Title:
  installing ubuntu 18 crashes

Status in grub-installer package in Ubuntu:
  New

Bug description:
  I had a dual boot installation. Ubuntu 16 alongside Windows 10.

  Since a few months I wasn't able to install any new software or update
  already installed, in Ubuntu. Anytime I tried to do so, disk started
  to be 100% busy and system became unresponsive.

  Now I tried to install Ubuntu 18 on top of Ubuntu 16, and got this
  error that GRUB sector cannot be edited/formatted/written.
