Today I compile the linux kernel 4.0.0 in LinuxMint!When I update grub

The content of /etc/default/grub is following:
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
It's pretty self-explanatory:
`GRUB_HIDDEN_TIMEOUT'
Wait this many seconds before displaying the menu. If <ESC> is
pressed during that time, display the menu and wait for input
according to `GRUB_TIMEOUT'. If a hotkey associated with a menu
entry is pressed, boot the associated menu entry immediately. If
the timeout expires before either of these happens, display the
menu for the number of seconds specified in `GRUB_TIMEOUT' before
booting the default entry.
If you set `GRUB_HIDDEN_TIMEOUT', you should also set
`GRUB_TIMEOUT=0' so that the menu is not displayed at all unless
<ESC> is pressed.
This option is unset by default, and is deprecated in favour of
the less confusing `GRUB_TIMEOUT_STYLE=countdown' or
`GRUB_TIMEOUT_STYLE=hidden'.
`GRUB_HIDDEN_TIMEOUT_QUIET'
In conjunction with `GRUB_HIDDEN_TIMEOUT', set this to `true' to
suppress the verbose countdown while waiting for a key to be
pressed before displaying the menu.
This option is unset by default, and is deprecated in favour of
the less confusing `GRUB_TIMEOUT_STYLE=countdown'.
