[Bug 1933637] Re: Installer crashed(Executing 'grub-install/dev/sda' failed)

[haraldthi]

Installing on a dual-boot system. Three partitions and a swap:
sda4: / (64 GiB ext3)
sda5: /usr (64 GiB btrfs)
sda6: (64 GiB swap)
sda7: /log (64GiB btrfs)

Most of the Windows 8 insatllation sits 0n sdb, but there's a data partition and some boot partitions as well:
sda1: EFI system partition (67.5 GiB fat32)
sda2: Microsoft reserved partition
sda3: Basic data partition (65,8 GiB ntfs)

I am making a reinstall of my system due to a corrupted disk, and have copied the contents of the Windows partitions over to this new disk with GNU ddrescue.
Sda8 contains my home partition, and is best left untouched so far. Actually, it would be great if you could mount data partitions like /home during *without* destroying all the data that sits there, as I forgot that little detail (not having done any installs in quite a while) and have to do quite the rescue job.

Title:
  Installer crashed(Executing 'grub-install/dev/sda' failed)

Status in grub-installer package in Ubuntu:
  Confirmed

Bug description:
  The installation was going quite smooth. I'm dual-booting with
  Windows. I had created three partition

  /boot - ext4 - 2GB
  / - ext4 - 400GB
  swap - 4GB
  EFI System Partition - 100MB

  For the rest of the steps, I was choosing default options.

  #Update
  Just FYI: After partition confirmation dialog, the next screen is for selecting timezone. I went back to the partition screen from the timezone screen. 


  I was recording the whole installation process. Let me know if any
  other piece of information is required. :)
