Step-by-step explanation:

Editing GRUB 2 Configuration:

To edit the GRUB 2 configuration on a Linux system, you can follow these steps:

1. Open a terminal window.
2. Enter the command sudo nano /etc/default/grub to edit the main GRUB 2 configuration file using nano text editor. You may be prompted for your password to gain administrative privileges.
3. Make the necessary changes to the file. For example, you can change the default operating system to boot, boot time delay, and boot parameters.
4. Once you're done, save the changes in nano by pressing Ctrl + O, then exit nano by pressing Ctrl + X.
5. To apply the changes, run sudo update-grub. This will generate a new grub.file.

Important note: Incorrect changes to the GRUB configuration can render your system unbootable. Make sure to double-check your edits and understand the implications of the changes you're making.
