Claim Text:
1. A computer-implemented method for restoring a system volume on a computing system from a network restore volume, the method comprising: receiving an indication to restore the system volume from the network restore volume; launching a network boot loader configured to perform disk I/O on the computing system, wherein the network boot loader is configured to load an operating system by performing read operations by reading from the network restore volume, wherein the network boot loader is configured to mount the system volume and redirect an interrupt associated with disk I/O to a redirector function configured to perform the read operations directed to the system volume by reading from the network restore volume and to perform the write operations by writing to the system volume; and after the network boot loader turns over control for disk I/O to the loaded operating system, launching a volume filter driver configured to perform read operations directed to the system volume from the network restore volume and to perform write operations by writing to the system volume.
