How to set the computer to enter the operating system by default

As operating system versions continue to evolve, dual-system and even multi-system start to emerge in computer users' computers. Computer boot will appear when you choose to enter the system options, if every time to manually select will be very troublesome, how can we use a once and for all ways to make it automatically by default into a system?

Click the Start menu, right-click the right computer option, open the properties.

Then open the properties page on the left of the advanced settings options.

Click the Settings button pointed to by the arrow in the Advanced System Settings page.

At this time there will be such an interface below, that is, choose the operating system interface.

Click on this drop-down menu and all the operating systems you have installed on your computer will appear. Click on the system option you want the computer to enter by default, where I click the default boot into windows7 system. Finally click OK to exit.

Finally click OK to exit the setup process.

Well, this time when you boot up again, the system will no longer appear a choice to enter the operating system steps, and direct access to your choice of system. This is also to some extent saved us boot time.
