Repair of boot guide menu for Win7/Win8 Dual System

Considering the stability and compatibility of Win8, I believe that many people are installed with Win7 and Win8 dual systems. However, after installation, we will find that the boot menu will cause many problems.

To help you better, I would like to share my experiences with you 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:. install Win7 first, and then install Win8 www.2cto.com. Adverse Consequences: 1. after the boot, Win8 is the default system. If Win7 is selected, it is bound to restart and enter Win7 2. once Win8 crashes and there is no system disk boot, it cannot be used to analyze the cause: As we all know, Win8 has introduced the Quick Start function, the official statement is to store the information required for starting a part of the system in a file and directly call it after it is started, which 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. Solution: 1. The principle is to fix the metro menu into a normal menu that is started upon startup. 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, there will be a certain probability of false shutdown. 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. 2. run cmd (by Vista primary school student) as an administrator in Win7. Enter: www.2cto.com 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 you set Win8 as the default startup item, and then as in the case of A, turn off the Win8 system to start quickly.
