# 编辑grub.cfg，在BEGIN /etc/grub.d/30_os-prober段加入Win7的menuentry

vi /boot/grub2/grub.cfg

\### BEGIN /etc/grub.d/30_os-prober ###menuentry ‘Windows 7 (loader) (on /dev/sda1)’ —class windows —class os $menuentry_id_{    insmod part_msdos    insmod ntfs    set root=‘hd0,msdos1’    chainloader +1}\### END /etc/grub.d/30_os-prober ###
