      @KnightRaven Yeah, I see the issue right away. When you are back on this project create a new thread and we can work through what needs to be done. You are missing a few lines that make the uefi bit work.

      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!

        hi, when saw dnsmasq maillist http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2017q2/011379.html

        3q for https://github.com/openSUSE/kiwi/wiki/Setup-PXE-boot-with-EFI-using-grub2 & https://www.ibm.com/developerworks/community/blogs/a2674a1d-a968-4f17-998f-b8b38497c9f7/entry/uefi-grub2?lang=ru

        the problem may not in dnsmasq, when update to version 2.76. uefi boot can see grub>

        My env is all in VMware Workstation 12 Pro 12.0.0 build-2985596
        NAT mode
        192.168.136.200 to dhcp server centos7.3
        192.168.136.226 to cobbler( tftpserver & dnsmasq ) centos7.3
        dhcp to cobblerctos73(legacy bios)
        dhcp to uefi(efi)

        1. 136.200 install dhcpd
          conf file like blow
        dns-update-style interim;
        
        subnet 192.168.136.0 netmask 255.255.255.0 {
             option routers             192.168.136.2;
             option domain-name-servers 192.168.136.2;
             option subnet-mask         255.255.255.0;
             range dynamic-bootp        192.168.136.240 192.168.136.250;
             default-lease-time         21600;
             max-lease-time             43200;
        }
        
        1. 136.226 install centosbase dnsmasq then upgrade to 2.76 from souce, see
          https://wiki.fogproject.org/wiki/index.php?title=ProxyDHCP_with_dnsmasq#Compiling dnsmasq 2.76 if you need uefi support
        #define HAVE_DBUS
        #define HAVE_IDN
        /*#define HAVE_IDN_STATIC*/??? this line not need? cuz my centos73 not support this when do make
        #define HAVE_CONNTRACK
        #define HAVE_DNSSEC
        

        then dnsmasq conf file like blow

        # 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=/var/lib/tftpboot
        
        # 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=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:BIOS,pxelinux.0,,192.168.136.226
        #dhcp-boot=net:UEFI32,grub/grub-x86.efi,,192.168.136.226

        #dhcp-boot=net:UEFI64,grub/grub-x86_64.efi,,192.168.136.226
        
        # The boot filename, Server name, Server Ip Address
        dhcp-boot=pxelinux.0,,192.168.136.226
        
        # PXE menu.  The first part is the text displayed to the user.  The second is the timeout, in seconds.
        pxe-prompt="Booting UAT Autoinstall Client", 1
        
        dhcp-range=192.168.136.200,proxy
        
        
        #legacy bios options
        pxe-service=X86PC,"Legacy",pxelinux,192.168.136.226
        
        #vmware workstation 12 EFI options
        pxe-service=BC_EFI,"BC_EFI",bootx64.efi,192.168.136.226
        
        1. I find many other doc, all can’t work, till this two, see
          https://github.com/openSUSE/kiwi/wiki/Setup-PXE-boot-with-EFI-using-grub2
          https://www.ibm.com/developerworks/community/blogs/a2674a1d-a968-4f17-998f-b8b38497c9f7/entry/uefi-grub2?lang=ru

        it’s use pxe to boot diskless linux, when finish 1&2, I can see grub>. So ….

        Tftproot is /var/lib/tftpboot

        1. Mkdir tftproot/boot/grub(in cobbler it already have)

        2. Vim tftproot/boot/grub/grub.cfg blow this

        set timeout=5
        menuentry 'Linux diskless' --class os {
             insmod net
             insmod efinet
             insmod tftp
             insmod gzio
             insmod part_gpt
             insmod efi_gop
             insmod efi_uga
             # dhcp, tftp server in my network
             set net_default_server=192.168.136.226
             # auto dhcp setup did not work for me, no idea why
             # net_bootp
             # ok let's assign a static address for now
             net_add_addr eno0 efinet0 192.168.136.246
             echo 'Network status: '
             net_ls_cards
             net_ls_addr
             net_ls_routes
             echo 'Loading Linux ...'
             linux (tftp)/boot/vmlinuz inst.ks=http://192.168.136.226/cblr/svc/op/ks/profile/rhel73-x86_64
             echo 'Loading initial ramdisk ...'
             initrd (tftp)/boot/initrd.img
        }
        
        1. grub2-mkstandalone -d /usr/lib/grub/x86_64-efi/ -O x86_64-efi --fonts=“unicode” -o /var/lib/tftpboot/bootx64.efi boot/grub/grub.cfg
        2. systemctl restart dnsmasq.

        Just power up uefi.

        ***Now, the uefi boot is done.
        It’s not perfect.
        Cuz in grub.cfg we need write nextserver ip & host ip,
        And grub2-mkstandalone command write grub.cfg in bootx64.efi, cuz I change boot/grub/grub.cfg it’s. not working.
        So now I working to grub lib, want find way to solve this 3 problem.

        If anybody working with grub/grub2, can give me some idea? thank you very much.***

          @xutianhong of just use refind which is meant to automatically use EFI?

              @xutianhong I’m not sure I follow. Grub and rEFInd are exit types, to leave pxe and boot to HDD.

                If you’re simply trying to boot an iso, ipxe supports this natively.

                      @xutianhong Can you explain what your trouble is? I read your first post and it was not clear, I think maybe the language translation.

                      Your first post make me think you are telling us what you find not asking for help.

                        @george1421 ok. i was using cobbler install redhat @ my work env. at first i found all works fine @ legacy bios. but when shift to UEFI. its’ not work good anymore. cobbler+dnsmasq.proxymode, msg freeze at option 47. i search google and found fog.wiki have advice dnsmasq need upgrade to 2.76. i do it. at this time , screen show grub>. then i search @ dnsmasq mail list and other website. find some way to figure this write in my first post. but it’s need write static ip&nextserver info to cfg, make standalone efi file. then Tom Elliott suggest ipxe & rEFInd.

                            @xutianhong said in Dnsmasq bios and uefi:

                            need upgrade to 2.76. i do it. at this time , screen show grub>. then i search @ dnsmasq mail list and other website. find some way to figure this write in my first post.

                            What confuses me is you say dnsmasq and then grub. This is the confusion. dnsmasq is used to send the proper boot information to the target computer to get the target to load the FOG iPXE menu. Once the iPXE menu is displayed dnsmasq is no longer needed.

                            Once the iPXE menu is displayed you must make a menu pick within a few seconds or the iPXE menu picks boot from local hard drive to boot.

                            This is where the iPXE menu uses the (default) sanboot process for finding the hard drive on bios (legacy) computers. If your target computer is uefi then you can use grub, but most will use rEFInd to identify the boot partition on the hard drive. If rEFInd can’t find the boot partition you may need to adjust the refind.conf file to search more locations.

                            I want to be clear that if your target computer boots into the FOG iPXE menu then dnsmasq is working correctly.

                            If you are having a problem leaving the iPXE menu and booting from the local hard drive then this is an iPXE problem.

                                    @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.
