CUSTOMIZING GRUB LOAD TIME

By default Linux grub load time is 5 seconds,

this may be a disadvantage to users dual-booting(more than one operating system on one machine) machines

basically changing load out time is impossible but not by use of terminal command

NAUTILUS

step.1

open terminal as root

or enter sudo su command

run command nautilus

step 2.

after running the command

opens file manager, open other locations

open the kali GNU/linux drive

step3.

Open etc folder

etc

step4.

open default folder, default

step5.

go to the file grub

step6.

open the file with mousepad

step7.

navigate through up to GRUB_TIMEOUT

for 50 seconds enter 50 after "="

step8.

this is the most essential step, missing out on this step may lead to grub rescue, or the system may return to default load out time

use command sudo update-grub

you can now restart you machine
