Is there a way to hide the Grub2 menu so that it does not show by default and boots off the pre-selected OS immediately unless another key, like F8 in Windows, is pressed after BIOS to intercept the boot?
gksudo gedit /etc/default/grub Set GRUB_HIDDEN_TIMEOUT to the number of seconds you want to have to press shift before it starts booting and take the hash
# mark out of in front of it. Save the file and the changes will be applied next time you boot.
Yes of course you can.The easy way is the following:
Install startupmanager package by opening a terminal window and typing
sudo apt-get install startupmanager
Then run startupmanager and set timeout in seconds to 0 .Press the close button and once the "performing post-configuration tasks" window dissappears you are done !
