Dont give up!
Let me walk through my menu to show you exactly what to do, I will edit this post in a few minutes!
So start fresh, delete your volumes and follow the numbers.
1) Sign into Dreamcompute Dashboard.
2) Select "Instances" Tab.
3)Click "Launch Instance"
4)Select the dropdown menu under "Instance Boot Source"
Select "Boot from Image (creates a new volume)"
5)Fill in the "Instance Name"
6)Click on the "Access and Security" Tab, select a keypair.
8) Now the Dashboard should say something like "scheduling the creation of xzy123" and the box should be green around the text.
Now you should be able to see your instance being scheduled and initialized, after it is running, click on the drop down menu on the right of your instance and select "Add floating IP"
I think we might live on opposite sides of the planet so if it doesn't work let me know, I will check back often to make sure you can get up and running. You can do it!
