[Bug 1740539] Re: grub unable to launch after install

[Phillip Susi]

Your disk is currently partitioned to boot in bios mode, but you booted
the installer in EFI mode. A warning message prompted you that this
could be a problem and recommended performing a bios mode install
instead, but you chose not to. You either need to perform the bios mode
install, or partition the disk using GPT and set up an EFI system
partition to install in EFI mode. This will be done for you if you
choose the "use entire disk" guided install option.

Title:
  grub unable to launch after install

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  After several trials to install ubuntu 16.04.3, a message appeared informing that the grub package was unable to launch, and so the installer failed. 
  But earlier, I had tried my flash drive with the function "check my disk" on Ubuntu frontpage, and it said everything is OK, 
  Every try failed at the restarting moment, so I tried the fourth time in a different way and install ubuntu next to the remains of the previous try,
