Most modern Linux distributions make it fairly easy to switch from Windows. Wubi lets you install Ubuntu in a dual-boot configuration from Windows. For most other distros, such as Linux Mint or Debian, it’s mostly a matter of grabbing the correct 32-bit or 64-bit ISO, burning it to a CD or USB stick, and rebooting your PC.
Windows 8 and Ubuntu dual-bootTo begin with, make sure you install Linux in a dual-boot configuration. That way, if you’re struck by switchers remorse, or you suddenly remember that you need to use an app that’s only available in Windows, you can simply reboot.
Depending on your hardware setup, installing and running Linux for the first time can be a bit tricky as well. A modern distro like Ubuntu 14.04 supports most hardware under the sun, but you may have trouble with older hardware or extreme outliers.
Fortunately, if you are having issues with a device after installing Linux, you can normally find very good support online.
