after upgrading to 19.04 the Grub menu have become hidden. It still works and I can boot to both Windows 10 and Ubuntu by blindly finding the entry and pressing enter. I have tried to edit the
/etc/default/grub and running
sudo update-grub afterward but no change. Here is how it looks now:
# 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=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_TIMEOUT_STYLE=menu GRUB_HIDDEN_TIMEOUT_QUIET=false # 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"
I can't use either
Esc to make it visible too. After pressing either of these, Grub doesn't work anymore and I need to turn my laptop off and on in order to boot.
Edit: Not sure if it helps or not, but I just realized that if I go to the BIOS when I exit BIOS the grub menu shows up with no problem. The next time I boot, the grub menu is invisible again.
