Win7 system boot occurs with 2 or more system booting how to remove

The reload system has two windows7 startup options during startup, or one of the other multiple boot options! As shown in the first one is accessible to the system, and the second is inaccessible, so how does the Win7 64-bit flagship remove this unwanted startup option?

First, press the Windwos+r shortcut key to open the Run window to enter "msconfig" and then click OK.

Second, select the boot option in the Open System Configuration window. As shown in the figure, you can see multiple system boot booting.

Third, choose the unused system boot options, and then click Delete.

Hint: As shown in the figure after the first option "Current OS, default OS" is the current system boot boot, can not be deleted, delete will cause the system can not start!

After restarting the computer, you can see that the Win7 clean version of the redundant system boot boot option has been removed.
