Ask HN: Where can I find a primer on how computers boot?
The following is a pretty decent historical page about the pre-(U)EFI MBR (Master Boot Record) boot process:
https://thestarman.pcministry.com/asm/mbr/STDMBR.htm
Note that EFI/UEFI -- occurred much later in time than MBR...
Related: https://en.wikipedia.org/wiki/Master_boot_record
You might also wish to check out some emulators, most notably Bochs (https://bochs.sourceforge.io/) and QEMU (https://www.qemu.org/) because they simulate the boot process, and if you're in their debuggers, you should be able to inspect that process step by step -- but also more generally emulators for other machines/platforms/architectures (https://en.wikipedia.org/wiki/List_of_computer_system_emulat...) -- because in general, most of those emulators should simulate the given machine/platform/architecture's boot process...

Can anyone recommend some good free tools for programming, debugging, and virtualization on Ubuntu?
With both of those you can make some really nice DOS programs. Which you can then run in bochs (not virtualized, but an emulator. Close enough :) ).
