Dear all,
So, i try to write back a backup that i took about half a year ago. I run LUbuntu 24.04 LTS.
I use with clonezilla-live-20250303-oracular-amd64 and let it check the backup before writing it back without errors.
Then i start writing back the backup "using the partition table from the image". In the end the full command is:
/usr/sbin/ocs-sr -g auto -e1 auto -e2 -r -j2 -c -k0 -plu -p choose restoredisk historyLU-02_all_working smb ['historyLU-02_all_working' is the name of the backup]
The disks are at this time:
sda: clonezilla bootdevice
sdb: target to which the back should be written back
sdc: where the clonezilla-backup is located
Obviously the original bootdisk was sdc when the backup was done, because clonezilla says:
"Target disk sdb does not exist in the saved image from disks(s) "sdc"
///Note/// If the restored OS is GNU/Linux, you might have to modify /etc/fstab and grub config file in the restored GNU/Linux to affect these changes so that it can boot successfully!"
the layout should be:
sdb1: swap
sdb2: LUbuntu
sdb3: bios_grub
When I then start the computer, the BIOS messages show as normal and then the computer resets, the BIOS messages show again and then the screen gets black. Obviously there is a video signal (otherwise my monitor complains about a missing signal). I cannot get anything, also no terminal with the CTRL/SHIFT/ALT F2 combinations.
Can somebody make heads and tail of it? I only have a very basic understanding of Linux. It sounds as if I have to edit GRUB but am a bit clueless about it...
"When I then start the computer, the BIOS messages show as normal and then the computer resets, " -> Maybe you can take a video and share with us? It's easier for us to understand that.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
update: it is fixed!
I was searching the internet a bit and heard of the "Boot Repair Disk". It can be found at: https://sourceforge.net/projects/boot-repair-cd/
It sounded promising and it worked wonders! It is a huge download (the iso file is 2.6 GB), is a live CD and needs internet connecting during its reapir. As far as I saw, it wipes GRUB, gets info of the disks and then reinstalls GRUB with the correct settings.
And after the repair, the computer boots again! This now goes to the lifesaver tools that I have :)

all help highly appreciated :)
PS: I also tried to ssh in when I just see the black screen: no connection
PPS: the log files from clonezilla can be found here:
