Ubuntu – How to avoid UEFI? Installation without UEFI? How to have Ubuntu 19 w/o UEFI

bootuefi

I need to install Ubuntu 19 on a quite recent machine.
I enabled all compatibility and legacy modes in BIOS to avoid UEFI.

I do not want to use UEFI.

The installation media (Ubuntu – ISO put on a USB-stick using dd) wants to force UEFI boot mode.
I want simple mbr and grub boot (although Lilo was so much better than grub). I totally decline to use UEFI.

How can I install Ubuntu without UEFI?

Force non- UEFI installation

a completely different way to avoid UEFI when installing Ubuntu

works for Ubuntu 18.04 (subsequent upgrade to 20.04 without issues):

Install via MinimalCD !

Quote from the Ubuntu Official Documentation:

The minimal iso image isn't useful for installing on UEFI-based systems that you want to run in UEFI mode. The mini iso lacks the proper files for booting the computer in UEFI mode. Thus, the computer will boot in BIOS compatibility mode, and the installation will be in BIOS mode.

  • the installation will be in BIOS mode

  • this has proven to work.

  • you can choose your Display (XFCE4, Unity, Gnome, ...) during
    installation

  • choosing server flavour during installation is provided by tasksel

  • no UEFI :-) Ubuntu without UEFI
