Booting - Wikipedia, the free encyclopedia |
 | | Typical modern PCs boot in about a minute (of which about 15 seconds are taken by the preliminary boot loaders, and the rest by loading the operating system), while large servers may take several minutes to boot and to start all services - to ensure high availability, they bring up some services before others. |
 | | If there is no active partition or the active partition's boot sector is invalid, the MBR may load a secondary boot loader and pass control to it and this secondary boot loader will select a partition (often via user input) and load its boot sector, which usually loads the corresponding operating system Kernel. |
 | | Warm boot or soft reboot (as opposed to hard reboot) refers to an abridged start up which does not require that power be removed and reapplied. |
