Abstract:
1. A method comprising: receiving, by a network device, a bootable image file of a first operating system that is different from a second operating system being run by the network device, allocating, by the network device, contiguous space on a drive of the network device, copying, by the network device, the bootable image file to the contiguous space on the drive of the network device; modifying, by the network device, a master boot record of the drive of the network device to indicate, in the master boot record, that the contiguous space on the drive of the network device is a bootable partition of the drive of the network device; placing, by the network device, hardware of the network device into a pass-through mode that allows traffic to pass through the network device without direction from the second operating system; and causing, by the network device, the network device to reboot to load the first operating system.
