good luck with the bug report, I was always confused, when on way on github... complicated overview etc.
So: it s a bug, when rEFind is greyed out? But then it either came back or is still there, as my fruitless attempts in the past (same problem, when dual boot partitioning) caused me to try Virtualisation instead of dual boot in the 1st place and where I had discussions with Eric about. He told me with GhostBSD 25.01.x and on, it shd be possible w/out probs. That s why I tried on my desktop again - successful - but no chance on my Toshiba Portege..still don t know, what s the reason for the one successful, the other not. same configuration, but either rEFind greyed out, or IF visible, same errors as lazylew...
