i'm running mac pro 5,1 velocity duo x2. card has 2 ssd on it, although 1 has bootable os--to more specific, 10.12.6 , windows 10 on separate partitions. before morning, able boot either os 0 issues, , run windows 10 on parallels in 10.12.6.
morning, removed pcie cards routine cleaning. after returned way before, realized couldn't access windows in parallels, had stupidly signed free trial latest, expensive upgrade (and outside trial period). wanting go windows, decided boot directly there, greeted black screen, , black screen only. remained way @ least 20 minutes. 10.12.6, on other hand, worked had before.
normally, when had booted windows off velocity duo x2, bios screen briefly appear, before windows' normal start-up kick gear. never saw sign of screen today.
i've spent of day changing pci slots of cards, switching drives on velocity duo x2, booting off drives hard drive bays instead (windows works when drive placed in drive bay), reinstalling drivers, etc. i'm still left black screen when try boot windows.
friend of mine thinks may have zapped card , messed bios, other i'm not sure happened. said, card -does- work in 10.12.6, and--after paying it--i able access windows through parallels while drive on velocity duo x2. want believe there's simple i've overlooked can done fix things.
ideas on how proceed? i've emailed tech support apricorn, i'm hoping there's easier way make work way did @ 9:00am before started fiasco.
so, belay last. apparently above created boot order issue.
yesterday morning removed dvd drive , not replaced it, thought there grinding sound originating it. before turning in night, put ssds on velocity duo x2 , tried parallels running again, couldn't access windows, , received message optical drive not found.
shutdown , put dvd drive in, and, say, voila--windows booted, should have.
in short, idiot.
all.
