    Windows 8 BSOD 0xc0000034 and BSOD 0xc0000001 (Laptop)


    I have a clients Laptop (Asus X550C) running Windows 8 and the first error I had was 0xc0000034, having a look around I tried some fixes but none worked, eventually I was left with the following error: 0xc0000001. As of now I am stuck here, I have a backup of the main files the client needs but do not want to reformat as I do not have their product key (It is not listed on the laptop and I cannot boot into the OS to run a key extractor).

    Here is my documentation of the steps I followed:

    TURN ON LAPTOP:

    Recovery

    Your PC needs to be repaired

    The Boot Configuration Data file is missingsome required information

    Win8.1Pro - Finally!!!


    I understand that this is a very important problem for you and that you'd like it solved as soon as is possible. But there are other circumstances that you may not be aware of. Please read this pinned topic about waiting for a response: Have you been waiting for a response?

    Try turning Secure Boot off (or, if it's off, try turning it on). This should be separate from the CSM setting.

    I'm going to try to restore an Win8Pro HP today with a retail copy of Win8Pro (it had a failed HDD). I suspect that it'll install w/o problems - but want to be sure before recommending the same to you.

    EDIT: As I recall, the product key is encrypted in the UEFI (on systems that came w/Win8 or 8.1 installed by the OEM). When installing Win8 it'll look in the UEFI and decrypt it

    Win8.1Pro - Finally!!!


    I successfully installed Win8Pro on an HP laptop that came w/Win8Pro - and I used a DVD of a full retail copy of Win8Pro
    I verified activation using this article: How to Confirm that the Windows 8 System is Activated Successfully
    At no time was I asked for the product key (the system was connected to the network when I started).
