You guys go totally off topic in this thread.

I just have a few questions I didn't see while reading. I have a 5,1 with a HD 5870. It is on High Sierra and is my Emby Server. I managed to use a donor card to get the last boot rom. I can't seem to find a version of windows 10 that will fit on a DVD so that I can install it on a spare drive and do all of this since some of the software I am going to need is windows based.

1) Can this all be done in a windows 10 VM using VirtualBox?
2) If not, does anyone have a download to a Version of 10 (or 7) that fits on a DVD? I got blank DVDs and a Optical drive, and even a VM if I have to. Every link I chase wants me to already have windows set up, and some sites are saying to use a DVD and not a bootable USB.
3) If not, can I just make a liveDVD/CD of linux (like mint or Ubuntu) and just do all of this there?
4) Since I only have one pair of 6 pin power cables, which GPU should be powered and hooked up? In other words, do I use the stock 5870 but have the other card installed, do I boot with the 7950 powered up into my VM/live Dvd/7 environment?

I am just a little confused. My goal is to eventually upgrade my Mac Pro Emby Server to Mojave, maybe Catalina. I just want to be able to do safe browsing as I multitask this machine and it is always on.

The current windows 10 iso file downloadable from Microsoft will fit fine on any double layer DVD. Boot Camp assistant asks for it and will install a full Windows 10 on a properly formatted drive (FAT or NTFS). Flashing isn't going to work with virtual widows.
