If you break your Ubuntu system and try a lot of ways to fix it, you end up giving up and taking a simple approach: reinstall Ubuntu.

As far as I know, there is no system recovery partition like Windows in Ubuntu. So the question arises: how do I reinstall Ubuntu? Let me show you how to reinstall Ubuntu. We've been in a situation where reinstalling Linux seems to be better than finding the problem and fixing it. Troubleshooting Linux can teach you a lot, but you don't always spend more time fixing broken systems.

Warning! Disk partitioning is always a dangerous task. I strongly recommend that you back up your data on an external disk.

How to reinstall Ubuntu Linux

Here are the steps for reinstalling Ubuntu.

Step 1: create a live USB

First, download Ubuntu from the website. You can download any version of Ubuntu you need.

Download Ubuntu

Once you have obtained the ISO image, you can create a live USB. If the Ubuntu system is still available, you can create it using the boot disk creation tool provided with Ubuntu.

If you can't use your Ubuntu, you can use another system. You can refer to this article to learn how to create a live USB for Ubuntu in Windows.

Step 2: reinstall Ubuntu

Once you have the live USB for Ubuntu, plug it into the USB port. Restart the system. At startup, press keys such as F2, F10, F12 to enter the BIOS settings and make sure "Boot from Removable Devices/USB" is set. Save and exit BIOS. This will launch into live USB.

After entering live USB, choose to install Ubuntu. You will see common options such as selecting language and keyboard layout. You can also choose to download updates and so on.

This is an important step. You should see a "installation type" page. What you see on the screen depends largely on how Ubuntu handles the disk partitions on the system and the operating system installed.

Read the option and its details carefully in this step. Note the description of each option. The options on the screen may look different in different systems.

Here, it found that Ubuntu 18.04.2 and Windows were installed on my system, and it gave me some options.

The first option is to erase Ubuntu 18.04.2 and reinstall it. It told me that it would delete my personal data, but it didn't say delete all operating systems (that is, Windows).

If you are lucky or in single boot mode, you may see an option to "reinstall Ubuntu". This option retains existing data and even attempts to retain installed software. If you see this option, use it.

Note for dual boot system:

If you are dual-boot Ubuntu and Windows, and during reinstallation, your Ubuntu system does not see Windows, you must select the "Something else" option and install Ubuntu from there. I have explained the process of installing Linux under dual boot in this article.

For me, there was no option to reinstall and retain the data, so I chose "erase Ubuntu and reinstall". This option reinstalls Ubuntu even in Windows's dual boot mode.

I recommend using separate partitions for / and / home just to reinstall. In this way, the data in the / home partition can be secured even if Linux is reinstalled. I have demonstrated in this video:

Once you have chosen to reinstall Ubuntu, all that is left is to click next. Select your location and create a user account.
