[Bug 1742061] Re: failed grub installation

[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:
  failed grub installation

Status in grub-installer package in Ubuntu:
  Invalid

Bug description:
  Installed on Lenovo Ultrabook U410. Already suceeded before with standard installation on main HD
  I partitioned the internal 32G SSD as 8G swap as logical partition at the end and remaining for / at the beginning as Primary partition. 
  I partitioned the main 750G disk to have 120G for /usr, 120G for /opt and the remaining 500+G for /home, all as logical partitions.
  All went fine until the end but grub did not install as the installer reported.
  Trying now with some manual fixes.
