I have CSM enabled; I installed Windows 7 then on the MBR. subsequently I installed NetRunner. the computer boots by default to NR. when I go to 'BIOS' or whatever it's now called, there are two options for NR, one is marked 'uefi os'. the option for Windows is not so marked.

I guess exegnu is now restricted to Devuan? I'll check. not absolutely married to it but it's been my standard. I installed NR only because I was in a bit of a rush in that moment and didn't want to fool around with getting up the wifi drivers - exegnu live doesn't see the wifi whereas NR does 'out of the box'. once up I just decided to go with the install and see how NR worked.
