How do OS installers works if there isn’t any OS that could manage applications in an empty computer?
In: Technology
To explain it a different way, the installer itself acts as a temporary OS. The BIOS activates it and then it’s able to build a more permanent one.
Kinda like when they put up a construction crane, they build it as a small version, then use it to build itself up to full height.
You need that temporary small OS with no features other than the ones needs to install a bigger OS to make said larger OS happen.
