[Bug 1926865] Re: During OS install, GRUB tries installing on sda even when it should install on sdb

[Mark A Gerads]

The log files are from my own computer, not my dad's; I used the ubuntu-bug command to report this bug.
During install, I noticed the installer run "grub-install /dev/sda" right before the installer failed. This happened twice, as I had tried installing Ubuntu to my dad's laptop twice.

Title:
  During OS install, GRUB tries installing on sda even when it should
  install on sdb

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  I tried installing Ubuntu on my dad's laptop, but the installer failed to install GRUB.
  I noticed it was trying to install GRUB on /dev/sda even though the EFI partition and the Ubuntu root partition were both on /dev/sdb
  I suggest that instead of hard-coding the Ubuntu installer to install on /dev/sda, the Ubuntu installer should dynamically detect the drive which has the EFI partition and install GRUB on that drive.
