Overview of Restoring Windows with network boot.
- In a network boot, the BMR client boots from the shared resource tree on the BMR boot server.
- Windows systems network boot uses the PXE protocol. The BMR boot server provides and manages the PXE network services, but a DHCP service is required in the environment.
- The NIC on the client needs to be PXE compatible and enabled within the BIOS. It also needs to be the first boot device.
- BMR require a Boot Server in the same subnet of the client in order to do network boot.
- There needs to be an existing DHCP server within the network environment. Or else you may temporarily install and configure DHCP on the BMR Boot server and define a scope of IP addresses. This is purely Microsoft procedure and the external link below explains the procedures …
- BMR has its own PXE and TFTP service setup on BMR Boot server.
- PXE booting process involves two steps, client first broadcast DHCP request to get IP from DHCP SERVER that is available in that subnet and then uses TFTP to download boot image and additional files (i.e. BMR SRT in BMR NW boot case).
- The client first gets an IP from the DHCP server so that it can contact BMR master serverafter booting into BMR WinPE based restore environment. Once BMR master replies with the client configuration details, the correct intended IP will be set again by the BMR restore process.

How to network boot a Windows client?
- “Prepare to Restore” the client. For procedures, see "Preparing to restore a client" on page 54 of the Symantec NetBackup BMR Administrator's Guide
- PXE boot the client according to the hardware vendor instructions. On some systems, the BIOS displays a message that indicates that you can press a key to force a PXE boot. On others, you may have to modify the settings in the BIOS to add the network card to the default boot order.
- The following message should appear: "DHCP....Press F12 for network service boot”
- Press the Function 12 key and the system will boot and the restore begins with no further user intervention required
