A
hard reboot (also known as a
cold reboot,
cold boot or
cold start) is when power to a computer is cycled (turned off and then on) or a special reset signal to the
processor is triggered (from a front panel switch of some sort). This restarts the computer without first performing any shut-down procedure. (With many
operating systems, especially those using
disk caches, after a hard reboot the filesystem may be in an "unclean" state, and an automatic scan of on-disk filesystem structures will be done before normal operation can begin.) It may be caused by power failure, be done by accident, or be done deliberately as a last resort to forcibly retrieve the system from instances such as a critical error or
virus-inflicted
DoS attack.
