How do OS installers works if there isn’t any OS that could manage applications in an empty computer?
In: Technology
You insert a boot medium (optical disk, USB drive, SD card, whatever) and tell the computer to load that OS during its UEFI/BIOS startup. It is loaded into memory and runs the computer from there. You then use that to install the permanent OS on the computer’s durable storage so you don’t need the boot medium every time.
