Title:
  Ubiquity creates useless ESR (EFI) partition on Bios system

Status in ubiquity package in Ubuntu:
  Opinion

Bug description:
  Ubuntu 21.04 - 16/4 daily build - Ubiquity 21.04.15

  Even on computers with old BIOS an ESR (EFI) partition will be
  automatically created when installing Ubuntu using one of the
  automatic options like "Erase disk and install Ubuntu", "Install
  Ubuntu alongside other system", etc..

  This should not happens. No ESR partition should be created on systems
  with old BIOS.

  In this case:
  - 2 partition where already existing:
    - /dev/sda1 Ext4 with Ubuntu 21.04 already installed
    - /dev/sda2 Ext4 empty
  - Performed the "Install Ubuntu alongside other system" install option".
  - After install:
    - /dev/sda3 Fat32 ESP
    - /dev/sd4  extended
    - /dev/sda5 Ext4 with new Ubuntu 21.04

  I've set just 2 existing primary partition because if the installer
  doesn't find a primary partition for ESR, installation will fail....
  and that's another bug, see bug #1924823

  In this case installation will succeed, but just think about all the
  systems with old BIOS that are already using 3 primary partitions and
  there's no extra primary partition for ESR.. in that case installation
  fails.
