Image with High Sierra 10.13.6 without using APFS - Deploy as HFS+

I'm going to post this for everyone looking to deploy High Sierra 10.13.6 without using APFS as your file system. You can migrate to APFS after deploying your OS if you prefer.

1) Backend
    Mac Pro Late 2013 - SAN attached storage
    DS 1.7.8
    Server OS High Sierra 10.13.6
    Netboot Set DS 10.13.6

2) You'll need to create a 10.12.6 Installer and a 10.13.6 Installer. Boot to your 10.12.6 installer but also plug in your 10.13.6 installer as well.

Credit to this blog with the initial find. I've changed the commands slightly.

You can now use the Disk Utility of the recovery OS you currently booted from to reformat your hard drive.

Format the volume HFS+ journaled and choose a simple name, such as internal

Attach the USB stick which contains the High Sierra installer.

Now exit Disk Utility and open a Terminal. Go or "cd" to the Volume of your attached High Sierra USB Stick:

cd /Volumes/Install\ macOS\ High\ Sierra/

Start the installation of High Sierra and point it to the freshly formatted HFS+ volume, named internal with command below.  (This installation will also create the Recovery HD partition for you)

"Install macOS High Sierra.app“/Contents/Resources/startosinstall –volume /Volumes/internal –converttoapfs NO

Agree to the License and let the High Sierra installer complete.

After the OS is complete you can login and check your filesystem in diskutility and you will have installed High Sierra on a HFS+ filesystem.

Now, you can netboot back into deploystudio and pull your High Sierra image as HFS+ and can deploy the image like any other workflow you have created.

******* GOTCHAS **********

The Recovery partition is 515MB in size. If you select "Pre-allocate space for Recovery partition" by default the 1GB partition is not big enough. The High Sierra recovery partition is larger than the previous 10.12.6 & 10.11.6 images. Deselect the "Pre-allocate space for Recovery partition" and create a second partition scheme to have a partition size as 2 GB. This worked for me.

Thank you, it worked!

I just did it differently, I started the DeployStudio boot (with the High Sierra OS plugged in) and I used the DeployStudio terminal.

Because the Imac does not accept below High Sierra.

Thanks! I know the article is a little rough but I appreciate it. Would like to be able to deploy with apfs but I haven't figured out a way yet.

I attempting to boot to the USB using 10.12.6, but after it runs for a bit, it brings up a popup  to choose startup disk or update.  If I choose update, it looks like it's updating, but comes back to the screen and when I choose startup desk it will eventually bring back the prompt
