Windows 10 on Mac Pro 4,1->5,1

[h9826790]

I'm using my 980Ti and my GT120 both in the machine at the same time. The GT120 is deactivated in Win10, and no displays are connected to it. That means I won't get a boot screen either. I think the trick with using GT120 at boot to get boot screen would work, but as soon as you would go into OS X, it would be seen as two displays, and afaik there's no way to disable a display in OS X.

Another thing is that the "resolution manager" in win10 still sees the GT120 card as an external display, and then you'll have to choose "only show desktop on display 1" to make it work.

I don't get the boot screen, but I still leave the card in there for formatting purposes and stuff, and I don't want to keep taking out the card since I format fairly often...
Hope this helps

This is what you need to disable a monitor in OSX.

I tried. It works.

Yes, that helps and is a detailed explanation; thank you for providing it. When you first setup Windows (or purchased the 980 Ti) did you have both cards installed, or did you have to disable the GT120 in device manager in advance before putting the 980 Ti in?

I had both installed, and disabled the GT120 as soon as possible. Had to be done a few times because Win10 kept installing new drivers for it..

will disconnect the Internet help?

Just thinking may need Internet conenction to download and install the new driver.

If we disconnect the Internet right after the initial boot, it may help to gain us some time to disable the GT120.

Of course, if it's the build in driver cause the problem, then nothing we can do about it.

 

[ifraaank]

I tried that, but when I connect to the internet again, it still installs the driver even if I take the card completely out. Same happens when card is disabled, so you'll have to let it install all the drivers it want, THEN disable the card.

hi all,
I have tried everything I can find on installing windows 10 onto my 4,1>5,1 Mac, and I just can't manage to get past the part where I choose the partition to install on in the windows installed, it just says windows cannot be installed into this disk.
I'm losing my mind here, and worse everywhere I look I'm seeing people who have successfully done it! I mean, I can't even get windows 7 onto it! After j create the installer in bootcamp, the Mac reboots, then says there is no bootable device! I just don't get it...
Please would someone explain to me how they did it on a computer like mine...by the way, I'm running a 4,1>5,1 Mac Pro, stock 5770, El Capitan.
Thanks heaps,
S.

How you connect your target drive? Native SATA II port?

How you connect your target drive? Native SATA II port?

I think so....the sata II port is the normal hard drive bays in the tower right? If so, then yes, it's in there, 3 of the bays have normal hdd drive and the last one (disk0 in DU), is a 120g Samsung 850 Evo.
[doublepost=1480154672][/doublepost]I don't know why but bay 1 through 4, doesn't read that way in DU....bay 4 shows up as disk0 etc.
[doublepost=1480154908][/doublepost]I wonder, does the fact that I'm using a USB, (by altering the plist file of BCA), to boot off of and try install make any difference?
Before right now I didn't have any DVDs, now that I've got some, should I be doing it off of a disk (DVD), instead?

Did you format your target partition to NTFS?

 

[Simenzie]

Did you format your target partition to NTFS?

I formatted it to FAT(ms-did), in disc utility, then formatted it AGAIN from inside the windows installer
[doublepost=1480158776][/doublepost]I meant FAT (ms-dos)

 

[chriz_r]

..."format your target partition to NTFS"

This.

 

[Simenzie]

This.

Ok so how do I do that in disk utility?

Last week I bought several XP941, when I checked no 3, to my surprise it booted from Windows 10.

This flashSSD was take from a laptop.
No need for Bootcamp, just stick in the blade...and it works. (not that I'm using Windows )

What Mac do you have? A Mac Pro 4,1 updated to 5,1?

 

[carpsafari]

Yup, 4.1 to 5.1//3.46Ghz/48Gb/GTX980/

Damn I'm so envious! But seriously anyone else got any ideas for me? Cause I really need windows to flash a gtx680 4gb I got!! I feel like I'm losing my mind....I'm gonna try again now by burning the ISO to a DVD....cause I know the ISO is good I've installed it onto 4 different virtual machines with no issue...

