    How to Install Windows 8 or Windows 8.1 using the "Unified Extensible Firmware Interface" (UEFI)


    information   Information
    Systems that are built using Unified Extensible Firmware Interface (UEFI) are more likely to achieve very fast pre-boot times when compared to those with traditional BIOS. This isn’t because UEFI is inherently faster, but because UEFI writers starting from scratch are more able to optimize their implementation rather than building upon a BIOS implementation that may be many years old.
    Delivering fast boot times in Windows 8 - Building Windows 8 - Site Home - MSDN Blogs

    This method can also be used for the UEFI installation of Windows 7, Windows Server 2008 SP1, Windows Server 2008 R2, and Windows Vista SP1.

    Note   Note
    You will need to satisfy the following requirements in order to proceed:

    • A Windows 8 compatible system
    • A Windows 8 64-bit installation media. 32-bit is not supported.
    • A UEFI v2.0+ compliant PC. Check your chipset manufacturer/firmware documentation.
    • A blank, partition-free, hard disk for installation.

    warning   Warning

    • Disabling UEFI will make the system unbootable as there is no MBR on the disks.
    • You CANNOT make a sector-by-sector copy of GPT disks. The Disk and Partition GUIDs will no longer be unique. This must never happen. You can make a sector-by-sector copy of the contents of ESP or basic data partitions.




    Here's How:

    1. Do step 2 or 3 below depending on what installation Media you are using.

    2. If using a 64-bit Windows 8 or 8.1 Installation DVD with UEFI

    A) Insert the DVD, restart the computer, and go to step 4 below.
    NOTE: If you are unsure that your 64-bit DVD has UEFI support, then see OPTION TWO here: Windows 8 and Windows 8.1 ISO - Download or Create

    3. If using a 64-bit Windows 8 or 8.1 Installation USB Flash Drive with UEFI

    A) If you have not already, you will need to create a Windows 8 or 8.1 installation bootable USB flash drive with UEFI from either a Windows 8 installation ISO or DVD.

    B) Connect the USB, restart the computer, and go to step 4 below.



    4. Press whatever key (ex: F11) it shows to boot to your motherboard's boot menu, and select to boot from the listed UEFI DVD or UEFI USB. (see screenshot below)

    5. Do steps 2 to 7 in the tutorial at the link below, and return.
    6. Delete all partitions/volumes on the disk # (ex: Disk 0) that you want to install Windows 8 as UEFI on until that disk # shows as unallocated space. (see screenshot below)

    7. When you are finished, click/tap on New, Apply (for full size of disk), and OK. (see screenshot above)

    8. You will notice that the disk has now been formatted as GPT with 4 partitions. Select the "Primary" partition 4, and click/tap on Next. (see screenshot below)
    NOTE: You might receive a "Windows can't be installed on drive 0" warning, but as long as you can click on the Next button, you're fine.

    Note   Note
    The 4 partitions are:

    • Paritition 1 - Recovery
    • Partition 2 - System - The EFI System partition that contains the NTLDR, HAL, Boot.txt, and other files that are needed to boot the system, such as drivers.
    • Partition 3 - MSR - The Microsoft Reserved (MSR) partition that reserves space on each disk drive for subsequent use by operating system software.
    • Partition 4 - Primary - Where Windows is to be installed to.

      It is imperative that these 4 partitions remain in the exact order as they are

    9. You can now finish doing the steps in either tutorial below.



    10. That's it. You have successfully installed Windows 8 on a UEFI system.

    Windows 8 Dev Preview with Tools has a file bigger than 4GB so it cannot be stored inside a FAT formatted USB stick.
    And if we format the USB stick with NTFS the UEFI BIOS wont boot from it.

    How can we install "Windows 8 Dev Preview with Tools" UEFI mode using a USB stick?

    Try splitting the install.wim file

    I have the same issue on a macbook pro early 2011. I used Imagex to split the install.wim into several install.swm files (supported uder windows vista and 7), and move the boot files to the efi\boot folder, but I am getting stuck at the Product key page. All the product keys in the product.ini do not work, as well as the product keys given by microsoft for the reinstall option. I will continue on.

    I now have the installer running through the install, but fails when it tries to write to the mac boot sector. I had to redownload the iso, and resplit the files.

    Strange, I remember being able to boot from an NTFS partition. Not a USB stick, but a seperate partition with the installation files on it and installed from there.

    Also, shouldn't you be able to skip the Product Key page anyway?

    And about failing to write to the mac boot sector, are you sure the drive you installed it in is blank? Win8 would usually write the boot files as soon as you select a drive for installation.

    The UEFI spec calls for fat32 partitions being readable, not ntfs. When formated as ntfs, the usb stick would not be detected by the Mac UEFI. I did not use rEFIt, as I have been having issues with lion. (refit does not solve all the problems, I usually get an error when using it, at least from the windows 8 boot options)

    I have tried with the drive clean, with the drive pre partitioned according to the Microsoft requirements for uefi, and with OSX installed. In all cases, windows 8 gives me the message "Windows could not update the computer's boot configuration. Instalation cannot proceed."

    When searching the log messages located in the $windows.~bt and $windows.~ls (I don't remember which one right this second), I see a general error code, that I forgot to save. When searching online, I found similar error,numbered 81, not the 35 that I was getting that seemed to be driver issues, so I don't know if this one is a driver issue, or what. I have settled on using bootcamp for now, until I feel like working on this again. Bootcamp is working ok, with random system crashes.

    I think if I kew a lot more than I do about the microsoft boot environment, I could probably seperate the boot settings out into a fat32 boot partition, and them install from a ntfs partition, but this is seriously becoming a headache. I have worked on this for two weeks, having to wipe and restore the whole system countless times. I now hate the windows install screen. I am wondering if i may be able to use imagex to apply the install image directly, setting up the individual partitions myself, and making it work, I just don't know what files go where in the microsoft system partition, and which files are directly needed for the EFI partition.

    I should note, after installing windows the way I described in the earlier post, then getting that error message, when I reboot, I am able to hold down option/alt and boot into the UEFI Boot option, and get a windows error. It says that the recovery tools are not installed, and I must use my disk or usb stick to boot into it.

    If anyone has suggestions, I am all ears.

    Thanks.

    Hmm.. Which mac do you have, by any chance? Not the OS version, but the actual mac product?

    Just to add a couple of facts that I know that I'm trying to piece together in regards to your problem:

    For Windows:
    Can only boot from UEFI through a GPT disk on a UEFI 2.0 64-bit implemented firmware
    This is because only the 64-bit versions of Windows are designed to be booted from UEFI

    For Macs/Apple:
    • *Macs uses EFI 1.1 32-bit mode for most of its OSX Tiger and Lepoard. It was fairly recent (2008-9ish maybe?) that they implemented 64-bit EFI.
      *I can't say for sure if the even newer ones already implemented UEFI 2.0.


    Doing some research, this post from Apr 2010 (https://discussions.apple.com/thread...art=0&tstart=0) stated:

    Unfortunately, the 2010 MBP (at least the Core i7 version) seems to still be using EFI 1.1. I checked by booting to rEFIt ... the Mac doesn't use UEFI 2.0 ...
