@nsherin I didn’t use any other files beside the ones came with 18.04.1 LTS. Can you re-extract all files in 18.04.1LTS iso and then reupload them back to /images/os/ubuntu/18.04/mate. You might need to add this line to your /etc/exports file and restart nfs services or restart your fog server.

/images/os/ubuntu/18.04/mate *(ro,sync,no_wdelay,insecure_locks,no_root_squash,insecure)

Internet connection is still an issue with this method. You need to go to /etc/network/interfaces and change from manual to dhcp then restart your interface sudo /etc/init.d/networking restart

You need to add initrd=initrd.lz. I found it here: https://forums.fogproject.org/topic/11063/ubuntu-17-10-desktop-pxe-boot-no-internetl and it worked for me.

Your code should look something like this.

kernel nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/vmlinuz
initrd nfs://192.168.0.14/images/os/ubuntu/18.04/mate/casper/initrd.lz 
imgargs vmlinuz initrd=initrd.lz root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.0.14:/images/os/ubuntu/18.04/mate/ locale=en_GB.UTF-8 keyboard-configuration/layoutcode=gb quiet splash toram ip=dhcp rw
boot || goto MENU

@Sebastian-Roth @Tom-Elliott Huge thanks for the fix. 1709 is uploading after updating init and init_32.

@Sebastian-Roth Thanks a million. You’ve nailed it. I’ve tested it and it is the case with Sierra.

@CoolbluHat as Sebastian Roth said, you need to bless your clients (SIP must be disabled) or you can create a bootable usb

1. Format USB as FAT32
2. create folders in USB drive EFI\BOOT
3. Copy ipxe.efi in your tftpboot directory in your FOG server to EFI\boot and rename this file to bootx64.efi (try different *.efi files if this one does not work)

Prepare to upload image:
Like you do for Windows machines, create a standard image, add a new host for this Mac
create a new image in Image Management. Select Apple Mac OS, Multiple Partition Image - Single Disk
Schedule an image capture
Boot up this Mac using USB (hold down alt and select EFI).

You might need to grow the disk if you download the image to a bigger drive.

This method does not work for all Macs at least does not work on my MacBook Air early 2014 but worked on MacBook Air late 2015 using thunderbolt to ethernet with ssd formatted in 4K cluster size and most of the models with a built-in Ethernet card.

I saw that Debian released a stable version of DNSMASQ 2.76-5 for Stretch. Has anyone tried this version on Jessie? I want to use UEFI but worry about its comparability on Jessie. In general, is it okay to use packages designed for Stretch on Jessie?

@Tom-Elliott Does he needs to add /storage1 to /etc/exports?

I’m on 1.3.4 and have this exact same problem with Windows 10. You need to add 1 to a file in /images/YourWindows10ImageName/d1.fixed_size_partitions. I haven’t upgraded to R12 to see it addressed this issue. R10 did not addressed it so I reverted back to 1.3.4.

Thanks @Tom-Elliott I saw the folder. Sorry for being lazy. I’ll try it out and report back.

@Tom-Elliott Where can I get it?
They are old systems. Some as old as 5 yrs others about 3 years.
