Win7-win8 dual system boot menu repair method (into win7 do not need to restart)

(Effect: repair the dual-System menu (win7 and win8). You do not need to restart Windows 7. The normal menu style is more concise and practical. You can select the operating system when you start the system .)

Considering the stability and compatibility of win8, I believe that many people should be installed with the same win7-win8 dual system, but after you installed will find that the boot menu will bring a lot of problems. To help you better, I will share with you the situation I have encountered here. I wrote this article to help more and fewer people make detours. All the methods in this article are tested by myself. This method applies to all products of win8 so far.

First, let's talk about two possible situations: www.2cto.com

A. Install win7 first and then win8.

B. Install win8 first and then win7.

In case A, you will undoubtedly get the result of the metro boot menu, which has two disadvantages:

1.
After the boot, win8 is the default system. If win7 is selected, it is bound to restart and enter win7 again.

2.
Once win8 crashes, there is no system disk boot and Windows 7 cannot be accessed.

First, let's analyze the cause of this situation. As we all know, win8 has introduced the Quick Start function. The official statement is to store the information required for starting some systems in a file, calling directly after power-on saves a lot of time. But the essence of correction is actually sleep. This is why the metro boot menu appears after the win8 icon is displayed, rather than before it appears. Because the Quick Start is enabled by default, the boot will not directly read the boot, instead, the system will be started first. If the boot menu is placed before win8 is started, it will be skipped directly. Www.2cto.com

After analyzing the cause, let's talk about the solution: the solution is to fix the metro menu into a normal menu that starts when it is started. I personally use BCDautofix v1.23 (BCD ), of course, you can also use bootsect of win7 to fix it. You can fix it in win8, but it turns out that if you use it in win8, a false shutdown may occur, and the power indicator will not go off. After you press the keyboard, you will return to the login interface, the reason should be the nature of quick start. Therefore, we recommend that you perform advanced win7 repair. After the automatic repair is complete, run the msconfig command to go to the boot tab of the system configuration and modify the default system and wait time.




You can change the display text of the operating system in the Windows 7 optimization master. This requires the netframework3.5 environment. In win8, 3.5 is installed, and no children can run it in Windows 7, modify the operating system display text. I modified Windows 8 and Windows 7. The display is concise, and the order of up and down can be adjusted. I put Windows 8 on it.



This is basically done, and then enter win8, press win + X to run the command prompt with administrator privileges, enter the command powercfg-h off, or manually turn off the Quick Start in the power option of the control panel, because only in this way is the real shutdown, the boot menu in front of the win8 icon will be displayed. Otherwise, the system will directly go to win8 without showing the guide. In fact, there is no way to turn it off, but it takes about 10 seconds to slow down, and the total time is about 30 seconds. This will not have a big impact, but win7 does not need to be restarted once, you can also open the control panel or run powercfg-h on when necessary.

In case B, the solution is much better. You only need to set win8 as the default startup item, and then turn off win8 for quick start as in case.
