That could be it. The drive originally had a working wheezy installation that booted properly and worked just fine. I then decided to upgrade this working wheezy installation to testing/stretch, just to see how it would go. It did not go too well, so I decided to revert back to wheezy by restoring the data from my backup drive. The /boot partition was restored by dd-ing the data from /boot partition of the working backup drive (/dev/sda1): # dd if=/dev/sda1 of=/dev/sdb1 conv=sync,noerror // Can you see the GRUB version which boots ? When booting, GRUB immediately drops me into the "grub rescue" mode. I did not see any version number nor I found any way to check the version number from "grub rescue" mode. Thanks