If you only need to flash your card, I think there is a DOS version.

Anyway, use a Disc and Bootcamp should be the easiest way to install Windows.

What do you mean DOS version? How would I do that?
As for the Windows situation I'm gonna try with a CD tonight I'll let you guys know how it went...thanks for your help!

If you don't know what is DOS, don't worry about it, try the DVD first.

I did it! I used a cd, then I formatted the partition from command prompt in the installer and it worked! Thanks heaps for all your help!
[doublepost=1480187599][/doublepost]Now does anyone here have any idea where I could get an EVGA GTX 680 Classified EFI rom to flash my new card??

 

[paul.zhu]

That did the trick! I was then able to install the GeForce drivers, my bet is that the intel chipset drivers weren't installed when boot camp tried to install graphics drivers.. Odd sequence if you ask me..

But afterwards I installed the 980 ti graphics card and removed the GT120 and blank screen, nothing.. I then thought of using remote desktop to see if there was anything wrong, and windows couldn't start the 980 ti.. So I installed the geforce drivers again and bingo.. after a reboot it worked..

And now I have a working 980 ti graphics card in both Windows and OS X. But, not simultaneously with the GT120. Only OS X can handle both graphics cards at the same time. So I'm not going to through out the old card.

I've only used like a week to figure out this problem! Geez! Now on to the unrecognised broadcom 802.11AC + Bluetooth!

Thanks a lot guys! Your help really did the trick!

Hi Mejenborg,

I just got a GT120 in order to get boot screen and am facing the same issue when using boot camp with windows 10. I have exactly the same Mac Pro, 2009 4.1->5.1, with GT120 and Gigabyte AMD R9 280x. Both nvidia driver from bootcamp and Windows Update can cause reboot. Therefore I can only stop Windows Update automatic to install driver for GT120 for now, and it is recognized as Microsoft Basic display adapter. The driver for R9 280x is working fine.

I am wondering if the trick is still working for you. If I try and can't work, will have to reinstall windows again, which is so painful. The nvidia experience mentioned before, is the same as GeForce Experience?

cheers.

 

[chris.pielkenrood]

Also Some issues here. I can Install Windows 10 without bootcamp on Mac 5.1 (FW updated from 4.1). No issues there. Also i installed the bootcamp drivers only with removing the nvidia folder from the bootcamp installation folder. Everything works. I thema installed GeForce Experience after recommendation from here but during install of new FW for my GT 120 the Mac boots up and does not want to boot the Windows installation. I need to go back in safe mode and delete the display drivers. Then it will boot back up. Any suggestions About the next step? Thanks

 

[Charmandrigo]

I got it working by deleting the Nvidia driver inside the bootcamp folder, as the installer then skips the driver. I then installed Nvidia Experience, and it works flawlessly.

Thanks for reply, you're right. It's pretty much a Driver problem that neither Apple or Nvidia has bothered to fix
(after all the gt120 also has some fails on Macos High Sierra, like: Black screen on broadcasting software or web browsers freezing on image savings, as well as VMware freezing)
The best solution also, specially for not lose the apple boot manager (since the alt key checks if a certified gpu is installed) replacing the Gt120 with the ATI 5770 (from the Mac Pro 5.1) or the ATI 4870 (from the Mac Pro 4.1)

To resume things up. The Mac Pro Gt120 card sucks in many ways

Hello. I've installed Windows 10 on my Mac Pro 4,1->5,1. But when I try to install the BootCamp drivers, the Mac just shuts down in the middle of it. No error message, no nothing. No shut-down has ever occurred in OS X...

Specs:
2.66 Quad Xeon
NVIDIA GT120
16GB ram
stock HDD

Anyone else tried this?
Thank you.

Sadly this took me 4 days to figure out.
I have the same model system as yours.
Uninstall NVIDIA drivers! It seems the NVIDIA drivers included in Bootcamp 6.1 (for me) was the reason for the crash. Failure to uninstall equals a boot loop that will take you to Automatic Repair and it will never fix the issue.
You can uninstall in Safe mode I hope that helps!
