I want to hide GRUB2 boot menu in Ubuntu 23.04, but it can open from booting proccess as I want. I try to add GRUB_TIMEOUT = -1, but it can't hidden and still showing. My /etc/default/grub file as it :

# 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=hidden
GRUB_TIMEOUT=-1
GRUB_RECORDFAIL_TIMEOUT=$GRUB_TIMEOUT
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"

If I set it GRUB_TIMEOUT = 0, I can't open GRUB2 menu but it hidden as well. I try to hold Shift or Esc button but it can't GRUB2 menu. I want to make my Ubuntu like Fedora, it can hide GRUB2 boot menu but it can acces by holding Shift button. What should I do? Thanks for your help

Do not use 0 as then you never can get to grub menu. I like to use 3 so menu only appears just long enough for me to press a key to change boot. If install is UEFI, then you press escape key not shift key which was for old BIOS installs. Are you dual booting? Grub wants to show menu if dual booting.

@oldfred, I'm only single boot Ubuntu 23.04 in my computer. I think I can use 0 for full hide GRUB2 menu, but I want it can accesible to open with a key for open it. I can get it in Fedora, but not in Ubuntu

Do not know how your Fedora does that. But with Ubuntu and 0 time, you never get grub menu. And if then you need recovery boot, you cannot and then have to use a live installer and chroot into system to make even minor repairs.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
