1. Start with a livefile system, like Knoppix, GRML; Trinity Rescue Kit,. whatever. 2. Mount the root partition. 3. Now you can edit the "/etc/shadow" file on this partition. Look for the user "root" and delete everything between the ":" and the "0". The entry should look like "root::0:99999:7:::" 4. Reboot, now you should be able to enter as root without password. (If I made a mistake here, someone might correct me, as I did this thing alt last almost 4 years ago!) The other option is, to search for a boot disk called "Kon-Boot". Booting from this letts you in EVERY system (Windows, linux etc.) without password. There is also the option (I never checked), to enter "#!/bin/bash" at the boot prompt, this let you in a console with admin rights. Never checked this, too. However, there are good documents of these in the web, but I was too lazy to look for them. Google will help you. Question, can you login as a normal user? Can you sudo to root? (I am no friend of sudo, so I disabled this option. Does stretch enable this by default?) If so, you will not be able to login as root (as far as I know), but login as normal user, then "sudo su" and root password will let you in. Hope my (not proven) hints help either.
