My (64bit) system upgraded from Ubuntu 16.10 to 17.04. After the upgrade I restarted the system but the system will not boot. The only thing displaying on the screen is 'ad address'.

Any idea what went wrong and how to fix this? Boot-rescue? Download and re-install from CD?

  • Can you edit your question and add a picture of the screen?

  • Sorry no. The problem was sorted before you asked for the screenshot. Basically at the very beginning of boot-up the screen would be black with 'ad address' written on the first line. Apr 26, 2017 at 21:01

  • Finally got the boot repaired after the second try with Boot-Repair. I have no idea what went wrong, but from what I can sea by scanning the info, is that Grub found Windows 7 on my external drive which I had forgotten to remove before the upgrade. Somehow the MBR got corrupted, since on the 2nd run of Boot-Repair (after I removed the external harddrive) I could see it mentioning 'repairing MBR'. After this run the laptop finally booted. The link to the first boot-repair info is: paste2.org/1GJ1LgCG. Apr 25, 2017 at 19:41
