Recovery disc
The terms Recovery disc (or Disk), Rescue Disk/Disc and Emergency Disk
The focus of recovery or rescue is not to lose the data files on the hard drive; the focus of restore is to restore the operating system's functionality (and subsequently restore the contents of one's latest backups).[3]
The rescue/recovery tool uses media containing a
Overview
As an alternative to using media supplied with a system, it is possible to make one's own rescue/recovery disk. The Macintosh computer tool's name is Disk First Aid; on Windows systems there is a Create Disk function.[5]
Factory reset "recovery"
When a factory reset is done, user data is lost. The term "OEM recovery" refers to that type of "recovery." What is "recovered" is the original system. [6] Hewlett-Packard, using the term System Recovery, describes it as destructive[7] recovery. [8] They even advise removing "extra hard drives" to prevent loss of this too.
Although non-destructive alternatives do exist,

Recovery partitions
Most modern PCs store their recovery (non-destructive) or restore (destructive) tool on a hard drive partition rather than on bundled CD-ROMs or DVDs. They're typically accessed by using a specific key combination during system startup.[11] There's less cost to the OEM, but exposes the user to hard drive failure.
An application used to create recovery discs or
Some third-party software has the function to create a factory recovery partition and one key system backup and restore for Windows PC and Server.

Criticism
Many manufacturers do not supply a physical "recovery disc," but instead store the "recovery" (destructive) software tool on a partition of the hard disk. Some software that was preloaded may not be included; likewise some device drivers.
Alternatives
Prior to the use of recovery discs, one would use a boot disk to boot the system, then reinstall software as necessary from the original installation media.
A contemporary alternative, particularly used in Linux, is the installation disc or discs for a Linux distribution, or a Live CD or Live DVD – a bootable disc. These can be used to boot the system and then either manually troubleshoot and repair problems (in the case of a live disc), or re-install or re-configure the operating system. In the case of free software, operating systems can legally be re-packaged and distributed, and thus there is no barrier to making the full installation available. However, in the absence of a backup of system-specific configuration, which is provided on recovery discs, a re-installed operating system may require re-configuration.
Windows 8 includes two built-in recovery options, Refresh and Reset; Refresh re-installs Windows while preserving most user settings, while Reset performs a full restore back to its default configuration, similar to a factory restore function.[14][15]
