New computer os

just got a new computer built. it has never had an OS on it. How can i put kali linux on this computer without having an OS to start with? Thank you 

yep just load it up

Borrow a computer to create a live USB stick from downloaded ISO, or burn the ISO to a CD/DVD. Alternatively, a lot of Linux distrobutions will sell optical discs with their respsective systems on it at a low cost ($5-$10; it does cost money to produce and ship, so you aren't really paying for the OS, but you do support it).

You can buy a Kali CD here:

yup this is how you would do it.

Borrow a friends computer and burn whatever ISO you want to a disc, or buy a pre made disc. I would recommend just burning your own ISO, its easier and you dont pay too much.
