Hello.

On dualboot laptop (OS 42.3 and Windows 10)

One ssd (sda) 120G with 10 partitions (GPT).
Partitions that have nothing to do with the question are not mentioned.

One HDD (sdb) 1TB with 19 partitions.

Using clonezilla, I have made 2 images kept on separate usb stick :

  • one for the linux part : sda8, sdb1, sdb2, sdb12
  • one for the windows part : sda1, sda2, sda3, sda4, sda5, sda6

Recently I had had problem and have to restore the linux part.
I could not repair the system.
After restoring the linux image (sda8, sdb1, sdb2, sdb12) , the system does not boot.

Is there more to do in that situation, to restore the system ? ( linux or windows )
Is it necessary to keep the partition tables separately and restore them before restoring linux or windows ?
When restoring one system from one image, does the partition table restored ?

Any help is welcome.

And happy new year.

A quick guess: the numbering of the devices does no longer align with the actual situation on disk.

Exactly what happens when you try?

It’s a really poor idea to have two UEFI partitions in the same PC. The openSUSE installer may insist you need a second one, but you shouldn’t let it. You should ignore its asserted errors and insist on only using the one originally created for Windows, unless your HD is larger than 16TB and uses 4k sectors both logically and physically, which I’m not sure is even supported yet. All booting from UEFI systems should be done from the same ESP partition. Trouble eventually ensues configured otherwise.

I try to elaborate my problem :
First of all, all data are backup separately. So no need to backup them specifically.
Now restoring system is time consuming. So the idea is to backup each system ( can be multi-boot with or without windows (all flavor) ) and restore only the failed system.
On a single operating system there is no problem.

That is what I did after a real crash on a test laptop.

I have looked what is the contents of clonezilla backup ( partitions to image ).
There are files that describe what partitions are.
I have just imagine that during the restore only the partition(s) contained in the image is(are) update or rewrite.
Leaving the rest unchanged.

Is it possible to restore only the failed system.

And Happy new year.

side note : I have restored the initial state of the computer.
