Product SiteDocumentation Site Configuring for EFI

  1. If tftp-server is not yet installed, run yum install tftp-server.
  2. In the tftp-server config file at /etc/xinet.d/tftp, change the disabled parameter from yes to no.
  3. Create a directory path within tftpboot for the EFI boot images, and then copy them from your boot directory:
    mkdir /var/lib/tftpboot/pxelinux
    mkdir /var/lib/tftpboot/pxelinux/bootx64.efi
    cp /boot/efi/EFI/redhat/grub.efi /var/lib/tftpboot/pxelinux/bootx64.efi
  4. Configure your DHCP server to use the EFI boot images packaged with GRUB. (If you do not have a DHCP server installed, refer to the DHCP Servers chapter in the Fedora Deployment Guide.)
    A sample configuration in /etc/dhcp/dhcpd.conf might look like:
      option space PXE;
      option PXE.mtftp-ip    code 1 = ip-address;
      option PXE.mtftp-cport code 2 = unsigned integer 16;
      option PXE.mtftp-sport code 3 = unsigned integer 16;
      option PXE.mtftp-tmout code 4 = unsigned integer 8;
      option PXE.mtftp-delay code 5 = unsigned integer 8;
      option arch code 93 = unsigned integer 16; # RFC4578
      subnet netmask {
              option routers;
              class "pxeclients" {
                      match if substring (option vendor-class-identifier, 0, 9) = "PXEClient";
                      if option arch = 00:06 {
                              filename "pxelinux/bootia32.efi";
                      } else if option arch = 00:07 {
                              filename "pxelinux/bootx64.efi";
                      } else {
                              filename "pxelinux/pxelinux.0";
              host example-ia32 {
                      hardware ethernet XX:YY:ZZ:11:22:33;
  5. Create a pxelinux.cfg directory within pxelinux:
    mkdir /var/lib/tftpboot/pxelinux/pxelinux.cfg
  6. Add a config file to this directory. The file should either be named efidefault or named after the IP address. For example, if your machine's IP address is, the filename would be 0A000001.
    A sample config file at /var/lib/tftpboot/pxelinux/pxelinux.cfg/efidefault might look like:
    title RHEL
            root (nd)
            kernel /rawhide-x86_64/vmlinuz
            initrd /rawhide-x86_64/initrd.img
    For instructions on how to specify the installation source, refer to Chapter 8, Configuring Installation Source
  7. Copy the splash image into your tftp root directory:
    cp /boot/grub/splash.xpm.gz /var/lib/tftpboot/pxelinux/splash.xpm.gz
  8. Copy the boot images into your tftp root directory:
     cp /path/to/x86_64/os/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/pxelinux/rawhide-x86_64/
  9. Reboot the system, and select the network device as your boot device when prompted.
