Win7-win8 dual system boot boot menu repair method

(effect: repair dual system menu (win7 and win8 dual system), enter win7 no longer need to restart, normal menu style, more concise, practical, boot can choose operation System.)

Considering the stability and compatibility of win8, I believe many people should install the win7-win8 dual system like me, but after installing it, you will find that the boot menu will bring a lot of problem. In order to better help everyone, I am here to share with you the situation I encountered, this article is written to help more people take less detours, the methods in the article are pro-test. This method is applicable to the whole line of win8 so far.

First talk about two possible situations: A. First install win7, then install win8B. First install win8, then install win7

A situation, then everyone will undoubtedly get the result of the metro boot menu, this menu has two shortcomings:

1. Win8 is the default system after booting If you choose win7, it will definitely restart and enter win7

2.win8 Once it crashes, there is no system disk boot, even win7 can not enter

First, analyze the cause of this situation As we all know, win8 introduces the function of quick start. The official statement is that some of the information needed for system startup is stored in a file. It is saved directly after booting, which will save a lot of time. But in fact, to correct its essence, it is actually dormancy. So this is why the metro boot menu appears after the win8 icon is displayed, not before this, because the default quick start is turned on, then the boot will not directly read the boot, but will enter the system first, if The boot menu is placed before win8, so it will be skipped directly.

After analyzing the reason, then talk about the solution: the method is to restore the menu of the metro to the normal menu that is started at boot, I personally use BCDautofix v1.23 (BCD), of course you can also use win7 The bootsect to fix it. You can fix it under win8, but it turns out that under win8, there is a certain probability that there will be a false shutdown phenomenon, the power indicator will not go out, and the keyboard will return to the login interface after knocking the keyboard. The reason should be the nature of quickly starting this function. Caused. Therefore, it is recommended that everyone still be advanced win7 repair, after the automatic repair is completed, you can run the msconfig command to enter the system configuration boot label to modify the default system and wait time.

As for the display text of the operating system, you can change it yourself in the win7 optimization master. This requires the netframework3.5 environment. I installed 3.5 in my win8. The children who are not installed can run under win7. Modify the operating system display text, I am modifying windows8 and windows7, the display is simple, the upper and lower order can be adjusted, my is to put windows8 on it.

This is basically completed, 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 power option in the control panel Quick start, because only this is the real shutdown, the boot menu before the win8 icon will be displayed. Otherwise, it will still enter win8 directly, and no guide will be displayed. In fact, it is not awkward to turn off, just about 10 seconds slow, the total time is about 30 seconds, it will not have much impact, but the startup of win7 does not need to be restarted once, and when necessary, go to the control panel to open or run powercfg -h on is also OK.

B situation, relatively good solution, as long as the win8 is set as the default startup item, and then the same as the A situation, turn off the win8 system to start quickly
