PS THANKS SO MUCH
I know you might want to kill me but i have only windows 7 64 bit on disc (legit copy). So i have been pirating the other windows versions like windows 7 32bit and windows 8 64bit, nether the less they all gather the same result. The pirated windows comes in an ISO file and I opened it and i then burned to a dvd. Like i said before bootcamp runs smoothly and i have been following tutorials correctly. when bootcamp reboots my computer i hold down 'option' and then my drives come up and a disc called 'windows.' I select the disc and press enter and my computer tries to load the disc but comes to a black screen with a underscore _ that flashes 3 times then it disappears and the screen is still black. Thanks for your help on this forum, hopefully there is enough information there to help you figure out the problem.
I am glad you got it working.
I would recommend steering clear from ISOs that do not come directly from Microsoft. People have a tendency to modify them in some cases.
You can download pretty much about any version of Windows 7 directly from Microsoft hosting servers but if you got Windows 8 going and Windows 7 has failed many times, it may not be worth looking in to.
I am still unsure why you can't install it "normally" but the EFI Boot should be fine on a Mac Pro and actually boots somewhat faster than the "official" supported way.
Hey guys i have now successfully booted from the windows 8 EFI boot and i am running into one problem. Everything goes all good until i select custom install and i select my bootcamp drive and it wont let me for some partitioning errors created by bootcamp. Could someone please send me a fix
This is normal. Boot Camp Assistant makes the drive FAT32. You will need to select the BOOTCAMP partition and select Advanced, and Delete. You will the see it turn into free space of the same size. Ensure the free space is selected, and select Next and it will do the necessary partitioning for EFI for you.
thanks but i get these two errors:
1. Windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks
2. Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disks controller is enabled in the computer's BIOS menu.
That is odd. When you select EFI Boot, the EFI firmware on the Mac Pro should not be presenting the disk as an MBR disk, but rather a GPT disk.
Can you go into OS X and run the Boot Camp Assistant to "Remote Windows 7 or later" (or something like that) and it should remove the FAT partition it created, and hopefully a hybrid MBR if one exists. Then use Disk Utility to make some free space on your drive but do not partition it in Disk Utility. Just leave it as free space.
The try booting Windows 8 using EFI Boot and see if it sees the disk as type GPT.
black screen after boot camp restarts
My mac has a ssd and old mac harddrive in it, whitch means i took out my internal disc drive and using it as a external usb drive. i counldn't install windows until i put back the disc drive back into the macbook. Then i was able to use bootcamp to install windows 7.
hope this helps. may need to use another disc drive. hard part is you may need to take it out of an old computer and put it in your mac and let it hang so you can change disc. until the install is complete, reassemble every back together.

When i delete my bootcamp partition and check disk utility nothing comes up because the drive has been removed. When i go into windows nothing relating my drive comes up
I have been doing more research into this and apparently EFI boot is impossible on some models of mac and on some others it creates many driver issues. I wish i could just get this fixed as soon as possible. Some people say that the whole drive has to be a windows drive (not a partition) to be able to use windows on it.
You have in your signature it is a 2010 Mac Pro. They are virtually identical to the 2012 model, which is what I have, and it will EFI boot fine. There are driver issues with MacBook Pro models (my MacBook Pro with Retina display will not do it without blue screening) but the Mac Pro is in fact one that it works flawless (for me) on.
Can you post a screenshot of your Disk Utility?
I ALSO UPLOADED A VIDEO TO YOUTUBE OF ME GOING THROUGH THE WHOLE PROCESS HERE IS THE LINK: https://www.youtube.com/watch?v=3veNZ8a-8ZM
That is interesting. Typically booting EFI would bypass the CSM/BIOS/MBR presentation to Windows.
Is there any way that you can remove the drives except Drive 4 and attempt a reinstallation of Windows 7 using the standard method. I think it is safe to say that you have a non-standard disk layout. Not that is not fine, but it could perhaps interfere with the Windows installation. I would be curious to see what the Windows 7 installation looked like.
by drives i take it that you mean internal. If you look at my disk utility i use 2 drives for osx bootup 1 drive for backups and 1 drive for random stuff (bootcamp on this one). I personally dont think it would make a difference. Maybe i could try and boot windows 7 in EFI mode. I know some others are having this error aswell just wondering what is going on. Do you think this guide would work for me? JUST TRIED THIS AND IT DIDNT WORK: http://www.tech-recipes.com/rx/9839/how-to-manually-partition-boot-camp-your-mac-for-windows-7/

