A system for modifying a virtual disk to provide network interface card (NIC) teaming capabilities to a virtual disk. The system can include a virtual disk that has access to one or more NICs. In some instances, the NICs are included in a NIC team that is also available to the virtual disk. A teaming module executing on a computer can identify the NIC team and responsively obtain a media access control (MAC) address of the NIC team. In response to obtaining the NIC team MAC address, the teaming module can obtain a network boot MAC address that was used to PXE boot the virtual disk. The teaming module can then replace the NIC team MAC address of each NIC in the NIC team with the obtained network boot MAC address. The system then boots from the virtual disk that has the modified NIC team configuration.
