@Davidj-0

still doesnt want to boot with ether two of the disk or bath check as bootable
from what I know of the disk with my previous try, it just a partition without anything, not even a mrb.

Ok so after a long week on other problems I can get back to my migration issue.
I'm trying to boot from a live environment to add grub, but it just plain tell me that there is no bootable device...

@TeddyAstie thx a lot,
apart from installing grub on the disk, is there anything else to do ?

Hello,
I'm trying to migrate vm from an old linux xen server 4.4 to a new server and use the xen2xcp (https://github.com/xcp-ng/xen2xcp) script provided for that. I've also copied the vmlinuz and initrd into /boot/gest.
But when I start the vm, it refuses with the error :

xcp-ngFailed: Internal error: xenopsd internal error: VM = 6813d025-efa3-e52a-6069-d6defaba14f7; domid = 2; Bootloader.Bad_error No kernel found in

So I guess the vm don't recognize the kernel and ram disk but why ? and how to fix it ?
