Hello! I am very new to linux and ubuntu. And im following a tutorial to install it on my Acer Aspire Switch 10. So far it has worked. But now i need to do something with 'apt-get' but i don't have internet. And the tutorial doesn't state how to do it.
I have searched this forum but a lot of things don't seem to work.

For information:
I'm following this tutorial: https://gist.github.com/franga2000/2154d09f864894b8fe84
And im now trying to install grub on the pc.
The pc has no ports other than a usb port. (Power and other stuff ofcourse)

Can anybody explain to me how to do this? In a easy to for a noob to understand message?
Thanks in advance!
