Edit Grub Config:

there are two possible situations here
(1)If you have only chrome OS installed you again have two easy options
{a}(temporary)quickly press e when you see grub edit and press f10 to boot.
{b}open terminal(Ctrl+Alt+T) first enter shell then type sudo edit-grub-config
Save by Ctrl+o (Press enter to confirm)
Exit by Ctrl+x

(2)If you are dual-triple booting then edit the grub config you have created in linux
Be sure to run sudo update-grub to save your changes

Usage:
(1)Add options: Add "options=option1,option2,..." (without spaces). For example: booting with "options=enable_updates,advanced_als" will activate both options.
(2) Add kernel parameters: place enforce_hyperthreading=1 or console= after "cros_debug" and before "options=...." if any
