    i am reserrecting an old dell Inspiron 600, with Win7 Home Premium, with a Atheros 1506 internet adapter(IA). when i updated BIOS, drivers and OS, I lost the IA because of digital signature issue (Code 52). Your step by step solution ended a week of loading/unloading, enable/disable h/w as well as drivers as directed by dell support assistant, and some 'experts' in MicroSoft. now, it is millertime, thanx

    My solution, if got w7, upgrad w10, free, then crash, check this, devicemanager, show hiidden drivers, go to jraid ,sys, set automatic, (worked for me) or deactivated, No more probs.
    To mount a black/blue screen, hold f4, then go to f8, hold, then choose shut of driver forced …ok?

    Does anyone know how to get into the F8 or F7 menus on a Surface Book if the keyboard isn't responding?

    Or how to ensure the Surface Book boots from bootable USB? I changed the boot order in the UEFI, but it still won't boot from USB

    When performing solution 1, I get to step 7, but every time I press 7 or F7, it just automatically restarts my computer and wont proceed to step 8? I have followed your steps and multiple times, and it occurs every time.

      @Jacob winckowski: After pressing the “F7” (or the “7”) key, your system should reboot (it is normal). When Windows starts, proceed to step 8 and install the unsigned driver.

      @helpmeSAVEME: Uninstall the 'Voxal Voice Changer' program and then restore your computer to a previous working state.

    I have been trying to install W7pro on to a laptop with 8.1 which automatically upgraded to W10. It seems that W10 will not be overwritten.
    Neither your solution 1 or 2 worked and this is the message I get:
    C:\WINDOWS\system32>bcdedit /set testsigning on
    An error has occurred setting the element data.
    The value is protected by Secure Boot policy and cannot be modified or deleted.

    Your advice would be greatly appreciated.

      @Actionaunty: A. Disable the Secure Boot option in BIOS settings. (This option is usually in either the Security tab, the Boot tab, or the Authentication tab).
      or
      B. From Windows: 1. Hold down the Shift key and click Restart. 2. After PC restarts go to: Troubleshoot > Advanced Options: UEFI Firmware Settings and find the Secure Boot setting and set it to Disabled.
      After disabling the secure boot try install the unsigned driver or delete all disk partitions and perform a clean Windows installation.
      Good luck!

    I think the correct comand to DISABLE completly driver signature (metod 2) is:

    bcdedit /set testsigning OFF

    And, of course, in Windows 7 be sure to run the CMD promt as an administrator…

    I'm sorry but I tried both solutions and does not work. I had an HP notebook with Win pro 7. Having Motherboard problems. Went out bought Lenova ideapad 300 with Win 10. I want win pro 7. I successfully partitioned the C drive. Went to install win pro 10 from disc. Goes thru 1 & 2 and then goes to restart and get error message about the signature verification. Have tried mat least 6 times now and same error. I tried the method for win 7 and for win 10 and same results. What else can be done?

      @Judy M: 1. Create first the LENOVO recovery disks (for backup reasons) and then 2. Boot from the Win7 install disk and start the Windows installation. 3.Delete all the partitions on the disk. 4. Select the "Unpartitioned" space to install Windows. 3. When asked DO NOT enter a serial number and finish the installation.
      From Windows: After installing all the drivers needed for your system, try to "Activate Windows" automatically (enter the Serial number and activate) and if you have problems with automatic activation: Click Start and in the Search box, type: "slui.exe 4" (without quotes). Select your country and click the "Phone Activation" option and activate Windows by phone.

      @Abhishek: Press F8 to enter to Advanced options menu and select to boot to "Last Known Good Configuration" or Select "Disable driver signature" and then from Windows disable the driver signature completely (Solution 2 on this post).

    Sorry, but when I press Restart in the Startup Settings it say that I need to enter a Recovery Key or something like that… (Im using a Surface RT).

    ¿What is that and what can I do?

      @CeuxDruman: I don't understand what you mean. But, if you have problems with solution-1 try solution-2.

    windows does not have enough information to verify this certificate

    What about this problem on installed drivers?

      Ignore this error and just install AMD drivers. I think it is not an important error!

    I'm not good at computers and these software stuff but I happen to encounter this "cannot verify" notification when I tried to download a software so I searched google and it lead me here.

    I tried to do the 'Solution 1' to minimize potential risks but I have a problem when I typed the "shutdown /r /o" because nothing happens. I'm wondering if I typed the wrong command or there's just something wrong. I use Windows 7

    Hello, I miss more than 1 hour for this problem…I FIXED only then CHANGED in The BIOS settings in "Security" section "save boot" from enabled To DISABLED. (I recommend in bios to look in the right screen for more details and cereafull read something like "Signature", "Software security boot". by this time I use Toshiba, but I hope should work with others laptops too) good luck.

    This is a very nice article and gives in-depth information. Thanks for this nice article, which is a really good to read. I must admit that you are one of the best bloggers I ever saw. Thanks for posting this informative article, which is an excellent example of Windows cannot verify the digital signature for this file. I really appreciate it and I think people will like you.
