That's wrong! You have to replace "partition=c:" through "boot". After that BCDEdit commands will run fine. Thank's MS for some further wasted days!!! However USB-Stick is still not booting WinPE. But I guess that has something to do with combination of BIOS and Stick. Martin Can you elaborate on the exact commands you are running to create the new BCD file? I'm having a hard time translating: ... into the actual BCD commands. The verbiage in readme.rtf states: Thanks!
