A cold boot occurs when the power supply is interrupted for any reason. A warm boot does not interrupt the power supply, which may result in parts of the hardware being left in an uninitialised state. When diagnosing hardware issues, a cold boot is recommended to ensure the boot is consistent. It is also best to allow at least 1 minute of inactivity to allow any residual currents to fully dissipate before restoring the power supply.

A cold boot is initiated by shutting down the system from within the OS, or by holding and then releasing the reset button, or by switching the power off at source.

A warm boot is initiated by restarting the system from within the OS.

Hibernation is akin to a cold boot as power must be interrupted. However, the machine's hardware is initialised from the memory dump created during hibernation, thus restoring the system to the exact state it was in prior to hibernation (and thus speeding up the entire boot process).

Suspension or sleep is neither a hot nor cold boot as only certain parts of the hardware are switched on and off to conserve energy. Although hardware returning from the sleep state needs to reinitialised to their previous state, the contents of memory remain active at all times, thus it is not considered a boot of any kind.

A cold boot is when a computer initializes without having run for a while, hence, it's 'cold'. For example, when you turn on your computer in the morning when it has not been on since the previous day. A warm boot is when a computer restarts after running, while it's 'warm'.

Explain how cold boot different from a warm boot?

Warm boot: not all the processes shut down. It does not take as long for a warm boot and many times users do not have to be off the system. Cold boot: Everything shuts down. There are shutdown scripts which shut down all the processes (so nothing is missed). All users must be off the system. Then, you run the startup script (check for errors). Test the system to make sure the changes you made took effect and there's no problems. Warm boot example: Configurable parameter was changed and the documentation states in order for it to take effect, a warm boot is required. In the documentation for that particular system, a warm boot's criteria will be listed. Cold boot example: Operating system upgrade on the server.

What type of boot occurs when the computer is already on and you restart it without turning off the computer?

The different between cold and warm start?

Cold boot, also called a hard boot, is starting your computer from a completely shut down state. You turn the machine on when it has no electricity running. Warm boot, or a soft boot, is nothing more that using the restart function - you don't shut the power off, you use the software to restart so the operating system.


What is cold booting and warm booting in detail?

A warm boot, accomplished by pressing the CTRL+ALT+DEL key combination, restarts the computer through the INT19h ROM BIOS routine. This warm-boot procedure usually does not go through the complete boot process; generally, it skips the power-on self test (POST) to save time. In addition, a warm boot frequently fails to reset all adapters in the computer's adapter slots. If you use the Reset button to cold boot the computer, it generally restarts the boot process, including the POST. However, this procedure does not necessarily discontinue power to the motherboard. If the power is not interrupted, the cold boot may fail to reset all adapters in the computer's adapter slots.
