    windows 10 opens the 'what to do with this' popup everytime Rufus initializes the USB device, which causes a fail.
    how do I suspend that operation in 10 so it does not feel the need to access the usb?

    Hello Techwest,

    For Windows 10, see the tutorial below instead.

    Disable CSM, but then you will need to reinstall Windows 7.
    but when I disabled CSM during the installation, the bcd error 0x00000d just came out and I couldn't install windows. SO that's why I opted to enable CSM during my installation yesterday. And I remembered that it's in the "downgrade windows 8 to windows 7 " tutorial that I learnt to enable CSM. Isn't it? Or I just got it completely wrong at the beginning?
    To run in UEFI GPT mode you have to install UEFI here is a link on the 7forum that should help you understand how its done.

    I have to repeat, that I have followed the tutorials on both the seven and eight forum beforehand, but since the bcd error occurred, I had to enable the CSM. I just want to know why would the bcd error occur. And I follow this tutorial:Downgrade Windows 8 to Windows 7
    which told me to enable the CSM. Where did I do wrong?

    Enabling CSM allows BIOS MBR boot and would install your OS in BIOS MBR.
    This Tutorial explains pretty well how to modify the Windows 7 SP1 ISO to boot UEFI, It also explains how to use diskpart to clean and convert your disk/SSD to GPT. If that one doesn't work for you Bink has a link to his tutorial in the reply's to this thread, which is a little more through. These tutorials do work so unless you have some sort of hardware issue?
    The tutorial tells you to disconnect any drives that you are not installing the OS too. you need to do this all you should have is your modified Win 7 SP 1 ISO created to a USB Install media and the hard drive you are installing the OS on..

    Hi all, I'm sorry to revive a fairly old topic but I don't know where else to turn. I just received a brand new Clevo P650RE laptop with a proprietary BIOS and I'm trying to install Windows 7 64-bit using the tutorial on the first page of this thread. I followed every step and I'm running into the same issues as some other folks on here, the dreaded 0xc000000d error. A lot of the fixes revolved around enabling Launch CSM and/or disabling Fast Boot and Secure Boot options in BIOS. The problem is I'm missing the Launch CSM and Fast Boot options, and Secure Boot is already disabled.

    I would really appreciate any advice you may have, thank you.

    Hello Adrian, and welcome to Ten Forums.

    Have you already tried installing Windows 7 without UEFI?

    Hi! No, I have not tried Windows 10, I'm trying to install Windows 7 64-bit.

    EDIT: I guess you meant Windows 7 I just tried it with UEFI Boot disabled and the USB drive wouldn't even boot up. Do I need to create a different USB drive for a non-UEFI Windows 7 install?

    EDIT: I just tried it on another PC that had UEFI Boot, CSM, and Fast Boot options in BIOS. I set UEFI Boot and CSM to enabled, and Fast Boot to disabled and the installation worked just fine. Sooo, I guess it's the BIOS in my laptop that is not allowing the installation to proceed... What am I supposed to do now?

    I'm trying to create a non-UEFI install USB and will attempt the installation again with UEFI disabled. Are you saying that it would be my only option seeing as how the BIOS doesn't give me CSM and/or Fast Boot options?

    EDIT: I am able to install Windows 7 from a non-UEFI USB media... So, does this mean my laptop's BIOS does not support a Windows 7 UEFI install because of missing options?
