[Bug 1581836] Re: Incomplete 16.4 install from DVD image

[Michelet]

"recommended performing a bios mode install instead" : the message was
unclear to me, it seemed to me that the installation was either in EFI
mode or aborted. Anyway, I installed using the entire disk afterward and
indeed the problem was solved. Thanks for looking at the problem, it
might help somebody.

Title:
  Incomplete 16.4 install from DVD image

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Trying to upgrade to 16.4 version (previous one was probably 14.x).
  Internet update failed (on a black screen - had to reboot by hand).
  With an install disk the installation keeps sending bug reports (third
  try, the problem seems not to be at the same point). After reboot
  (thought there has been an error message) the system *seems* OK but I
  still have problems to read my DVD collection (which is why I keep on
  trying to reload the upgrade). I'll try again in a day or two...
