Abstract
The claimed subject matter provides a system or method for managing software changes. An exemplary method comprises creating a reset boot loader, a last known good (LKG) boot loader, and a current boot loader, then pointing the reset boot loader, LKG boot loader, and current boot loader to a parent virtual hard disk (VHD) containing a default master image. An operation to perform is determined, and a service partition is booted into. The LKG boot loader or current boot loader is pointed to a child VHD loaded with another desired image based on the operation selected, and the system is rebooted into the parent VHD or child VHD pointed to by the current boot loader.
