grub> find/boot/grub/stage1 find/grub/stage1 Find Stage1 #命令行下输入下列三条命令, there's always a way to return to the correct grub location
Grub> Find/grub/stage1
Find/grub/stage1
(hd1,1)
Grub>root (hd0,0) #第一条
Grub>setup (hd0) #第二条
Grub>quit executes these three commands in a #第三条 grub environment to return to the shell
