The GRUB timeout is 8 seconds. Can this be turned down to 2 or 3 seconds? What is the best way to do this?

Try

sudo nano /etc/default/grub

change the GRUB_TIMEOUT value to 2 or 3

save

sudo update-grub

Not sure if I have a complete answer as I have a few more questions.

First - Permissions: you would normally need sudo to edit grub.cfg. If I'm editing from the commandline, I like nano, which is installed by default, so I would use

$ sudo nano /boot/grub/grub.cfg

If you haven't used nano before, once you're done editing use Ctl-O (the letter) to save and then Ctl-X to exit (the Ctl-O is optional, Ctl-X will prompt if there were changes)

Second - Grub: Editing /boot/grub/grub.cfg is probably not the way to go. Grub2 uses the file /etc/default/grub to get all its options and then generates grub.cfg for you. This is important, because grub.cfg gets updated when there's a kernel update or other things that might affect grub. So if you want your changes to stick you need to edit /etc/default/grub.

$ sudo nano /etc/default/grub
$ sudo update-grub2

REMEMBER TO MAKE A BACKUP BEFORE YOU CHANGE SYSTEM FILES :D

Third - 10s wait: I'm not actually sure that grub is your villain here, but hopefully the above will help you figure out if it is. Alternatively, can you elaborate a little more. Are you in the grub menu when you "select Ubuntu to boot?" what happens once you've selected it? Or are you referring to the grub picking a default OS - in that case /etc/default/grub will help.

    Editing grub.cfg with Grub2 is a bad idea period. And of coursE Grub is the "villain" responsible for the 10 sec default timeout on multiple-boot systems!!

A GUI method is to install StartUpManager:

$ sudo apt-get install startupmanager

You can set the Grub2 timeout using this utility.

You might try installing a GUI interface startup manager called "Grub Customizer".

Doesn't look like it's in the repos though. But you can find it here at Launchpad: Grub Customizer

Once installed, boot into Ubuntu, start Grub Customizer and configure it for 0 countdown. Then when you boot there should be no wait.

for this you have to change the value of GRUB_TIMEOUT value to 2 or 3 .

1 - go to super mode

su -

followed by typing your root password

2- now open the GRUB.cfg file either in vi editor or Gedit (Gedit is easy (GUI))

vi /boot/grub2/grub.cfg

or

gedit /boot/grub/grub.cfg

3 - then find GRUB_TIMEOUT and change it's value 2 or 3

4 - save the changes

5 - if find any difficulty then watch my video on youtube . click here to watch the video

    As we are talking about Ubuntu by default you can't log into your root account – and you shouldn't change that. I would recommend using sudoedit /boot/grub/grub.cfg. If you want to use gedit simply add a line VISUAL=gedit to your ~/.bashrc. Last but not least, mind the notes on grub2 from above.

The timeout behaviour is different on systems with EFI and BIOS. EFI grub sticks on 30s. There is bug report on it, 1918736. Suggested fix is to set GRUB_RECORDFAIL_TIMEOUT in /etc/default/grub to change the delay from 30 seconds.
