    How to boot windows 8.1 using a NTFS USB drive?


    Hi all,
    This is my first post.

    I have a Chinese tablet Chuwi v10HD with EUFI Bios which supports GPT Fat32 usb drives to install Windows 8.1.
    Can anyone help me, how can I boot into a ntfs file system USB drive and continue my windows installation.

    NB: I want NTFS as my install.wim file is over 5 GB and FAT will not support more than 4GB file.

    Dism /Split-Image /ImageFile:X:\install.wim /SWMFile:X:\install.swm /FileSize:2500

    you would just need to split your install.wim into smaller install.swm

    Although windows setup does not support split wim files (.swm)

    you would be better off - doing a normal installation of windows..
    then register your current 5GB install.wim as the recovery image.
    then refresh the pc to apply your changes

    Thanks a lot. This method sounds promising. Can you please tell me how to mount the install.wim as recovery. Steps or a link please.

    create a "RecoveryImage" folder on your C:\ drive ( C:\RecoveryImage ) and copy your install.wim into that folder
    then run this command from command prompt(admin)

    Reagentc /Setosimage /Path C:\RecoveryImage /Target C:\Windows /Index 1

    then use the right charm bar to get into recovery and select the REFRESH option

    You should also be able to use Rufus, as it enables booting NTFS through UEFI, regardless of your UEFI system.
    The steps are:
    1. Select your Windows installation ISO, by clicking on the disk icon
    2. In "Partition scheme and target system type", select "GPT partition scheme for UEFI computer"
    3. The file system should already be set to NTFS, but if not change it to NTFS
    4. Click Start


    If you do that, you should be able to boot your Windows image in UEFI mode, even as it contains a >4GB install.wim file.

    Thanks for the reply. My BIOS is not recognizing NTFS bootable USB. Only FAT32.

    It doesn't matter what your BIOS can recognize. Rufus creates a FAT32 partition that loads an NTFS driver, so that it will be able to boot NTFS regardless of whether your BIOS natively supports NTFS or not.

    Can you please at least try? I'm pretty sure you will find that it works just fine, and I'm confident that using Rufus is really the easiest method to install a Windows ISO that has a large install.wim file.

    The only caveat is that you may have to temporarily disable Secure Boot for the install to work, but you can re-enable it aftewards.
