I have this in my grub setting

# 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
GRUB_TIMEOUT_STYLE=menu
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=7e7b14ea-9a18-42f9-ba6c-d62581e038a9"
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"

but the time out during boot time is 30 sec.

What is wrong with this setting?

Note: I DID use the following command to update-grub

sudo update-grub

I also run this command in case it helps but no success.

Sudo update-grub2

I am using Ubuntu 20.04

Update 1

grep -i timeout /boot/grub/grub.cfg
  set timeout=30
  if [ x$feature_timeout_style = xy ] ; then
    set timeout_style=menu
    set timeout=10
  # Fallback normal timeout code in case the timeout_style feature is
    set timeout=10

so the cfg is correct but the timeout is still 30 sec. What this line is doing? I think this line return false and hence the timeout is 30 sec.

if [ x$feature_timeout_style = xy ] ; then
