux-simple-4efad914-xxxxxxxxxxxxxxxxxxxxxxx' { insmod part_gpt insmod ext2 search --no-floppy --fs-uuid --set=root 4efad914-xxxxxxxxxxxxxxxxxxxxxxxx linuxefi /boot/vmlinuz-5.14.2-1-default root=UUID=ba22e191-xxxxxxxxxxxxxxxxxxx splash=silent mitigations=auto quiet initrdefi /boot/initrd-5.14.2-1-default } --- See how on the 2nd menu item in grub for my 2nd root partition, the menuentry line points to the right UUID for that partition, and the search line also points to the right UUID for that partition. However, the actual boot line that begins with linuxefi points back to the other root partition, the same as in the first menu entry in grub. -- You are receiving this mail because: You are on the CC list for the bug.
