[Bug 1922528] Re: during install, grub failed

[pac1]

*Ubuntu
 Ubuntu (Safe Graphics)
 OEM install (for manufacturers)
 Test Memory

This menu shows on booting from memory sticks. Previously this just
booted directly into the display to run or install Ubuntu.

At the end of the install, a message appears that grub-install failed
and that the installation is stopped.  The installed system is unusable
even if you boot into another partition and run grub-install and update
grub from there.

Bug description:
  Not sure what's going on.  The installers for 2020.10 and 2021.04 seem
  to come up with a menu I've not seen before.  It includes a line for
  manufacturers.  I'll update the bug with more details later.
