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 infer NR is uefi while Windows is not.

in my case Windows is a "bootable option" but I think you mean 
"bootable from grub"?

ok. this is pretty clear. to fix it so grub-efi works I'll have to 
re-install Windows 7.

this I do not know - it was one motive for my caution.

well, Lisi suggested I could use some standard live Debian disk. 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. 
(I used it for a spell some yrs ago.)
