Abstract
An upgrade procedure may be executed at a network device to allow the network device to automatically upgrade an operating system to a new operating system. The upgrade procedure may include receiving a bootable image file of an upgrade operating system that is different from an operating system being run by the network device and which uses a file system format that is different from the file system format of the operating system being run by the network device. The bootable image file includes a binary file format that conforms to the file system format used by the upgrade operating system. The network device allocates contiguous space on a drive of the network device and copies the bootable image file to the contiguous space. The network device also modifies a master boot record of the drive such that the contiguous space on the drive is reflected in the master boot record as a bootable partition of the drive.
