    I can't install Windows 8.1 on Asus Desktop


    INITIAL ISSUE: Could not boot

    Last week, I tried to dual-boot install Fedora Linux onto my Windows 8.1 PC (Asus CM1435 Desktop). I resized the Data Partition (not OS partition) by 100GB. I then restarted the PC, and Fedora seemed to work okay, however, I could not got Windows to start anymore. I then turned on Secure Boot and other Windows 8-optimized settings and tried to start up again; it did not work, Windows could not boot.
    I tried to search up some details on how to fix this problem, and I came across bcdboot and bootrec commands, and ran them (/fixmbr, /fixboot, /rebuildbcd), however, there was no luck, as /rebuildbcd gave me a 0 disks found error. I also followed the instructions here (https://neosmart.net/wiki/recovering...ws-bootloader/). At this point, "Windows Bootloader" disappeared from the BIOS. Restarting resulted in a "Missing Operating System" error.
    I tried using a Windows 8 installation disk, and tried Reset and Refresh, but neither worked. Reset gave me "Recovery Partition could not be found" (was still there, just got messed up in the resize or something), and Refresh gave me "Disk where windows is located is locked" (perhaps from fast reboot?)
    Then, I gave up all hope on the current installation. I booted into my Windows 8 recovery disk, formatted C:, and installed it from there. When it got to "Windows needs to restart to continue", restarting put me to "Missing operating system", and I could not continue the installation. I tried it again, (formatted and ran again), but no luck there.
    TLDR: Installing Linux broke Windows. Deleted Linux and could not reinstall Windows from repair disk. Formatted partition for Windows and used Win8 disk to reinstall, but errors.

    Current Issue: Cannot install

    Deleted all partitions except a factory recovery partition and a data partition. SYSTEM partitions and boot partitions were deleted.

    Put Win8.1 disk in, installed into unallocated space. After installation got to the "Restart Needed" part, PC restarts and does NOT continue installation. I looked at the partitions the setup installer made, and it seems everything is correct (MSR's, EFI boot partition, etc). However, PC won't boot from Windows Bootloader. My PC is on a GPT disk, UEFI BIOS. Windows Bootloader used to be listed in the UEFI menu, but now it is not listed, and cannot be booted to it. When I disable UEFI and boot, I get "Missing Operating System". With UEFI, it just says I need to disable it to boot.

    Please help, any help is highly appreciated

    Try this for a clean install.
    Booting and partitioning of GPT for Windows 8:
    1.Boot from the Windows 8 install media (You must initiate this boot from a device labeled as a UEFI device, or the installation of Windows 8 will produce an error that the OS cannot be installed to a GPT partition) These UEFI boot devices will have a prefix UEFI: "name of your device", and show as a boot option in your UEFI.
    2.After booting to the UEFI device you see the Install Windows 8 screen, press Shift + F10 to open a command prompt.
    3.Type Diskpart, press Enter
    4.Type List Disk , press Enter
    5.Type Select Disk # (where # is the number your drive shows up as), press Enter
    6.Type Clean, press Enter
    7.Type Convert GPT, press Enter
    8.Type Exit, press Enter.
    9.Close the Command Prompt window.
    10.Click the "Next" button.
    11.Click the "Install now" button.
    12.Put in your product key and click the "Next" button.
    13.Accept the terms and click the "Next" button.
    14.Choose "Custom: Install Windows only (advanced)."
    15.Select the partition and click "Drive options (advanced)"
    16.Click "New" and then click the "Apply" button. Four partitions should appear. Click the bottom partition.
    17.Click the "OK" button and then click the "Next" button.
    18.From then on follow the on screen instructions till you get to the desktop.
    Note: If you can't boot after the install you need to make sure the boot is set to "Windows Boot Manager" in the UEFI. Also, important info.

    I tried your instructions, but I get the same results, cannot boot into windows to continue setup. Windows is not an option in the BIOS.

    When you boot after the install hit which ever F key that brings up a boot menu, then select windows boot manager or your hard drive that has the Windows installed on.

    SOLVED!!!!!!

    I installed Grub from Fedora 20's UEFI images in UEFI mode, Index of /pub/alt/live-respins, then installed Win8.1 after Grub. This added Windows Bootloader to the BIOS and everything started working again. Thank you so much, Clintlgm! Everything ended up working, after all
