I install Debian 8 to my laptop, but there is no GRUB menu to enter Debian. How can i do that?

I disabled UEFI mode to install Debian, i think i did everything right. However, i couldn't see any option like Debian on booting screen. I have installed Linux Mint. There is no problem with that, but i want to use Debian also for some time. Any idea?

Answer to the question

I did some research and found that in the file "/etc/default/grub", there are options that you can set that will hide the grub boot menu. Here is a look at the grub file under "/etc/default/"

# 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_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=""

# 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"

 Open the file using nano or your preferred text editor and add a "#" to line that reads, GRUB_HIDDEN_TIMEOUT_QUIET=true, or either change the value to false. Then type in a terminal #sudo update-grub. This should give you the GRUB boot menu at startup.
