[Bug 1805876] Re: BTRFS-Install; separate home-partition; dual-boot; grub-efi fails

Thu Nov 29 17:42:53 UTC 2018

** Description changed:

  Ubiquity fails to install Grub on existing ESP (EFI-System-Partition)
  for Dual-Boot of Ubuntu Bionic 18.04 Release to existing Windows 10
  Professional.

  Disk is a 320GB HDD SATA, GPT, EFI System Partition and an existing
  Windows-Partition.

  Installed Ubuntu 18.04 for / on BTRFS, plus a separate /home on BTRFS.

  Just for the sake of completeness, tried to install Cosmic, Yakkety,
  Xenial and Trusty in exact same manner and they all do complete.

  Reproducible for all variants of Grub-Target-Option, namingly GPT-pMBR,
  BIOS_GRUB, /efi/boot (ESP), separate /boot (ext-|-2|-3|-4).

  Standard and OEM-Install.

  Haven't looked into Ubiquity-Source, but would assume, that between
  previous (<bionic) and latest (>bionic) something has changed as only
  bionic fails to replace BOOTX64 (as set before through Windows 10); If
  BOOTX64 is deleted before install via ubiquity the installer works
  correctly, identical to cosmic.

  Hope it helps.
