Problem:
When installing Centos7 on a computer Windows 7 system, the Windows 7 boot menu cannot be found after installation.
Reason:
Because CentOS 7 has adopted the new grub2 system, you need to enter the /boot/grub2 directory and use vi to edit the grub.cfg file.
(Recommended tutorial: centos usage tutorial)
Solution 1:
Modify the Grub2 boot of Centos 7 and add the Windows startup item
1. sudo vi /boot/grub2/grub.cfg
2. Find
BEGIN /etc/grub.d/30_os-proberat the back Added:
menuentry "Windows 7 (loader) (on /dev/sda1)" { insmod ntfs set root=(hd0,1) #由于我的windows安装在硬盘的C盘,故(hd0,1) chainloader +1 }
Solution 2:
The system automatically detects whether there are other systems
grub2-mkconfig -o /boot/grub2/grub.cfg
Linux can only recognize Ext3/4, fat32 format, if Windows is an NTFS format disk partition, Grub2 will not recognize it. Recommended related video tutorials:
