as far as I can tell, you need a WinPE BootCD with EETech implemented. There are several good Tutorials for it but I recommend this one:
Please be advised it is not reasonable to create this without informing your IT-Stuff, nor do you get alle the Files you need to for building the BootCD. A simple Emergency Boot seems unreasonable due to the system32-error.
