Win7/Win8 dual system: repair boot menu has a trick

Many system users have installed Win7 and Win8 dual system, but installed a dual system and found the boot menu brought a lot of problems. So, today we will solve the problem of repairing the Win7/Win8 dual system boot boot menu.

First talk about the possible two situations:

A. First install Win7, then install Win8 Bad consequences:

1. Win8 is the default system after boot, if you choose Win7, is bound to restart and then enter Win7 2.Win8 once collapsed, no system disk boot, even Win7 can not enter the analysis reasons: As we all know, Win8 introduced a quick start this feature, the official statement is to start a part of the system The required information is stored in a file and is called directly after booting, saving 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, type: bcdedit /export c:\\bcd_backup bcdedit /default {current} bcdedit /displayorder {current} /addfirst bcdedit /timeout 30 B First install Win8, then install Win7 Solution: Relatively good solution, as long as Win8 is set as the default startup item, and then close the Win8 system with the same situation as A.

The above analysis of the two situations, and a detailed description of the solution, I believe that everyone has a better understanding of the Win7/Win8 dual system boot boot menu, if you also happen to encounter the above problems in the boot menu Then quickly solve the problem through the above steps.
