For anyone who actually would like to know how modern machine boots, in a way which is practical and not just theoretical, this article is probably the best there is.<p>Definitely recommended for someone coming from the legacy BIOS boot background, expecting UEFI to be the same. (Hint: It isn&#x27;t)<p>Basically while legacy booting has too many black boxes and black magic (from an end-user perspective) to be practical to work with, UEFI is actually inspectable and debuggable. If something fails, you can figure out why.<p>Best of all: Creating live USBs&#x2F;CDs&#x2F;whatever no longer requires special tools. Just copy the everything, including the EFI folder, and its automatically bootable.<p>UEFI is awesome.
