Split large install.wim image for GPT (fat32)

I would like to integrate updates and drivers to my windows 8.1 x64 image and install it as GPT/UEFI.

Latter requires fat32, which has trouble accepting the install.wim, grown over 4GB in the integration process. I've read on a few sites that splitting it using the /split image doesn't work for windows 8(.1).

Has anyone tried it recently? Is there any way to install a 4+GB image on GPT?

The latest verion of Rufus creates a small FAT32 partition to store an NTFS driver - and installs from a NTFS partition on UEFI systems.

I haven't tried it myself, but got it from the developer. Maybe worth a try.

wow, sounds interesting! I found the description, I hope it works well... Anyway, this driver is not retained in the final system - I guess/hope once the installation succeeds, it will be as good as any "official" way.

Yup... very cool - this is what it looks like in BootIce.
