Hi Win8 CAN install from split WIMs from FAT32 under UEFI (or MBR mode). If you try however, you will receive a 'microsoft licensing' error message. The problem is that Win8 does not use a \sources\ei.cfg file (unlike Win7). If you add a \sources\ei.cfg file which bypasses the prompt to ask for the Product Key and specifies VL or Retail, then you can install from .swm files. As this is my first post in this forum, I won't give more details or links, but this has been tested and proven independently and works.
