I created an image of debian 7 on an SSD disk and later restored it on another computer with excatly same type of SSD disk. 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 plenty of times before on older computers and it usually works fine. These computers has EFI, could this be the issue? Any ideas, or workarounds?

Thanks

Do you use MBR or GPT on SSD? Possibly you will need to switch between UEFI/LEgacy boot mode as shown here: https://phoenixts.com/blog/uefi-vs-legacy-bios/
