Installing KUbuntu Linux
KUbuntu is a version of the free Linux operating system that includes the intuitive Plasma desktop and KDE applications. The Plasma desktop is similar to the Windows desktop and Windows users find it fairly easy to learn.
Bootable USB Drive
Boot and Install
Boot the computer from the USB stick and start Kubuntu to install. This may involve going into the BIOS settings on the computer and enabling boot from USB, or entering the Boot Manager menu (F12 key while booting on Dell laptops).
Installation then proceeds. If you choose to install Kubuntu on the entire disk, it will wipe out whatever was on the disk previously. If you have a Windows operating system you want to keep, the installer can resize the Windows portion and install Kubuntu in a dual boot configuration. This is advanced stuff, so back up your Windows system before you go this route!
