How To Repair Linux Mint With Live Usb

In this blog post, we will guide you through the process of repairing your Linux Mint operating system using a Live USB. This could be necessary if your system is behaving irregularly, or to fix an issue that prevents your system from booting.

Step 1: Creating a Live USB

Firstly, we need a Live USB with Linux Mint. You can download the latest Linux Mint ISO from the Official Linux Mint Website. Once downloaded, you can use tools like UNetbootin or Rufus to create a bootable USB drive.

Step 2: Booting from the Live USB

After creating the Live USB, insert it into the system that requires repair. Restart your computer and hit the key that brings up your boot menu (typically F12, F10, or DEL). Choose to boot from the USB device.

Step 3: Starting the Repair Process

Once the Linux Mint desktop environment is loaded from the Live USB, open up the terminal. Your file system should be checked and repaired using the fsck command.

First, find out the partition name where Linux Mint is installed using the command lsblk or sudo fdisk -l.

Next, unmount the partition with the command ‘sudo umount /dev/sdXY‘, where X is the drive letter and Y is the partition number.

Now, you can use the fsck tool to repair the file system. Note that this operation should be done with caution as it can lead to data loss in case of any errors.

The command to perform the check and fix operation is:

        sudo fsck -fy /dev/sdXY

In this command, -f option stands for force check even if the system thinks it is clean, and -y automatically answers yes to all the prompts.

Step 4: Reboot System

Once the fsck command process is completed, you can reboot your system. Remove the USB drive and let the system boot from the hard drive.

If the repair process was successful, your Linux Mint system should now boot and operate normally. If you still encounter problems, you might want to consider reinstalling the OS or seeking expert assistance.

It’s always a good practice to regularly backup your data to avoid losing it during such operations.
