Multiple PE Versions per ISO

When I load an Windows ISO, I see multiple version including a PE version. When I add drivers, do I need to add them to all version including the PE?

Also, when I try to create an ISO after the update I can only select a single version. Will the PE version still be included? Does that mean that I lose the ability to select version during the install?

Thanks!
 
1. There are two nearly identical boot.wim images provided on every ISO: WinPE, and WinPE (Setup).

Obviously the key difference is the Setup edition does have the Windows Setup files. So when you're adding new drivers or the HW bypass settings, select the WinPE (Setup) image. The plain WinPE image is provided for reference to IT Pro's who are building their own install platform.

The bootloader knows to use WinPE (Setup), because of the marked boot flags. There's no need to remove the unused edition, since you're really not saving that much disk space on the ISO.

2. If you don't see all Windows editions listed by Setup, most likely you have an OEM product key in your BIOS. Setup will default to auto-selecting the same Windows edition as the OEM license (ie. Home for Home, Pro for Pro).

To allow all editions to be selected, create a new text file in the ISO's folder, "\sources\EI.cfg".

Thanks! Appreciate it! Loading the drivers to all the editions made bloated my ISO to 20GB!
 
One thing to be careful, if you load NVIDIA drivers then try to add a specific driver (INF) instance. Adding the entire folder will cause unnecessary duplication because each individual INF will make a separate copy of the NVIDIA driver DLL's. Which bloats the Windows drivers folder.

When you have a stable ISO that works, have NTLite compress the install WIM as ESD format. This is a very time consuming operation, so it should only be done when there's no other problems to fix.
 
Otherwise, instead of just integrating the .inf for the Nvidia driver (if you are not sure which one it is)
Add the Nvidia directory, which gives this

Then click on the "Exclude unused" button, and only the necessary driver is kept
