The BMR restore process begins by booting the client (using the network boot) from a BMR boot server or from BMR prepared boot media (CD, DVD, or floppy).
If you use a network boot to begin the restore, boot media is not required.
If you have minimal network connectivity when you restore a client, Symantec recommends that you use the boot media that contains a shared resource tree.
More information is available about boot media and procedures for creating boot media.