2.Hi all,
May be different but try same resolution I took, as my error says "windows cannot be installed on this disk. The selected disk is of the GPT partition style."
I'm a old IBM PC timer with over 17 years IT experience but just bought a new spanking Mac Pro ($5,600+). I am trying to install Windows Server 2008 R2 onto a 2nd internal HDD (Seagate 3TB).
I had this problem (same error message) for the past several hours and reading the Boot Camp Assistant documentation and several blogs did not help. However, those documentation gave a hint.
Number of partitions supported by OSX 10 matters (in my case, 4 max it seems). My first Mac HDD has 3 partitions. The 2nd HDD has an EFI and a BOOTCAMP partition - after running that program inside OSX and rebooted.
No matter what I do, Windows Installer results in the error on paragraph 1.
Resolution: Delete the EFI partition at disk partitioning stage during Windows installer process. Once deleted, the 2nd HDD should be one unallocated disk and can be partitioned as the 4th partition. Windows Installer then allows "Next" to be chosen and to proceed with Windows install.

I also used this and i got with all the errors but one, but the only problem is that this makes my hard drive only usable in windows
1. shift f10 (opens console)
2.diskpart
3. list disk
4. select disk 5
5. clean
6. continue with windows installation
this allows me to press next but then when windows is installing i get this
windows installation encountered an unexpected error. Verify that the installation sources are accessible and restart the installation
Error Code: 0XC0000005
Was this using the media that you got from a questionable source, or was it an actually pressed DVD from Microsoft?
The commands that you performed above wipe the disk drive and any other partitions you had one it.
it was from the pirate bay. it had a lot of comments saying it worked, just to check i will download from microsofts site.
To OP:
I have been following this thread with some interest but it seems to be going nowhere so far. If we go back to the very beginning, I tend to agree with the above quote and it's likely that your hardware arrangement somehow was in conflict with the Boot Camp installation. Reading the FAQ from Apple, you'd see there are lots of restrictions on what kind of drives can be used for Windows partition and installation, and I suspect that somehow your rather complex arrangement of drives could create some confusion for Boot Camp. If you could put the intended HDD with a clean install of OS X in bay 1 and remove other RAID drives and use the Boot Camp Assistant with the Windows 7 DVD, you may have gotten your Win 7 installation. This is no different from installing a GPU which had drivers/hardware conflict.
Given that you switched to EFI boot approach midway in the process, maybe this link could help you with this approach, and this is the guide I'll follow to reinstall Windows Server 2012 (the server version of Windows 8) when I get around it. Personally I'd avoid any non-Microsoft downloads just in case they might have been modified with potential harmful stuff.

thanks for your help. I'm trying to install windows onto a 500Gb hard disk (standard disk that most mac mini's use). Do you think if i remove all my drives except the 500Gb drive it will work or do you think i should do that with also a clean install of osx?. PS this drive has no OS on it, it is just used as storage
If I were in your current situation, I'd remove/disconnect all drives except the 500GB HDD and the internal DVD drive. Put the HDD in bay 1 and do a clean install of OS X, then start the Boot Camp process. This is the minimum hardware for a Boot Camp install. If you cannot do it successfully this way then there is something seriously wrong, although I really doubt it. Once you successfully install Windows on the HDD, you can move it anywhere, even to a bootable external enclosure, and it should still work.
If you have read the FAQ of Apple's Boot Camp link, you'd notice that there are many restrictions on Boot Camp installation, such as no RAID or external drives, no connection of more than 1 USB drive, etc. Keeping the minimum hardware is to make sure no violation of those restrictions. Hope this helps.
How do i install osx I only have Mountain Lion downloaded through the mac app store how do i install on on my drive? Usb boot or do i have to install it to a dvd
Making a bootable USB drive, as explained here, is the best way to quickly do a clean install on any drive. Just remember to remove it before starting the Boot Camp process.
Thanks very much for your help. I used this websites strategy: http://blog.thedeltaflyer.com/2013/01/dual-booting-windows-8-and-mountain-lion-natively-using-efi/. This strategy worked perfectly until i pressed next on the windows drive selection screen. I select the drive and I press delete and then i press next. It takes me to the windows installation screen. After 5 seconds i get this error message:
Windows detected that the EFI system partition was formatted as NTFS. Format the EFI system partition as FAT32, and restart installation.
I understand what that error message means but how do i fix it?
I had this issue with my 27'imac I had to plug in a different monitor into the mini display port and the windows install screen ran on that monitor Nd the main monitor remaind blank till windows rebooted at the end of the install.
So I don't think it's your disc / drive /DVD etc try having 2 monitors plugged in at the same time and see what happens.
thanks for you help. I will try that if the efi method i have been given fails, but i believe that the efi method will work. Thanks for your help
