I purchased an Aurora R10 Ryzen edition off ebay with no graphics card and no hard drive as an upgrade from my R1 which I was using as a software dev box. So far its been a disaster and I hate this thing.

First off, I have an msi 960 graphics card. I don't do gaming much so I don't really need anything bigger, just something that will handle my 48" monitor. Plugging this in I got no display. I heard this was because Dell requires a Dell branded graphics card. So I got an R7 250 off ebay. From there I was able to at least get display.

Then I plugged in my Samsung EVO SSD running Windows 10. It does recognize it in the BIOS but I can't seem to boot from it. I'm assuming it has to do with Secure boot. I disabled that and wanted to do a Legacy boot, but for the life of me I can't figure out how to enable Legacy boot. UEFI is the only option.

With the amount of information on my drive, reformatting or reinstalling windows isn't exactly feasible, as I have SQL Server, Visual Studio Ultimate, multiple other dev tools, etc running and I'm working easily 12 hours a day including weekends so I don't have much time. Any ideas how I can get this to work?
