==Microsoft definition==

Since [[Windows NT 3.1]] (the first version of Windows NT),<ref>{{cite web|url=https://support.microsoft.com/en-us/kb/100525|title=Definition of System and Boot Partition|last=|first=|date=20 February 2007|website=Support|publisher=[[Microsoft]]|archive-url=https://web.archive.org/web/20160313090403/https://support.microsoft.com/en-us/kb/100525|archive-date=13 March 2016|dead-url=yes|accessdate=}}</ref> Microsoft has defined the terms as follows:

*The ''boot partition'' (or boot volume)<ref name=":1" /> is the disk partition that contains the operating system folder, known as the ''system root'' or <code>%systemroot%</code> in [[Windows NT]].<ref name=":0" />{{Rp|174}}

A single partition may be both a system and a boot partition. Ironically, however, in case they are separate, the boot partition does not contain the boot loader and the system partition does not have the system root.<ref name=winternals5 />{{rp|971}}
