Like so many I didn’t read the release notes and upgrade to v25. Now my VM is gone and I am trying to get it back with the manual migration instructions
Created a new machine used the ‘old’ storage and now the vm doesn;t want to boot. When I go into the bootmanager I can see a EFI folder with the grub.efi but it doesn’t start. Machine was installed with Debian 12.
I know upload an Ubuntu live image and when I boot that, I can see all the data is there, but how can I restore the boot process, so that is starting agian without having to reinstall the vm
It is normal that after the update to 25.04 and migrating the VM, grub does not start the system as it used to. From my understanding launching the grub.efi makes grub launch grub again. When booting from file you should encounter a file structure like this/boot/efi/EFI/debian
In this folder there should be the following files:
BOOTX64.CSV fbx64.efi grub.cfg grubx64.efi mmx64.efi shimx64.efi
Try selecting the shimx64.efi
. This should boot debian if there is no other problem.
added all the efi files and now its booting.
Tip for other users. The shell and serial console doesn’t show anything on my side. I added the vnc option and there was my login prompt visible.
