i have read about as much as i could with opencore, and everything along those lines, but no one seems to be able to answer a simple question.

i have a flashed up 5,1 with mojave on a nvme, that boots just fine with opencore and the bootpicker by itself. i also have windows 10 installed from dvd on a sata ssd in bay 1. that boots just fine (by itself, no nvme in machine). if i have both drives installed, opencore doesn't load at all (black screen for hours), or if it does it goes straight to the mac boot picker (only works about 1 out of 10 times). when it does boot into os x, when i want to boot into the M$ drive, startup disk doesn't see bay 1 ssd. bootchamp is too old and doesn't see anything at all to boot.
what are some of my options so i can bounce between either drive when i need them? bootchamp alternatives or anything along those lines? maybe some special IT code for opencore to see the legacy ssd?

they are talking about a different opencore, not the same one that i installed. the one i have is a clover icon with the efi folder that you put into the mounted efi drive with the bless efi script. so i have no idea on what they are talking about and what to put where and how to chain load squat

Seems you need to read some more about OpenCore. There are some packages and the automatic package generator known as oclp.

But all share the same OpenCore and same configuration method.

So that works for you and legacy Windows.

i followed the instructions, made the bootable usb stick, stuck it in my mac pro, now i have nothing, black screen, nothing else, 5 min later with still a black screen, i hear the mac chime again. and it repeats itself. no picker on the usb, no opencore on the nvme, i am not starting from scratch if everything is lost.

tried smc reset, tried pram reset, tried blindly pressing cmd + R and nothing
