    64-Bit system will only install 32-bit Windows 10. BlackScreen


    I recently had Windows 10 64-bit installed. Suddenly after a restart the only thing I could see after POST was a black screen. I was planning on doing a clean install of Windows 10 x64 anyway.

    1. Downloaded the x64 ISO and copied everything to a USB external drive.
    2. Set boot options in the BIOS to boot only from the external drive. Still same black backlit screen
    3. Push F8 at POST - continue to get black screen

    Determined that I must be doing something wrong I bought a 16gb flash drive.

    1. DOwnload MediaCreationTool.exe
    2. Create BOTH 32 & 64 bit install
    3. Boot to USB - Shows both options to install
    4. Select 64-bit - DIsplays loading bar at the bottom, light flashing on USB, once status bar finishes screen goes dark, No blue windows logo, NOTHING.
    5. Restart
    6. F11
    7. Install 32-Bit Version.. This works.

    In the bios my i5-4690k chip is recognized and 64-bit is listed as supported.
    In Windows the System Info shows 64-bit system with the 32-bit OS installed.

    Things I have done:
    Reset CMOS
    Format SSD to GTP (or what ever that is)
    Reset BIOS to Default
    Will not also that Safe mode start-up from POST is unresponsive.

    Memtestx86 results show no errors

    Specs:
    ASRock Z97 Pro4
    i5-4690k
    EVGA 600w
    16gb RAM
    MSI GTX970

    upgrade from 32 bit windows 10 pro to 64 bit

    The first item to check is to ensure your PC has 64 bit processor, if yes, to upgrade from 32 bit to 64 bit requires a 'clean install', you will need to purchase a Windows 10 Pro installation device (DVD).

    The current upgrade system will only install the bit version of W10 that is currently installed.

    Upgrading from 32 to 64 bit system can not be carried out by utilising the current free upgrade system, also upgrading from 32 to 64 bit system has always required purchasing a 64 bit installation device.

  3. Why is it so hard

    As I read your question, it appears that you have Windows 10 32 bit, and wish to change to 64 bit.

    The process as I understand it for the free upgrade is to check that your 32 bit windows 10 install is activated (to ensure Windows 10 will activate again on that machine). Then to create media "for another computer" (64 bit) boot from that media and do
    a clean install, setup can't be run from within a 32 bit system, only the 64 bit PE you boot into or a 64 bit OS.

    Trying to run 64 bit setup from within a 32 bit operating system gives the error you describe.

    There has never been a direct (in situ) upgrade path from any 32 bit windows version to 64 bit, a clean install has always been required.

    Next thing I would try is updating the BIOS for your motherboard. Go to ASRock's website and download the newest BIOS for your mobo model. If you still have the 32 bit Windows installed, update it from there. If not, going into your BIOS should give you an option to update the BIOS from a flash drive.

    I will try that again. Forgot to list that as one of the things I have tried.
    First going to revert back to the original one. See if that works then load the newest one.

    Could my Mobo &/or CPU be crap? Or am I just messing something up?

    Make sure the option for NX is enabled if that is a feature of your BIOS (which is really UEFI firmware, not BIOS) for the CPU.

    The NX was already enabled. Downloaded 8.1 x64 and looks like that is installing. Hopefully after that installs I can install a clean Windows 10 64-bit.

    Keeping fingers crossed. If you happen to have another idea I am struggling here.

    Confirmed install of x64 Windows 8.1 Pro.

    Going to try x64 Windows 10 again.

    This whole issue is so strange

    Ok. Here is where I am at. Installed 8.1 x64 using ei.cfg to load trial version. I can start the 10 update in Windows but now it asks me for a key. Which I don't have because it is tied to my CPU/mobo.

    Install from master boot still goes dark.
