CentOS 7 Installation Restore Windows boot entry

Install CENTOS7 on the computer WINDOWS10 system and cannot find the Windows7 boot menu after installation.

Reason: Because CentOS 7 has a new GRUB2 system, you need to use VI to edit the grub.cfg file after entering the/BOOT/GRUB2 directory.

Workaround One: Modify the GRUB2 boot of CentOS 7 to add the Windows startup entry

1 1.sudo vi/boot/grub2/grub.cfg2 2. Find the # # # begin/etc/grub.d/30_os-prober # # #3    add 4    menuentry "Windows Ten (load ER) (on/dev/sda1) "{5      insmod ntfs6      set root= (hd0,1) #由于我的windows安装在硬盘的C盘, therefore (hd0,1) 7      chainloader +18    }

Solution Two: System automatically detects if there are other systems

Linux can only recognize the EXT3/4,FAT32 format, and if Windows is an NTFS-formatted disk partition, GRUB2 will not be recognized.
