Abstract
A data processing system and method are described for booting a computer system from a virtual floppy diskette. A native operating system is executed by the computer system which utilizes a native file system. A boot able floppy diskette image is stored on the hard drive. The image includes a second operating system which utilizes a second file system. A master boot record stored on the hard drive is modified to include a boot bit. The boot bit is set in response to a storage of the image. The computer system is then booted from the image in response to the boot bit being set. The native operating system and the native file system are unchanged during the booting of the computer system from the image.
