Added install guides

Now there is guides to help the user install for ubuntu, arch and windows.
Notice that im a linux user and my pc is weak, so i could not test it on another operational system. Also the guide is in portuguese (all of them), please use your browser built-in translator or any of them to read if u dont understands portuguese
I could test it on another linux distro, but i would have to go through all the install steps. Also i cannot try installing windows because it normally wipe out another OS installed on the same disc (i know that it just replaces the bootloader) and using a VM was not possible due to the amount of RAM and the processor that i have.
