How to fix the boot menu of Win7 dual system

Considering the stability and compatibility of Win8, I believe many people are equipped with Win7 and Win8 dual system, but after installing it, you will find that the boot menu will bring many problems. In order to help everyone better, share the situation with you here, write this article in order to help more people to take less detours, the methods in the article are pro-test. This method is applicable to Win8's full line of products so far.

First talk about two possible situations:

A. First install Win7, then install Win8

Bad consequences:

1. Win8 is the default system after booting. If Win7 is selected, it will be restarted and then enter Win7

2. Once Win8 crashes, there is no system disk boot, even Win7 can't enter

Analysis Reason: 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 starts, so it will be skipped directly.

Solution:

1. The principle 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 bootsect to fix. You can fix it in 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 the quick start function. of. 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 operating system display text you can change it yourself in Win7 optimization master, this requires netframework3.5 environment, my Win8 installed 3.5, no children can run under Win7, modify the operating system Display text, I modified 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 quick start in the power option of the control panel. Because only this is the real shutdown, the boot menu in front of the Win8 icon will be displayed. Otherwise, you will still enter Win8 directly, and no boot 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 Win7 does not need to restart once, and then go to the control panel to open or run powercfg -h on is also OK.

2. Run cmd (by Vista primary school) as an administrator under Win7, enter:

bcdedit /export c:\\bcd_backup

bcdedit /default {current}< Br>

bcdedit /displayorder {current} /addfirst

bcdedit /timeout 30

B. Install Win8 first, then install Win7

Solution: Relatively good solution As long as Win8 is set as the default startup item, then the Win8 system can be turned off just like the A case.
