http://bugzilla.opensuse.org/show_bug.cgi?id=1182592 http://bugzilla.opensuse.org/show_bug.cgi?id=1182592#c3 --- Comment #3 from Felix Miata (offline until ???) <mrmazda@earthlink.net> --- Created attachment 846589 --> http://bugzilla.opensuse.org/attachment.cgi?id=846589&action=edit y2logs.tgz from another 15.3-20210207 DVD .iso installation on comment 0 UEFI Haswell PC I repeated a similar installation from DVD 20210207 iso, without enabling online repos, on comment #0 PC. Again, I elected to allow updating NVRAM, and "Boot0000* opensusetw" on sda1 was replaced with "Boot0000* opensuse" on sda21. Again, first attempt to boot failed with same message as in comment #0: [quote]Welcome to GRUB! error: ../../grub-core/commands/search.c:296:no such device: eb73...a77b. error: ../../grub-core/kern/fs.c:121:unknown filesystem. Entering rescue mode... grub rescue> help Unknown command -help'. grub rescue> _[/quote] I was able to fix this by booting the following Boot0004* into TW: #efiboomgr BootCurrent: 0000 Timeout: 0 seconds BootOrder: 0000,0004,0005 Boot0000* opensuse Boot0004* UEFI OS Boot0005* UEFI: SanDisk This I repaired with efibootmgr, /etc/default/grub changes (to GRUB_DISTRIBUTOR="opensuse153"; and rearranging GRUB_CMDLINE_LINUX_DEFAULT=), then updated bootloader with YaST2, to result in: #efiboomgr BootCurrent: 0000 Timeout: 0 seconds BootOrder: 0001,0000,0004,0005 Boot0000* opensusetw Boot0001* opensuse153 Boot0004* UEFI OS Boot0005* UEFI: SanDisk after which booting from the new 15.3's sda21 ESP proceeded as expected. Possibly relevant partitions were as follows: # parted -l ... Disk /dev/sda: 512GB Partition Table: gpt ...

Formatted EXT2 on sda22 was set to mount on /boot. Formatted EXT4 on nvme0n1p2 was set to mount on /. All other partitions partitions were ignored. Again I did not enable os-prober. -- You are receiving this mail because: You are on the CC list for the bug.
