I have been investigating MDT for a while now but am now thinking what I am wanting to do is not possible. I have done many google/bing searches and haven't been able to find anything or what I have found doesn't seem to work in my case.

So here is what we are needing -

1. We need two different boot options one for a regular server and another that gets the server ready to have something else ran on it.
2. The first install/task sequence installs Server 2016 and runs some simple applications and joins it to a domain.
3. The second install/task sequence installs Server 2012 R2 and does a lot more in-depth stuff such as connecting to remote services to install other things and get information databases to configure locally.

Right now the second install is all built into a custom WIM image we PXE boot into and runs through everything manually. I wrote this script and it works for the most part, however it can be very cumbersome to maintain. We also have the option to remotely force these machines to boot into this image to start everything from scratch again.

As of right now I am stuck as I am needing to have both sequences have 2 different boot-able options, we can boot into it and then select which task sequence we want, however how can I automate that task sequence selection remotely which gives us the opportunity to click a button on our website that tells the server to boot into the image and run through the entire process automatically with the one we selected.

I found you can select a customsettings.ini per task sequence but I still need to determine that outside of MDT, is there any way to do this? I have thought creating 2 different deployment shares but then I have to maintain the applications. How can you create an end to end automated image using MDT? I can't see to figure this out. I may have terminology wrong in this and I probably sucked at explaining it lol.
