Boot problems when windows and Centos dual systems are installed on the computer, centos dual systems

(This article does not go into details about how to install windows and centos on your computer .)

When installing a dual-system on a computer, you must first install the windows system and divide an idle partition on the hard disk to install the centos System (you can install the centos System by Using "Apsara stack ).

After the centos system is installed, restart the computer and find that the system cannot choose to enter windows. After the centos system is installed, the mbr boot is changed to grub2 boot, while centos does not recognize the ntfs partition of windows, therefore, the startup item does not have windows.

Solution: first, ensure that the computer can connect to the Internet. In the centos system, enter the following command:

1. yum-y install epel-release

2. yum-y install ntfs-3g

Grub2-mkconfig-o/boot/grub2/grub. cfg

After the command is run, the windows Startup item is displayed.

4. modify and select the default wait time in the System menu. Enter the command vi/boot/grub2/grub. as shown in cfg, modify the value of timeout. The default value is 5, indicating that the system menu waiting time is 5 seconds.
