If you are the main Win8 dual system, start to select the system, select the bottom: change the default value or select other options — select other options & mdash; troubleshooting & mdash; advanced options — Windows boot settings — restart, and then disable the driver mandatory signature, you can solve the problem of mandatory signature. There are children's shoes to ask at the back, I am not a dual system how to do?
Xiaobian found a look on the Internet, sorted out a collection of solutions, with maps.
Note that this method is only valid once after the operation. If you need to install other drivers, you need to repeat the following steps.
Simple text version:
1. If it is Win8 (main) dual system, when starting to select the system, select the bottom: change the default value or choose other options ——>select other options ——>Troubleshooting——>Advanced Options——>Windows Startup Settings —Restart, then select “Disable Driver Forced Signature>;
2, if you are not Win8 (main) dual system, or Win8 single system, after entering the system, [Win] + [C] call out Charm menu - change computer settings - settings - regular - advanced startup, immediate restart - troubleshooting - advanced options - Startup Settings - Restart, then disable the driver to force the signature.
Find the method on the Internet, share: When booting, press shift+f8, select the disable driver in the system startup menu to force the signature mode to start, you can install it. —— This seems to be invalid. I didn't press it to start the menu. I can try it a few times if I need it.
Illustrated version:
1, operating system: Win 8 Pro x64
2, the device is a long time ago scanner, the driver has not been updated, but there is a Vista driver, And it is an inf file, so you can change ntx86 to ntamd64, before passing the test on Win 7 x64!
3, unexpectedly in Win 8, "The third party INF does not contain digital signature." Information & rdquo;, then there is no need to continue — & mdash; not to install!
The following is the solution, in order to facilitate reading, continue the above serial number:
4, Charm menu (that is to install Win8 Show the operation method behind you, shake the menu that will appear when the mouse is in the corner of the right side of the screen; if you feel that the students who are not swaying directly press [Win]+[C], you can call up the Charm menu) The full-screen menu on the side, find the settings inside.
5, there is a change in the computer settings,
latest update: press [Win] + [i] You can open the settings directly without the 4th point above.
6. After turning on the computer settings, select General on the left, then select the last item on the right to restart immediately. Yes, it is to change the Windows boot settings from here.
7, the restart here is super fast, even the POST of the boot self-test did not see, just switch it! It feels like playing chicken blood!!!--!
8 Here, choose the troubleshooting
9, here choose the advanced options, in fact, there are many other options (such as initializing the computer?), you can see it on the line, not the focus of this article, so skip it.
10, here choose the startup settings, in fact there are many other options (such as the command prompt, this many uses).
Remarks: Here is a special command prompt. I used to restore the system with ghost before, but found that x64 Win8, this place can not run 32-bit Ghost32.exe program, you can use Ghost64.exe. This is equivalent to PE, and may be related to this. The x64 desktop environment is operational.
11. Here is the real restart~ No wonder it was so fast, it turned out to be fake~ The screen switched a bit!
The latest update: Here is another time to restart! !!!
Before a picture is missing, some brothers did not realize that the following 12.1 and 12.2 are the boot menu!
Two situations: 12.1 is the Win8 main system, 12.2 is the multi-system and Win8 is not the main system .
1.1, if your Win 8 is the main system or a single Win 8 system will see such an interface, select 7 - disable the driver to force the signature. I am pressing the small number keyboard, and watching the screen says that F7 is also OK.
12.2, if your Win8 is not the main system, select Win8 and press F8 to see such an interface, select “ Dlsable Driver Signature Enforcement & rdquo; continue to start. With this menu system version is different in different languages, Chinese word is & ldquo; disable forced driver signing & rdquo;
13, enter the system
14, which erupted update The driver finally saw the legendary Windows security dialog
15, successfully updated the driver!
The method has been determined to be invalid:
1, user configuration in the group policy - management template - System-Driver Installation-"Device Driver Code Signing> Double-click, set to select “enabled"," When Windows detects a driver file without digital signature, “, select “ ”, OK.
2, Cmd in administrator mode, enter:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit /set testsigning on
latest updates: This command is I have only recently contacted and listened to everyone saying that it is a test mode. It also causes the already activated system to be watermarked.
Because the system was not activated before, there is no way to judge. Today, I saw the Kms of Jiaotong University in the forum, activated the system, and did see the watermark in the lower right corner.
And again, the test mode is unable to force the driver to sign, there is a picture for the certificate!
3, about the function of pressing the F8 key to enter the boot menu, what F8, CTRL+F8, Shift+F8 It's useless! If you want to enter, you can only change the computer settings from the settings in the Charm menu. Here you will enter the boot settings.
The methods provided in the above forums, after actual testing, are invalid under Win8 (x64).
Xiaobian summary:
As a new Windows operating system, Microsoft's move has undoubtedly increased the difficulty of Win 8 driver support. Not to mention Win 8, even Win 7, at least 40% of my computer is not Whql driver, so I specifically studied this method. Time hastily, there are not good places, I look forward to your comments and corrections. I look forward to a simpler and once-in-a-lifetime approach.
If you are the main Win8 dual system, when you start to select the system, select the bottom: change the default value or choose other options — select other options — troubleshoot & mdash; advanced options — Windows boot settings &mdash ; Restart, then disable the driver to force the signature; if you are not the main Win8 dual system, or Win8 single system, after entering the system, Charm settings - change the computer settings - settings - regular - advanced startup immediately restart - troubleshooting - advanced Options - Startup Settings - Restart, then disable the driver mandatory signature.
