Hello again, well after much troubleshooting I have discovered that there seems to be a problem with d630 10.12 bootpack Extra folder. I was able to install fresh using the upgrade route after updating Enoch on El Cap.
Problem was that after accomplishing this it was right back to no startup menu to use boot flags and since I can’t use flags no startup. So I got the idea to try the El Cap Extra since I was able to boot up Sierra startup with El Cap install usb.
With the El Cap Extra folder on Sierra usb I get the startup menu. To be sure I then replaced it with the Sierra boot pack extra folder and no go.
Weird huh?
Edit: Needless to say, it will not let me install Sierra because smbios says it’s MBP 5,1 but when I use the one from 10.12 Extra making it 7,1 it hangs.
