    Trying to Install Unsigned Driver for DJI Flight Controller on USB


    This has been a known problem for 3-4 years as I search the internet for solutions.

    I have found several places that point me to instructions on how to boot my Windows 10 into safe mode or a mode that allows the installation of unsigned drivers. Every time I attempt to restart while holding the shift key, my computer goes into a circular reboot where it tries to "create a safe configuration" or some words to that affect. It will reboot sometimes dozens of times, and then either after I power off for several seconds or sometimes not, it will reboot to windows normally or the last know good configuration, I am not sure.

    But never can I get to a screen that allows me to choose what special boot conditions I need, like I find in many instructions for disabling driver signing.

    My computer is fast, because I have a SSD as the OS drive. As I am typing this, I wonder if the BIOS has the fast boot option selected. I am going to go ahead and post this and then go check that.

    One last thing, I was able to get the computer booted into Test Mode by starting a command line in administrator mode and typing Bcdedit.exe -set TESTSIGNING ON. However, I am about to turn test signing back on, because I really thought I lost the computer and was going to have to boot it from media but finally was able to get it to boot by rapidly hitting the F8 key. But Test Mode would not allow the driver to install. It still aborted in the middle of the install.

    Any help would be appreciated. Now I will turn off Test Mode and go to the BIOS and check the fast boot option. I hope it is something that simple.

    Unfortunately, I cannot get the computer to start in "Driver signing disabled" mode. Fastboot was on but that setting has been changed. The computer still goes in these strange loops when I try to boot this way, and then when I do get it started, it is back to standard mode.

    Has there been an update so that the driver signing feature cannot be disabled?

    You might need to clear secure boot keys from within your BIOS......this should allow you to install non-signed drivers......

    You might try this:

    Installing Unsigned Drivers by Disabling Integrity Checks
    To disable integrity checks:
    STEP 1: Open the Command Prompt as admin from the Power User menu, then execute the command: bcdedit /set nointegritychecks off
    STEP 2: After executing the command, restart your PC, and then proceed in installing the unsigned driver for your system.
    STEP 3: To re-enable integrity check, execute the below command as an admin in the command prompt: bcdedit /set nointegritychecks on
    STEP 4: When you get the message saying the operation was successful, restart your system and you’re good to go.

    There was a setting in BIOS that would not let me boot into Windows 10 until I allowed the BIOS to bypass the security feature. In other words in a corporate environment or similar where the BIOS is locked, you can prevent users from booting in the unsigned drivers allowed mode.

    Apparently the BIOS will keep rebooting until Windows clears itself of that mode and resets itself to disable unsigned drivers.

    I would never have looked there, so thank you very much!

    There is also a setting to clear secure boot keys, but I was afraid to do that thinking it would clear other drivers that I had a hard time configuring earlier.

    As you found out, you have to Disable Secure Boot in the Bios.
