UPDATE: Apparently the GeForce 1050 Ti 4GB doesn't allow you to see the screen during boot which doesn't allow you to input key commands for recovery mode or boot select. The computer was booting from the last OS that was ran but still didn't explain why my drives were not being recognized. So what fixed the issue was just putting the old GFX card back in and setting my default OS to OS X.



I have a mid 2010 mac pro tower. I used bootcamp to add windows 7. I have done this many times on my iMac 2010 but this is my first time doing it on this Mac Pro. Once windows was installed to a new hard drive i purchased, I tried booting to OSX but I cant. The computer boots with no time to press any key commands and there is NO chime. I took out the drive with windows on it but the computer still tries to boot windows. I have tried holding option or CMD+R and even Ctl Option P+R. I am using a Bluetooth mac keyboard but I have it plugged in via usb. Is there any solution to get my OSX to boot back up?







Intel Xeon X5650 2.67GHz
32GB RAM
GeForce 1050 Ti 4GB
Windows 7 Home Premium

A pram reset should typically take you back to OS X (your keystroke above is incorrect) as should physically removing your windows drive.

You can use easyuefi to see which volume has boot priority in windows and then set it differently if you'd like or set one time boots to different OSs. Windows sometimes sets its self as boot priority one during install which could explain your problem.

I tried to download the free trial for easyuefi but it said my version of windows isn't compatible. Windows 7 home premium 32bit.

I opened up the msconfig.exe and went to the boot tab and it only shows windows 7 C drive current OS and Default OS. This is worrying me that I might have deleted my mac osx but when i take out the drive with window on it leaving my MAC drive in, it doesnt boot up windows. Maybe the mac drive isnt being recognized?

Hi!

Do you have OSX High Sierra with APFS installation? Windows can not "see" this file-system. Pull the GeForce 1050 Ti and get a GPU with Bootscreen. Hold "alt" key down and go to bootscreen. Then hold down "Ctrl" key down at the same time as you click on your OSX disk. Then OSX is blessed.

Best regards

I am not sure about the APFS. I am not that knowledgeable. Do you mean take out the GeForce and put another graphics card in the machine?

When I turn the machine on it stays quiet for about 10 seconds and the. It just boots directly to the last OS that was running. I removed the internal storage and the windows OS drive leaving my OS X ssd and I get a message saying “No bootable device found”

I guess if your win 7 isn't an efi based install then easyuefi can't help. If you pull your windows drive and perform a pram reset (cmd+opt+p+r) it should boot to any OS X volume present. If it doesn't then I think you'll need to put a graphics card in that will allow you to check what's going on during boot up.

WHOA WHOA WHOA! Don't go tearing your machine apart just yet!
OS X ssd and I get a message saying “No bootable device found”
Did you possibly damage the SSD with OSX (or MacOS) on it while removing it from the drive? Can you access internet recovery for your Mac Pro at all? Do any keyboard short cuts work? Try ALL of them!

This problem was happening before I removed anything. The only thing I did after troubleshooting for an hour was power down. Unplug the machine. Then removed the windows hard drive. I will put the old gfx card back in. That card allowed me to see the screen during boot.

I still have the original card. I’ll try that out.

The original card worked. I was able to boot in to option and choose my Mac HD. Thank you!!

I know its too late for this time, but next time you install Windows remove your other drives first. Much worse things can happen, and so removing the other drives first can prevent big problems. Thankfully its quite easy in a cMP, just open the side and pull the other drive sleds out an inch.

Off topic but if you want a PURE Win experience . . . install Windows on it's own dedicated HDD

Remove all current Apple drives & external USB sticks .. . insert a Win ONLY HDD and either the Win 7, 8, 8,1 or 10 install DVD .. . boot holding down the OPTION key. . . .at ( assuming you have at least one Apple boot screen GPU) ( flashed 5770 ? ) .. . select the Win install DVD . . . hit ENTER . . .. . you'll get a black screen with a spinning backslash for up to 3 minutes .. but your Win install disk WILL run if you select it.
Install WIN. . then you'll have something to play with.

The OPTION key at startup is vital.

BootCamp, ultimately is a compromise.

That actually make thing complicated.

After burn the disc. Leave that in the super drive.

Shut down the Mac.

Pull ALL hard drives out and ONLY leave / insert the Windows hard drive.

Then holding C to boot.

This will boot to the Windows installation disc without the need of boot screen. Even with a non flashed Pascal GPU, the graphic card will still be initialised by the Windows installer.

Then just need to follow the on screen instruction to finish the installation.
