@Tom-S said in Cannot Boot Macbook 7,1 from PXE:
LOL, Apple and its proprietary way of doing things. Simple explanation, netboot is not pxe boot. OS X is very picky about netboot. The efi iPxe file first must be named boot.efi as well as match the architecture of the machine that is booting (for you thats 64 bit) secondly not all ethernet or wifi adapters will be visible to iPxe after handoff. DHCP must point to that file as well as the boot file also.
I have lots of experience with imaging Macs with FOG. We do about 1500 or more a year.
Basically you have a few options but I will line out what we do. When I create an image, on the “master” machine I create the smallest partition possible. In that partition I add the folders:
/System/Library/CoreServices/After that I add the 64 or 32 bit ipxe file naming it boot.efi. Again for you thats a 64 bit file
Now on reboot, hold down option and select that partition. If it is able to find your nics and boot to FOG then you are in good shape!!. If it works copy the partition you just created to a usb disk. Now use that to boot your machines. Realize that you can simply select the usb disk in the boot manager and once iPxe loads up pull it out, and use it on another machine (if you are doing multiple machines). Because of limitations in iPxe do not expect a pretty FOG Menu. No background picture and such.
If your nics are not visible to the efi iPXE then you will need to use the undionly.kpxe file. That is a lot more tricky!! But if needed I will explain to you!
I hope this helps a little
