How to Create Startup Disk in Ubuntu Linux

This post describes steps you can take to create a startup disk in Ubuntu Linux.

Ubuntu Linux lets you create a bootable disk that you can use to restore your computer when there’s a problem. For you to create a startup disk, the flash drive must have at least 2GB of storage capacity on it.

Any data on the USB flash drive will be erased or lost when you create a startup disk. So, make sure you’re not using a critical flash drive and that you don’t have any useful data on it.

In order to create the disk, you must download an ISO image of the version of Ubuntu Linux you want to install or use to repair your local computer.

Below is how to use Startup Disk Creator tool to create startup disk in Ubuntu Linux.

As described above, users can use Startup Disk Creator to create startup disk that can be used to install or repair your computer.

It’s assumed that you have downloaded an Ubuntu ISO image.

To create a startup disk from an Ubuntu ISO image.

Open Startup Disk Creator via the Activities search bar and launch the app.

If the ISO image is in your Download folder and there is just one ISO image, Startup Disk Creator will have selected it, otherwise select the correct ISO image you want to install.

If your computer has just one USB flash drive, Startup Disk Creator will have selected it, otherwise select the correct drive that the USB flash drive is plugged into.

Click Make Startup Disk.

Click Yes to confirm. The process should take ten minutes or less.

When the “Installation Complete” window opens click Quit.

When you’re done, grab the USB flash drive and boot the computer you want to install Ubuntu on from the drive. If the computer boots properly, Ubuntu Linux should be installed on the computer.

That should do it!
