Abstract:
A method for specifying an operating system (OS) file to use in a computing system after a system reboot begins by copying at least one new OS file to a system disk. An OS file to be installed is selected from the new OS files on the disk. The system is booted into the selected OS file, the selected OS file becoming the currently running OS on the system. A boot pointer on the system disk is updated to point to the selected OS file, such that any subsequent reboot will be into the selected OS file.
