How to install Pure OS as standalone

[Catacombs]

A Bit of advice would save me a lot of trial and error. Put Pure OS onto a DVD in a bootable format, as if I was installing from DVD onto hard drive. I create Stand Alone Qubes select install. I have Lenovo X230 with 16 GB RAM and a 500 GB drive. Settings. Memory I take to mean how much RAM. About 4096 seems right. The second I take to represent how much hard drive for this Qube. Next page again says memory and it’s seeming to suggest 200 mb? This is about memory and processor. I dunno what it wants. And I don’t see how to start install. Or which options will let me easily start it after install.

Any pointers here?

Thanks for advice.

Like I notice that a Fedora VM has a memory of 2048. Seems low. During install I guess it did not see my 16 GB RAM and set a minimal number in case my RAM was 4 GB. So I should probably modify Fedora Template as well? Debian Template? Not sure about Whonix. I have to look.
