[Bug 1924823] Re: ESP on install medium automatically configured as ESP for install, failing install

[Chris Guiver]

Further to comment #9  (with the idea of work-around) I initial-booted
the thumb-drive (installation media) but by editing the grub entry (so
instead of booting it normally; it booted the installed (sda1) system
instead using `chainloader (hd1)+1`)

and my installed version booted.

I ejected the thumb-drive and tried to grub-install but get

guiverc at dc7700:~$ sudo grub-install /dev/sda
[sudo] password for guiverc: 
Installing for i386-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
grub-install: warning: Embedding is not possible.  GRUB can only be installed in this setup by using blocklists.  However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.

I'm fearful this won't boot... so no workaround..

Title:
  ESP on install medium automatically configured as ESP for install,
  failing install

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  This bug report is a duplicated of bug #1902269 performed with Ubuntu 20.10.
  Basically installation fail when the installer doesn't find an EFI (ESR) partition on computers with legacy BIOS.

  This time I have used Ubuntu 21.04 also to test the new version of
  Ubiquity package (21.04.15) which, as reported here:
  https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1893964/comments/22
  should have fixed the issue.

  Unfortunately I'm still experiencing the same problem.

  #### Partition details:
  - msdos partition table
  - 4 primary partitions, all ext4
