Description: A bootable DVD is an optical disc that contains an image of an operating system that can be used to start a computer. This type of DVD is essential in the realm of virtualization and operating system installation, as it allows users to load an operating environment directly from the disc. The operating system image, which can be Windows, Linux, or other operating systems, is burned onto the DVD in such a way that the computer can recognize it as a boot medium. When booting the system from the DVD, the user can access installation tools, recovery options, or even run operating systems in ‘live’ mode, allowing them to test the system without needing to install it on the hard drive. Bootable DVDs are particularly useful in situations where the existing operating system is damaged or when a clean installation is desired. Additionally, they are a valuable tool for developers and system administrators who need to test different configurations or operating systems without compromising the main computer environment.
