MacPro 1,1 does not see Mac hdd with windows hdd installed

[pgilmore7]

Hi everyone this is my first post. I have a MacPro 1,1 with dual quad core processors, 32GB or ram, 1,1 to 2,1 update, you know the usual stuff. It’s running OSX 11.6 on a 120GB SSD. I have a hard drive out of a PC with windows 10 on it and I installed it on my Mac. It started up and ran windows fine but now it won’t see the Mac HDD. Is there something I’m screwing up? Any help would be greatly appreciated.

Yes, that's correct. You have no access from Windows to your Mac HDD, without installing some third-party tools, such as MacDrive (from Mediafour.com), or Paragon makes "HFS+ for Windows". Either of those allows you to read and write to your HFS+ format HDD.
If you need to reboot to OS X when you are booted to Windows, just restart, holding the Option key. Choose your OS X boot drive from that option-boot screen.

Sorry, the discription of my issue wasn’t clear enough. That’s my issue, when I reboot with the option key pressed it only shows the windows disk.

Try an NVRAM reset, followed by an Option-boot.
If that does not help - if you slide the Windows boot drive out, does the OS X drive then appear in Option-boot?
Which slot are you using for the Windows drive? If slot 1, try moving to OS X boot in slot 1, and the Windows boot drive in slot 2 (or some other slot)

All you normally need to do is a PRAM(NVRAM) Reset. Holding the option key isn’t required. PRAM reset always boots to the 1 OS X drive it finds.

Thank you for taking the time to help. I pulled the drives, reinstalled, and did the PRAM reset. It now works like it should. I’ve used Parallels on my iMac and boot camp on my MacBook Pro, on this one I just pulled the drive from my PC and stuck it in and it came up. I guess I can’t complain if this is my only issue. I might need to clone this drive though, it’s slow reminds me of my old PC.

Get the free 14 day trial of BootRunner3 and you won’t need to do PRAM reset anymore. You can boot back effortlessly using their boot selector.

Readup briefly on how to use it, but you won’t have to configure it. The defaults work fine.

Thanks for the heads up, I’ll check it out. Sweet ride in your profile pic btw. I work for Ford, one of the reasons I have to have Windows, that and Steam.
