When I pressed install Odyssey, I knew it would take a while so I left the computer to downloading. After a couple of hours I checked it, and it had runout of space on the C drive 125gb SSD - this contains all the OS files so not much free space! I want too install Odyssey on my D drive 1TB HHD - plenty of space, How do I select the D drive for the install? As you are not given a choice?
