We select this option, and then follow the prompts to enter the Windows system recovery environment. In this environment, we can select the "Start Repair" option and wait for the system to automatically detect and repair the boot file.

This is a tool that allows us to control the system startup options, where we can add, modify, delete, disable or enable system startup options. First of all, we need to open the command prompt on the computer and then run it as an administrator. In the command prompt, we enter the "bcdedit" command to see the current system startup options. We can add or delete startup items here. For example, we can use the "bcdedit /delete { guid}" command to delete unwanted startup items. If we need to add startup items, we can use "bcdedit /crEate { bootmgr} /d "descriptive information" /application bootsector" command to add new startup items. Through this method, we can completely control the startup options of the system, so as to solve the problem of the dual Win7 system.
