Reviving this thread!
Anyone else tried this procedure but for a ia64 architecture?
No problems till I get to the last step. It seems that the AIK doesn't put the etfsboot.com file in the Boot folder so it doesn't get copied into the winpe folder. I manually copied the file over.
Continued, created the image file, burned a disc but it won't boot with a can't find boot manager. I copied the etfsboot.com file into the ia64 folder, so it gets copied with the rest, deleted the winpe folder and tried again.
I got a ISO file that was slightly bigger but still get the same error! EDIT:
Whoops! Should have used amd64 instead of ia64. That worked for me but I expected a low graphic GUI but it's only a command line prompt.
