How can I directly access the Ubuntu system from the grub menu?

To access the Ubuntu system directly, you can follow these steps:

1. First, start the computer and enter the GRUB boot menu. On most computers, press and hold the Shift key after pressing the power button until the GRUB menu appears.
2. Use the directional keys on the GRUB menu to select the Ubuntu system entry you want to enter. It typically appears as “Ubuntu” or “Ubuntu with Linux x.x.x”.
3. After selecting the Ubuntu system option, press the Enter key to enter the Ubuntu system. GRUB will begin loading Ubuntu and start the operating system.

If your computer is not displaying the GRUB menu or is booting directly into the Windows operating system, you may need to modify the GRUB settings in Ubuntu to show the menu. You can use the following command in Ubuntu to open the terminal and edit the GRUB configuration file:

sudo nano /etc/default/grub

In the open file, locate and comment out (add a # before the line) the following line:

# GRUB_HIDDEN_TIMEOUT=0

Then save the file and exit the editor. Finally, run the following command in the terminal to apply the changes:

sudo update-grub

After restarting the computer, you should be able to see the GRUB menu and directly enter the Ubuntu system.
