MacbookPro 9.1 OCLP Bootcamp method not working

[jlnabais]

Hello all,

I followed https://dortania.github.io/OpenCore-Legacy-Patcher/WINDOWS.html for my Macbook Pro 9.1 but when running the bootcamp installer (even on windows 7 compatibility mode) I get black screen, if I go to safe mode and remove graphics drivers it works again, but obviously I would like it to work as it did in the past. I am trying to install windows 10. I tried other methods like intall using https://sourceforge.net/projects/windows-install/ but I end up always at the same point.

Does anyone have a definite guide that works with Intel and Nvidia drivers installed? I saw some threads that I should also download a more recent bootcamp installer and replace some files on windows32 drivers folder but I never get to the point of finishing the setup before my screen goes black and when I restart I get blue screen always unless I go to safe mode and delete drivers.


Note: I have done the install with internet off so windows update does not mess with it. I reset NVRAM several times also.

I personally wouldn’t recommend trying to do a UEFI installation of Windows on a MacBook Pro of that vintage. I have a 2012 MacBook Pro 9,1 and did an uneventful legacy Windows 10 installation after I had OCLP up and running MacOS Ventura. Do you have your OCLP MacOS running, and if so, which MacOS? And do your have a MacBook Pro 5,1, or is your model 9,1 - like mine?

I used the following tutorial for legacy Windows installation -LINK.

A few years ago, I attempted a UEFI Windows 10 installation on my 2012, and it was bootable, but neither audio nor Thunderbolt could work. So I haven't ever bothered with it again. Boot Camp Assistant automatically downloads the necessary Windows 10 drivers for my MBP 2012 (9,1). But Windows is bootable without them. But they're necessary for the sound card, trackpad, and my Nvidia GeForce 650M. When running Boot Camp Windows, your Intel GPU is ignored. No drivers are downloaded by the Boot Camp Assistant.

Sorry is MacBook Pro 9.1.
I have OCLP running latest macOS Seqoia ATM, does that guide work with this OS Version?

OK, then you have my MBP, or something very similar. Yes, Boot Camp Assistant should function just as it does in that guide for you. Especially if you haven't created an extra EFI partition for Windows or anything like that. If you did, because of your previous Windows install attempts, I would mount that partition and empty it. And not worry about trying to recover the 200 MB.

Once again, you have a Mac that's old enough that Windows should be installed in legacy BIOS mode. And Boot Camp Assistant knows that.

I've checked comments associated with that guide, from about 4-6 months ago. I've seen successes with Sequoia.

Although it wasn't important for me (for some reason), it's often essential that your internal DVD drive works. Is that the case? Actually, I think the guide talks about MacBook Pros (old ones) that lack DVD drives. But if yours should have one, and it now doesn't, that can make it difficult.

Provided you have a Win10 ISO, a blank DVD, and a USB drive, it should go well. BootCamp Assistant will do the "magic" that makes Windows thinks it sees an MBR partition on a UEFI disk, and the correct drivers for Windows 10 should automatically be put on the USB. If I remember correctly, it's BootCamp 6.1 drivers that are for Windows 10. I had no problems. Just followed the guide to the letter.

The USB also installs Apple Software Update for Windows, and there's about 3 updates you definitely want to install.

Inhave a disk on the DVD drive now but I have the original on an USB externam enclosure though. I need 2 ssds. One Windows one Mac os X

You may run into issues. When you reboot and hold down option and attempt to install Windows, if you see the word Windows under your DVD, all is good. Boot from It. Or for that matter, if you are lucky enough to see the word Windows underneath the icon for your USB drive, you can boot from that and install Windows successfully. But if you only see EFI under the icon, you won't be successful. I am sorry to say that if you put your internal drive in an external enclosure, you may not be able to do a legacy install from that disc. I had my DVD outside of my MBP for awhile, and it made Boot Camp installation BRUTAL. But in an OCLP environment, with my USB drive I actually had the choice between USB Windows (legacy) and EFI boot. I hope that you are lucky enough to see the same. Fingers crossed. If you don't see the word Windows anywhere underneath a boot choice, not good. The word Windows means you are about to do a legacy BIOS install.

I have never attempted Boot Camp with a separate hard drive. Just followed the guide you saw. You definitely want to erase it as MBR partition scheme, MS-DOS FAT or ExFAT. Either is OK

I decided to hook up my MBP to an external Blu Ray drive and start it up with both my Win 10 DVD and my USB drive inserted. At least with OCLP Ventura, the boot picker screen is good news - I can do a Windows 10 legacy install using either my DVD or USB drive. Hopefully, since your machine should be similar, you'll be as fortunate. You DON'T want EFI Boot in either case. See photo.
