The system enters an eternal loop, with the Ubuntu logo repeatedly appearing on the screen.
You're unable to access the login screen or desktop environment.

To troubleshoot the issue, let's try the following steps:

Step 1: Boot from a Live USB

Boot from the Live USB.
Open the terminal and run the following command:

sudo efibootmgr -v

If the boot order is not set to the correct device, run the following command to change it:

If the disk is still showing errors, run the following command to repair the disk:
