Next, create a boot menu inside the tftp root.

The :: symbol above allows us to reference the tftp root in an absolute way.
Ensure the current working directory is /mnt/data/netboot and run ln -rs pxelinux.cfg bios && ln -rs pxelinux.cfg efi64. This will link the menu configs for both bios and efi64 together.
From LinuxConfig.org article in Helpful Links Section: Here we used the -r option of the ln command to create relative symbolic links.
