一.可启动的内核条目
/boot/grub/grub.cfg

二.编辑 /etc/default/grub 设置默认启动的内核条目

    # If you change this file, run 'update-grub' afterwards to update
    # /boot/grub/grub.cfg.
    # For full documentation of the options in this file, see:
    #   info -f grub -n 'Simple configuration'

    GRUB_DEFAULT=0                    //修改这里选择默认启动的内核版本
    GRUB_TIMEOUT_STYLE=hidden
    GRUB_TIMEOUT=0
    GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
    GRUB_CMDLINE_LINUX=""

    # Uncomment to enable BadRAM filtering, modify to suit your needs
    # This works with Linux (no patch required) and with any kernel that obtains
    # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
    #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

    # Uncomment to disable graphical terminal (grub-pc only)
    #GRUB_TERMINAL=console

    # The resolution used on graphical terminal
    # note that you can use only modes which your graphic card supports via VBE
    # you can see them in real GRUB with the command `vbeinfo'
    #GRUB_GFXMODE=640x480

    # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
    #GRUB_DISABLE_LINUX_UUID=true

    # Uncomment to disable generation of recovery mode menu entries
    #GRUB_DISABLE_RECOVERY="true"

    # Uncomment to get a beep at grub start
    #GRUB_INIT_TUNE="480 440 1"

三.修改完成后使用命令：
sudo update-grub
该命令会自动更新/boot/grub/grub.cfg

四.总结
