Solution to the loss of windows startup items after centos7 Dual System

After centos7 is installed on windows 7 and 8/10, mbr is changed to grub2 by default. The default centos7 does not recognize windows ntfs partitions, so the startup item does not have windows.
You can use three commands to add a windows Startup item to grub2.

First, ensure that the Internet is accessible.

1. yum-y install epel-release2.yum-y install ntfs-3g3.grub2-mkconfig-o/boot/grub2/grub. cfg

The three commands run successfully. After restarting, you can see the startup items of windows 7 (loader) and enter windows.
