    I have Acronis True Image 2017 ISO written onto my 64GB SanDisk 64GB flash drive. I used the GPT for UEFI partition and the tool to make the flash drive bootable was of course RUFUS.

    Now I want to create an AIO bootable flash drive that will include:
    1. Acronis True Image 2017 (UEFI GPT)
    2. Windows 10 Pro x64 MSMG Custom Edit (UEFI GPT)
    3. AIO System Rescue Toolkit (UEFI GPT)

    How can I make it happen? I just tried YUMI UEFI and its messed up, telling me my 64GB flash drive does not have enough space for WIM file of about 6GB and I assure you it does.

    Which tool do you suggest I try??? I wish good old RUFUS would have this feature...

    Rufus create a small hidden partition in fat32 for uefi boot, the big partition is format in NTFS and have no limit of 4GB.
    Yumi and other, format the entire usb key in FAT32 which as 4GB limit for single file.

    If you use rufus, in necessary modify (with bcdedit command or Easybcd) the hidden file "bcd" stored in efi\microsoft\boot folder, adding the relative entry for any file wim.
