when the computer is turned on for the first time, how does the operating system gets loaded from the hard disk to the ram? cause the o/s permits the programs to get booted but if the o/s is also in the hard disk, who permits it to be booted?
In: Technology
The BIOS/UEFI’s bootloader.
It’s very basic, just as in the name, but it’s enough to start a more complex bootloader such as GRUB or the Windows BL.
The whole thing is wired to work this way, the processor first starts that primary basic bootloader, then it’s all just code. All the way from Assembly to Python.
