Boot code

Updated: 10/02/2017 by Computer Hope

Boot code is basically a set of "instructions" that are run by a computer when it is starting up. The boot code helps the computer prepare the system for loading and running an operating system, but boot code itself is usually not operating system specific. Boot code can be run from a hard drive or even directly from a computer CPU (if integrated into the silicon). Without boot code, a computer would likely not boot up correctly, if at all.
