Ubuntu – need ‘Ubuntu’ and ‘Advanced option for Ubuntu’ and ‘memory test’ on grub

bootdual-bootgrub2startup

I'm new to the Ubuntu world.
But I have googled this issue and did not find any good answers.
On startup of my machine, I see grub (I am planning to install multiple OSs) and I see that there are four options:

  1. 'Ubuntu'
  2. 'Advanced option for Ubuntu'
  3. 'memory test'
  4. 'memory test ( with serial console ) '

Can someone please explain why I need all of these options and how I can hide the 'memory test' and the 'Advanced option for Ubuntu' ?

Best Answer

Why you have these options:
Ubuntu is hopefully the only thing you will have to boot into, but the others will become more useful if somethings breaks. For example, if the newest kernel has issues with your machine, then you can try booting with the old one under advanced options. Memtest is useful for looking for memory errors and stress-testing your RAM.

How to hide the other options:
I recommend using Grub Customizer to edit your grub options and instead of deleting the options having a menu folder labeled "other stuff" or something like that in case you need these in the future.

You can install Grub Customizer with these commands:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get update
sudo apt-get install grub-customizer
