Netboot image making

[anickless]

So I am trying to create a new netboot image for some new iMac's updated to 10.11.6 and with macmule's autocaspernbi it errors on the "disable software updates" .

even with casper netinstall image creator it fails miserably

Any suggestions?

What version is your previous netboot set? If they were updated to 10.11.6, shouldn't they be able to boot from your previous nbi

@anickless It's the OS.dmg.

I'm guessing it's not a clean OS.dmg created with AutoDMG etc, but rather some artisianal one.

It'll work if you use a AutoDMG created OS.dmg.

Here is what I am seeing via composer, comparing the size that I make now vs my old one is a big difference. Not sure why one part of the drive is not selectable.

@CapU These new iMacs have higher specs than the netboot image and so will not netboot, I am trying to use one to make a new netboot to keep things current.

@anickless Can you create an OS.dmg using AutoDMG?
