Recovery disc

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. ==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. Hewlett-Packard, using the term System Recovery, describes it as destructive recovery. They even advise removing "extra hard drives" to prevent loss of this too. Although non-destructive alternatives do exist, the standard OEM Systems Recovery of Microsoft Windows-based operating systems involves booting from a separate hard drive partition, CD-ROM, or DVD, reformatting the hard drive and then copying operating system and software files. After the recovery process is completed, configuration such as the Windows Out-Of-Box Experience wizard is first run (along with any other additional setup the computer may perform), as it was on the initial startup of the computer. Most recovery systems use specialized software, though Toshiba and Dell licensed Norton Ghost technology for their recovery systems at one point.{{cite web |url=http://www.goodells.net/dellrestore/image.htm ==Details==

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. There's less cost to the OEM, but exposes the user to hard drive failure. An application used to create recovery discs or flash drive is sometimes offered to allow a backup of the recovery data.{{cite web |url=http://support.toshiba.ca/support/techsupport/tsbs/all/-TSB001019.htm 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. ==Disk image recovery==

The advantages of OEM recovery media can be had, without some of their disadvantages, by using disk imaging software such as Mondo Rescue or Acronis True Image to create a bootable recovery CD containing an image of the machine in the desired initial state. For example, a user can install their operating system, install all device drivers for their hardware, install other desired software, and configure other personal settings. Some smaller OEMs even use bootable CDs generated by this software as the actual recovery CD or DVD itself. ==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. == See also ==
