How do you get Windows 8.1 to do a clean install on a Haswell based rMBP?
OS X Mavericks (10.9), 2.6Ghz 16GB 1TB
Option-Command-P-R on boot to reset PRAM and then I can install Win 8 fine just by following the standard bootcamp install process (can I have my night back Apple?)
Awesome - that worrked for me (although I lost a night as well). After resetting, just needed to booth from EFI manually using the Option key
Thanks ianday!
Your solution is the only thing that worked for me (and I've tried everything else suggested in the forums) - and yes, I can confirm that the "Almost Ready" screen seems to take forever and that the Bootcamp installer does launch after that long wait.
This worked for me (15" MacBook Pro Retina 2014), thank you very much.
Here an addition some might find useful:
Once you are in windows, you'll find that all Apple-device specific drivers are missing. Most obvious, you have no WLAN-device.
Navigate to your USB installation drive from within windows, and find the BOOTCAMP folder. Inside, you see a setup.exe - start it. It will install all missing drivers for you.

Hello,
I have a Macbook Pro 2014 model running OSX 10.9.2 but when I try the instructions I continue to get the following error when Windows begins it install:
Your PC ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you. If you'd like to know more, you can search online later for this error: 0xc000021a
I've tried the instructions twice and I keep getting this error. I tried searching but couldn't find anyone who was getting this error message with a Macbook Pro. Any insights would be greatly appreciated!
Hello,
concerning the problem of the lone use of the Nvidia GPU under windows instead of the intelligent switching between the Iris Pro an the GT750m under WIndows, do you know what happens when Parallels or VMWare is used? Does this matter still occur then?
Greetings

I got this a bunch of times and here's what I did to get it to work:
(advice only applicable to late 2013 macbook pros)
1) You must first reset your PRAM as per http://support.apple.com/kb/ph14222
2) After resetting your PRAM hold down OPTION and select the EFI option so that it will install windows in the true EFI mode / if you use the other option it will try to install in BIOS emulation mode which won't work.
3) Install Windows 8 - not 8.1 not 8.1 update - as 8.1/update caused me to get the above error. Once you have Windows 8 installed you then a) install all windows updates b) can then use the Windows Store to upgrade to Windows 8.1 update (it will go straight to 8.1 update).
4) Use a Windows 8 or Windows 8 Pro ISO - When I tried a VL (volume license ISO I got the above error as well).
I hope that helps - I've done it on a couple of Macs in the last week or two and it works fine every time as long as I follow those four steps...

In BootCamp windows it will always use the Nvidia GPU (there is no Intel GPU in windows.
In Parallels / VMWare MacOS will a) use the Intel GPU when a single screen is running b) use the Nvidia GPU when you have more than one screen running - as far as Windows is concerned it's using a Parallels or VMWare virtual GPU in this case...
Try out (http://gfx.io/) it will help you see what is going on with swtiching GPUs.
Thank you so much for the response but even after resesting the PRAM, I still get the error. I purchased my license key from the Microsoft store and I verified it is 8.1 Pro for a clean install (not an update). Even when I try EFI mode after reseting the PRAM I get the error:

Any other suggestions are welcome! 😟
I have a disk from Microsoft, so I decide to start from Jarvil's step 8 and skipped step 10. So far so good. Wish I had read his solution earlier. Thank you so much, jarvil!!
I have a 2014 MB Pro - resetting the p-ram is what worked for me...I was not able to format the partition and move to the next step otherwise. Installing windows 8 from a boot drive... which i got from the windows 8 installation on my 2011 MB Air

Solution (steps I did in addition and probably unnecessary)
Delete Boot Camp partition in Boot Camp Assistant
Verifid 1 partition using Disk Utility (Macintosh HD)
Restart and PRAM
Boot straight to OS X Recovery
Open Disk Utility
Repair Disk permissions twice (didn't appear to do any further permissions repairs since my previous failed install)
Repaired Disk - Macintosh HD
Repaired DIsk - SSD
Restarted to OSX
Ran Boot Camp assistant, not bothering to re-create the install USB
Auto restarted to Windows 8.1 installer
Completed install without error
I now have a working Windows 8.1 install with EFI on my 15" Haswell retina Macbook Pro
This worked for me as well. I allowed Boot Camp Assistant to create the partition and then during the Windows install, I selected the new partition (0:4) and formatted it.
15" MBP retina Mid 2014 and Windows 8.1 Pro with update
thank you,
this is the only method successfully helped me, im using rMBP (mid 2014) on OS X Yosemite.
Thank you so much! Worked a treat 🙂
