Steve, first of all, well done for persevering with it, and extra credit for trying something new.
I'm puzzled as to what you are putting on this thing. You've got a 16GB SSD but only 70MB of space left? For comparison, I have a standard XP Pro install VM fully patched and running from an 8GB drive. It has Chrome, Wireshark, SnoopyPro, CProbox, Samsung phone utilities, EPC and WIS installed and I still have over 1GB free. Had you deleted the partitions you created, or were you still working with separate OS and data partitions?
Although it is good practice to use separate partitions, for the size of drive you are talking about you can't afford to waste space, and I would use a single partition to avoid either constricting the OS or depriving myself of data space.
If you are ever coming this way, let me know in advance and I'll show you how to image the drive to another machine so you can easily restore it to a known configuration.
