Hi
First of all download putty (
http://the.earth.li/...t/x86/putty.exe) , its one of the most common ssh clients for windows.
Now start up putty (no installation is needed), in the new window write down the ipadress of your xbox in the host field and select ssh protocol (just under host).
Now click on the open button, you will get up something like "The server's host key is not cached in the registry" and some more text including your xbox´s "fingerprint", this is to protect you from "spoofing. Just klick OK or yes.
Now you will get a black window that say "login as:" type "root"
now it will say "sent username root" "root@someipadress´password"
type "xbox" and you are in.
After that i quess it´s just to follow the tutorial (check that you have internet access and then type "XBOXLinuxInstall")
I hope this helps...
