How do OS installers works if there isn’t any OS that could manage applications in an empty computer?
In: Technology
Just to avoid confusion should you choose to research this a bit more:
The BIOS is no more. The technology had quite a number of restrictions. Intel developed something called the “Extensible Firmware Interface” (EFI) way back together with a now failed hardware plattform (Itanium).
It took a while until this became widely adopted (I think, Apple first used it on the – at the time – new Intel-based Macs). Nowadays, basically every modern PCs (and other platforms) come with the Universal EFI (UEFI) technology on board which, aside from starting up the whole computer, supports a lot more (e.g. to remotely manage computers in enterprise environments etc.)
But regarding your question: Today, on a modern computer, the UEFI does what the BIOS did – just not in such a very basic manner anymore.
Most computers still allow “legacy booting” with the old BIOS interface but that will disappear in time (and has disappeared for a lot of “made for business” PCs e.g. from Dell or HP)
