I created an image of debian 7 on an SSD disk and later restored it on another computer with excatly same type of HW. however I'm getting the error message:
No bootable device -- insert boot disk and press key
The image was created using a live OS with the command:
dd if=/dev/sda conv=sync,noerror bs=64K | gzip -c > backup.img.gz
And later restored to disk with:
gunzip -c backup.img.gz | dd of=/dev/sda
I've done this before on older computers and it usually works fine. If i restore the image on the computer i created from it seems to be working.
These computers has EFI, could this be the issue? Any ideas, or workarounds?
