I like Hare's exegnu version. however, I guess I can install Debian Live with uefi support. then load Trinity on top of it! I will have to check if I installed Windows via uefi. NetRunner is, I'm pretty sure, using uefi. however, you imply that there will be problems if Windows is not under uefi. presumably I would have to boot it from the 'BIOS' instead of via grub-efi. if so, not pretty but tolerable. I don't have time right now for magic surgical operations. f. > > On 1 January 2017 at 06:22, Felmon Davis <davisf@...> wrote: > >> On Sat, 31 Dec 2016, Gene Heskett wrote: >> >> On Saturday 31 December 2016 12:56:59 Felmon Davis wrote: >>> >>> greets! >>>> >>>> I want to install Trinity on a multiboot uefi system.
