        @xutianhong what does the grub.conf look like?

          @xutianhong I say this because it appears from your directory tree there is no grub.cfg file.

              @xutianhong and what does your grub line look like?

              I would imagine it needs to look at the config file directly.

              I don’t know if it can be done in dnsmasq but possibly:
              pxe-service=BC_EFI,"BC_EFI","grub/grub-x86_64.efi --config-file=grub/efidefault",192.168.136.226

                @xutianhong I have to ask are you using FOG or are you using FOG for pxe only, or are you not using fog and have a question about pxe booting?

                I would ask why you do it this way? I would not use grub but the iPXE menu instead.

                    @xutianhong OK understand, I was confused because I think you use FOG and doing this.

                    You can still do what you want if you look at it a bit differently. FOG uses a pxe boot loader called iPXE. That is similar to syslinux and grub. But iPXE is very feature rich.

                    You can do what you are looking for if you know how to program your config menus.

                    Here is my dnsmasq config file

                    # Don't function as a DNS server:
port=0

# Log lots of extra information about DHCP transactions.
log-dhcp

# Set the root directory for files available via FTP.
tftp-root=/tftpboot

# The boot filename, Server name, Server Ip Address
dhcp-boot=undionly.kpxe,,<fog_server_IP>

# Disable re-use of the DHCP servername and filename fields as extra
# option space. That's to avoid confusing some old or broken DHCP clients.
dhcp-no-override

# inspect the vendor class string and match the text to set the tag
dhcp-vendorclass=BIOS,PXEClient:Arch:00000
dhcp-vendorclass=UEFI32,PXEClient:Arch:00006
dhcp-vendorclass=UEFI,PXEClient:Arch:00007
dhcp-vendorclass=UEFI64,PXEClient:Arch:00009

# Set the boot file name based on the matching tag from the vendor class (above)
dhcp-boot=net:UEFI32,i386-efi/ipxe.efi,,<fog_server_IP>
dhcp-boot=net:UEFI,ipxe.efi,,<fog_server_IP>
dhcp-boot=net:UEFI64,ipxe.efi,,<fog_server_IP>

# PXE menu.  The first part is the text displayed to the user.  The second is the timeout, in seconds.
pxe-prompt="Booting FOG Client", 1

# The known types are x86PC, PC98, IA64_EFI, Alpha, Arc_x86,
# Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI and X86-64_EFI
# This option is first and will be the default if there is no input from the user.
pxe-service=X86PC, "Boot to FOG", undionly.kpxe
pxe-service=X86-64_EFI, "Boot to FOG UEFI", ipxe.efi
pxe-service=BC_EFI, "Boot to FOG UEFI PXE-BC", ipxe.efi

dhcp-range=<fog_server_ip>,proxy

                    You replace the <fog_server_ip> with your address of your tftp server.

                      @xutianhong So are you using FOG and Cobbler together, or only came upon the post from a google search about a dnsmasq question? (I’m still willing to try to help, but this should be clear.)

                      I don’t know you’re native language so I can’t really provide a translation to try to make this a little easier for you.

                          @Tom-Elliott @george1421 thank you, im came up upon the post from a google search about dnsmasq&pxe boot question.
                          this is not wok. screen show uefi setting menu. not grub> yet.

                          pxe-service=BC_EFI,"BC_EFI",grub/grub-x86_64.efi --config-file=grub/efidefault,192.168.136.226

                          this website advice used in my first post. but static network setting not useful.

                          thank you @george1421 i tried ipxe, found it’s very powerful. i was working on it to try combine with cobbler.
                          but it’s looks like redhat 7.3 have a kernel bug for ipxe uefi boot. http://forum.ipxe.org/showthread.php?tid=8243&pid=13314#pid13314
                          finally solved.

                          i come from China.:bow_tone2: u know chinese? 😉

                            @xutianhong I don’t know Chinese, but google has an awesome translate feature. It’s not perfect I understand, but should be clear enough to give an understanding of what we are trying to say.

                            我不懂中文，但google有一个很棒的翻译功能。 这是不完美的我明白，但应该清楚，以了解我们正在试图说的话

                            Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

                                @xutianhong I’m glad you have it working. Tom and I are very skilled with FOG. Since fog is built using many other linux parts we know those parts too. iPXE is a great tool if you want to use it.

                                FOG also has a great pxe boot menu tool built in. I know some people install FOG just for pxe booting and don’t use FOG for computer imaging purposes.

                                You may ask a question here, we will help if possible.

                                Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!
