Cold Booting vs. Warm Booting: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on February 8, 2024
Cold booting refers to starting a computer from a completely powered-off state, while warm booting means restarting a computer that's already on.

Key Differences

Cold booting, also known as a hard boot, involves starting the computer from an off state, initiating a full reboot sequence. Warm booting, also known as a soft boot, restarts the computer without turning off the power, often using the operating system's restart command.

In cold booting, the computer performs a full diagnostic and initializes all hardware components from scratch. Warm booting skips certain initial checks, relying on the existing power state and memory contents for quicker startup.
