You need to create a bootable live disk to clone your disk. You can not copy a partition that is mounted. If you do not have internet access, use gparted. Otherwise, it might be better to use your operating systems live installer, such as Manjaro. We can download gparted and still have things like a web browser incase we get stuck. We will be using the Manjaro live disk for this guide.
- Download Manjaro.
- Insert USB disk.
