dos bootable os

Solution
Most Linux operating systems can boot a machine from a Live CD or a USB flash drive.

Download one of your choice - Mint is a good one for starters - and use Rufus or similar to make a bootable flash drive or ImgBurn to make a bootable CD.

They can both run a computer without impacting on the installed system.
