Linux Installation
Different methods of installing Linux
Virtualization and dual-boot setups
There are three main methods to install Linux
Live CD/USB installation, Network installation,
and Dual-boot installation alongside another
operating system. Each method has its own
advantages and is suitable for different
situations.
Virtualization allows running multiple operating
systems concurrently on a single physical
machine, providing flexibility and isolation.
Dual-boot setup enables choosing between two
operating systems on startup, ideal for
maintaining separate work and personal
environments.
