No boot after desaster recovery in UEFI Bootmode

Post by MaVo66 »

Hello experts! I have a small problem with disaster recovery using the current Linux agent and recovery medium 6.3.2.1207_x86_64:
When I back up and restore a physical (HPE Proliant Gen9) SUSE Linux Leap 15.6 server in ‘Legacy Boot Mode’, it works perfectly and as described in the instructions. However, if I back up an identical server in ‘UEFI’ boot mode, the server boots into a ‘grub’ prompt after recovery.
If I understand the posts in this forum correctly, the grub loader must be recreated manually. Does anyone have (preferably simple...) instructions on how to do this?

Hello Marcus,

After performing a BMR (Bare Metal Restore), you must manually create a new EFI boot record.
  • Exit to Shell after restore.
  • Mount EFI Partition, example:

Code: Select all

mount /dev/sdX1 /any_mount_point
  • Find Boot File (use shimx64.efi or grubx64.efi, if you have only it):

Code: Select all

ls /any_mount_point/EFI/<YOUR_DISTR_NAME>/
  • Create Boot Entry:

Code: Select all

efibootmgr --create --disk /dev/sdX --part 1 --loader /EFI/<YOUR_DISTR_NAME>/<boot_file>.efi --label "Linux Boot"
--disk /dev/sdX: The disk containing the EFI partition.
--part 1: The partition number of the EFI partition.
--loader: Path to the EFI boot file.
--label: A name for the boot entry.

If you still encounter issues, please open a support case and share the case number here for reference.

Thank you for your prompt response. However, after successfully completing the restore, I am not directed to Linux, but rather to ‘GNU GRUB version 2.12’ with the prompt ‘grub>’.
How can I execute the suggested commands from here?

Hello,

Just boot again with Veeam Recovery Media ISO, then exit to shell: https://helpcenter.veeam.com/docs/agent ... _files.png

Since Linux is relatively limited on the boot image, is there any documentation on how to perform the suggested operations?
