    So, I am trying to install Windows 8 with UEFI support.

    Which means file system can only be fat32 because UEFI doesnt support NTFS. Now my install.wim file is over 4GB in size, so I am unable to copy it to the usb drive because of fat32 limitations.

    How would you go about this ?

    I tried creating 2 partitions on my usb. One fat32 - which contains all boot data and second partition is NTFS which has only my install.wim file.

    Now I am able to boot, but it doesnt detect my install.wim obviously because it is in another partition. What command should I use to pull it from another directory ? I am able to open CMD on the set up screen.

    OR any other way to accomplish this ? How would you go about this ? Please help.

    Thanks a lot in advance.

    First create a new folder called c:\wim
    copy your install.wim to that folder
    This command only works within windows 8 use this command to split your install.wim then copy all files to your source location on your iso or usb. remember to delete the original install.wim fom your installation source, and then run windows 8 setup

    What's about the use of xFat? xFat could be used for FAT files bigger than 4GB and could used from XP S2 onward, Server 2003 up to the latest OS which seems to be Windows 8.1 Pro Preview at this very moment!

    exfat and uefi

    Hi pisthai and everyone else

    The ExFat filesystem idea it's actually good, except UEFI only boots from fat32 drives. And bootsector or MBR from fat32 and ntfs too, windows doesn't like booting of ExFat drives, Exfat kicks it on my external drive. Less writes and reads lasts more too :) The pendrive to setup either windows or linux work all good by formatting in fat32 and setting it active with diskpart.
    about the 4gb files I'd try to reduce sources.wim size by removing some big drivers like nvidia or amd and/or removing some big updates till it goes down to 3.5GB 3.6GB max.


    Off-topic: IMHO I'd rather install untouched and then go take a walk, smoke or anything while the 100 and something updates install. I know it takes forever, Windows setup: 10 mins, updates, more than an hour and half (m5a99x EVO Mobo, FX 8120 CPU 8GB DDR3-1600 and a regular SATA hard drive).

    Hope this info helps,

    nice forum and have a good one!

    Noop, he just want to say Rufus can create UEFI compatible bootable pen drive. But it can't help you in the current situation.

    this install.wim is 7 gb in size. I don't know how can I reduce it to less than 4 gb. I heard its possible to pull install.wim from another directory, I just want to know how. A tutorial, dism command, anything would be appreciated.

    You have 2 options
    either split the wim
    2- boot windows from windows PE4 and once you boot it go to cmd and type notepad
    in note pad open the usb where your set up is or best keep a folder called win8 for easy access under c:\win8 and run it from there it will let you install from there i have done more than 50 times never5 had any issues

    Google windows pe4 for uefi the iso is very small and can be copied on a 1gb usb flash
    other options can be
    use GimageX to install your wim and once done
    go to CMD (admin)
    type

    bcdboot C:\Windows /s F: /f ALL ( F: being your new partition where you installed windows)

    if any problem
    you can add new partition to windows manager
    The following example merges the operating-system loader in the current BCD store that the specified GUID identifies in the new BCD store:
    bcdboot c:\Windows /m {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} (xxxxxxxxxxxxxxxxxxxx) being the GUID)

    there are many more ways other to install windows

    He needs to do an UEFI/GPT installation. This setting is applicable for BIOS/MBR installation.

    sorry if i was not clear. your best approach is to split the wim into swim using the video above then you will be fine.

    i tried it, doesn't work. It says - " windows cannot find the Microsoft software license terms. Make sure the installation sources are valid and restart the installation"


    so, it doesn't allow installation from split .swms as Tito pointed out.
