Are you booting off a USB pen? I've sometimes had machines that blue screen when I use the USB pen i've created with BartPE+EETech. In thoses cases I've used a actual CD.
Also, had issues with AHCI drivers and the sata operations in BIOS that can sometimes cause blue screens. Usually i set it to ata and use the bartpe without ahci drivers. (also have another disk that has specific ahci drivers for specific laptops and i don't change the sata ops. Not sure why I've had to do this- but they seem to work!) (ps- remember to change bios back to original setting once finished)
