lately i have tried to restore a linux mint 17.2 backup without luck using alternative stable releases - 20150805-vivid.

the filesystem of the ssd is gpt and it is an uefi installation. partitions as follows:

esp
boot
root
home

i chose esp, boot and root to be restored. the process went fine, but after restarting, i was prompted 'os can not be found, install an os'. i then booted gparted and partition table looked fine, except that the flags of the partitions were missing?

i am new to linux, but not to clonezilla, so i wonder if there is some extra settings to take, in order to create and restore a linux backup without issues?

hope you have some tipps for me.

So you use "restoreparts" to restoat the image? Not "restoredisk"?
If so, normally the efi boot manager won't be processed. Therefore you have to manage the EFI boot manager by yourself.
There is a program on Clonezilla live called "update-efi-nvram-boot-entry" which is used to be process this. You can also try to use that. For more info, run
update-efi-nvram-boot-entry --help

yes, i used restoreparts but left out /home, so to see if everything will go fine just in case. with my old uefi win setup this worked fine. i could restore the efi relevant partitions without a problem.

i have to add that i have permanently turned off fast+secure boot in uefi-bios.

ok so if i understood you correctly, clonezilla only makes changes in the uefi boot manager after restoredisks (with update-efi-nvram-boot-entry)?

concerning this nvram update, if this is normally not needed after doing restoreparts, i better leave it untouched.

will reinstalling just the efi + boot partition via the mint usb stick also be a valid option (although this would question the whole purpose of restoring images)?

" clonezilla only makes changes in the uefi boot manager after restoredisks (with update-efi-nvram-boot-entry)?" -> Yes.
"will reinstalling just the efi + boot partition via the mint usb stick also be a valid option" -> Maybe. I have never tried to do that via Mint USB stick. If you test it, please let us know the results.
Thanks.

hello steven,

i just wanted to let you know that restoreparts also makes changes to the boot entry.

at least, i noticed a yellow text message after restoring just the esp + boot partition of my backup:

running: update -efi-nvram-boot-entry -r

adding boot entry in nvram

Thanks for reporting this. This has been fixed in Clonezilla live >= 2.4.2-59 or 20151016-*:

http://clonezilla.org/downloads.php
Please give them a try.
Thanks.

Steven.
