Windows based netboot server for ubuntu
PXE: Preboot Execution Enviornment
PXE is a client-server interface that allows computers in a network to be booted from the server before deploying the obtained PC image in local and remote offices, for PXE enabled clients. PXE network boot is performed using client-server protocols like DHCP(Dynamic Host Configuration Protocol) and TFTP(Trivial File Transfer Protocol). PXE will be enabled by default on all computers.
Before a PXE network boot, the DHCP server/scope Options 66 and 67 should be configure

Boot Ubuntu 20.04 LTS Over Network PXE Using SERVA on Windows 7/8/10
https://help.ubuntu.com/community/Installation/WindowsServerNetboot
DHCP options for PXE
- Enable 066 Boot Server Host Name and enter the string value as the IP address of the machine where Desktop Central server is installed. If you are deploying OS in remote office, enter string value as IP address of the machine where distribution server of that remote office is installed.
- Enable 067 Bootfile Name and enter the string value as boot\pxeboot.n12 to boot machines via legacy BIOS.
- Both the values, boot/pxeboot.n12and EFI/Boot/bootx64.efi are case sensitive.
- To boot the machines via UEFI mode, for 64-bit computers enter the string valuse as EFI\Boot\bootx64.efi and for 32-bit computers, enter the string value as EFI\Boot\bootia32.efi. Now click Apply and OK.
DHCP configuration process
- The client computer sends a 'discover' packet in the form of a broadcast requesting for network configuration. This packet will be received by the DHCP server.
- An 'offer' packet will be sent from a DHCP server to the client. After analyzing the 'offer', the client will be assigned the network parameters like IP address, subnet mask, etc.
PXE Boot Process
- The client will notify the DHCP, that it is using PXE boot server. The DHCP server will send the Next Boot Server's IP address(Option 66) and the Boot Filename(Option 67) to the client.
- The client will contact the PXE boot server and request for the boot files.
- The PXE boot server will send the boot files to the client through the Trivial File Transfer Protocol (TFTP).
- In the DHCP server, Options 66 and 67 can be configured under scope or server options. This aids in the loading and launching of the boot files for the client computer.
