Hello KehoeMD,
I am sorry you are having problems with this.
From our side you can use the F6 drivers for IRSTe so you can do the bundle with WinPE but I see you are already using it (iaStorF). This installation is not supported from our side so I would strongly recommend you to contact Microsoft for further assistance on this WinPE installation.
I will pass the information to development though. You can also refer to the following link for WinPE installation:
