  1. I appreciate this guide, but it doesn’t seem to address the fact that people will have more than just one drive to utilize for an Ubuntu installation. For example, you mention the OS and its various partitions being put onto “/dev/sda” but what about all the rest of the data? For instance, I’ve got only 20GB on my current “sda” disk, and then I’ve got my 1TB “sdb” disk for all the rest of my data and files (music, pictures, videos, etc.). Could you recommend a method to install with two disks?
