Linux Installation Checklist
Every Linux distribution differs slightly in the interface used to install the operating system on your desktop, the order of the information it requests, and the tools it uses to simplify the installation process. Regardless of the distribution, however, you must follow these four major steps to install Linux:
If you want to keep your existing operating system, resize the disk partition by using a partitioning tool or get a second hard drive.
Burn DVDs or format flash drives for your distribution and boot the PC from the DVD or flash drive.
Go through the graphical installation steps.
Configure other hardware when the system first boots.
