How do I install LEAF OS


The simplest way to install LEAFOS is to start the target PCs/Laptops using a bootable USB stick that runs LEAF OS with the following 2 options:

Installation option #1 (live boot LEAF OS using USB flash memory stick) 

Your device will boot LEAF OS from the connected USB flash drive. There will be no changes to the PC/laptop’s internal HDD.


Installation option #2 (flash LEAF OS into HDD to boot from) 

The contents of your device’s HDD will be wiped and flashed with LEAF OS. When you boot the device, LEAF OS will be directly booted from the internal HDD.

For larger installations, a PXE boot server can be set up to boot LEAF OS from a server on a network.
