Korjauslevynä

Korjauslevynä, meaning "as a repair disc" in Finnish, refers to the concept of using a storage medium, typically a CD or DVD, to boot a computer and perform diagnostic or repair operations. In the past, when operating systems were primarily installed from optical media, a spare installation disc often served this dual purpose. These discs would contain a recovery environment or specialized tools that could be accessed without needing to boot into the installed operating system.

The functionality of a korjauslevynä could range from simple file system checks and repairs to more advanced tasks like registry editing, system file restoration, or even complete operating system reinstallation. The specific tools available would depend on the operating system and the edition of the disc. For example, Windows installation discs often included a "Repair your computer" option that launched a command prompt or a troubleshooting wizard.

With the widespread adoption of USB drives for operating system installations and the increasing complexity of modern operating system recovery options accessed through boot menus or cloud services, the traditional korjauslevynä using optical discs has become less common. However, the underlying principle of using a separate bootable medium for system repair remains relevant, now often implemented through bootable USB drives containing specialized diagnostic and recovery software. These modern equivalents serve the same purpose as the historical korjauslevynä, providing a means to address system issues when the primary operating system is inaccessible.
