[Linux Small white] dual system add Windows boot and modify boot order

First, install the NTFS-3G plug-in

When CentOS7 is installed on a Windows system, it is found that the boot entry does not have the WINDOWS7 option, because Linux does not recognize NTFS-formatted partitions by default, and the NTFS-3G plugin is installed.

The installation method is as follows:

# yum Install ntfs-3g

Second, add the Windows boot entry

1. Type the command: (log in as root)

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

2. Open the View Grub2 profile to view:

# vi/boot/grub2/grub.cfg

3. Find the # # #BEGIN/etc/grub.d/30_os-prober # # #, see if there are windows7 menuentry, if not, add later:

Menuentry ' Windows 7 ' {

Insmod NTFS

Set root= (hd0,2)

Chainloader+1

}

Note: hd0 means hard disk, 2 means sda2 (C drive), my win7 is mounted on C drive.

4. Save restart

Third, modify the boot sequence

1. Set the default startup item (here, Windows 7 will match the name of the Menuentry set in the previous step)

# grub2-set-default ' Windows 7 '

2. Verify Default Items

# grub2-editenv List

Output at this time:

Saved_entry=windows 7
