I am afflicted with the well known >3GB RAM Vista issue that KB929777 addresses. As it turns out, I also got that exact same error while booting my newly created WinPE 2.0 usb flash drive. This is my first time using WinPE, but I immediately recognized that it was the same error I receive trying to install Vista with all my RAM installed. So I pulled out all but 2GB and tried again... WinPE booted no problem! So, my question is, is there any way to patch a WinPE 2.0 image to apply whatever fix KB929777 addresses?
