Remove unwanted boot menu from Windows7 system

If installing Windows 7 is an overlay installation without formatting C disk, Setup prompts you to keep the original system as a folder, but you cannot log on to the original system! I deleted the folder and freed up the hard disk space. But now every time the system login interface to select the system to enter, one is Windows 7, one is the original system. How do I get rid of the boot menu and go directly to Windows 7?

There are two ways to solve this problem. are graphical interface methods and command-line methods respectively.

Graphical interface methods:

Click "Start → run" in turn, enter Msconfig and make sure that the boot menu option can be modified in the Boot tab.

Command-line method:

Run the command prompt in administrator mode and use the Bcdedit command to modify the name of the Windows 7 menu item: Bcdedit/set {default} description "Windows 7".
