I am trying to install Windows 7 on my Mac pro, I have tried everything it seems. I have a perfectly good Windows 7 DVD which boots on other devices, yet it doesn't on mine. First off it started with spitting out the DVD (which I can understand ;) ), so I thought its my superdrive. I went and bought a new drive today, except this is a SATA drive and tried to boot from there. It load the DVD fast and easy within OSX, but when I reboot and try to boot from the disk it hops to a flashing Apple logo and a deny logo (circle with a diagonal line thru it).
What am I doing wrong? The DVD is legal, its not an illegal copy (however, I tried that as well.. and didn't work either). I googled it a bit but cannot find any similar problem.
With flashing logo's, I mean it flashes every second between these two logos:
Edit 1
I have now also tried it using Windows 8, downloaded from Microsoft.
Edit 2
I have now also tried it using an Windows XP Disk. Same problem, flashing icons.
Edit 3
I have now also tried:
- Removing all drives and installing OSX 10.6 on one of the 1TB drives. Using bootcamp and installing. Same problem
- Reformatted my 750GB Drive and added MBR support. Formatted as Fat drive. Same problem.
- Removing all drives and trying to boot from disk. Nothing happens, just a white screen.
- Reset the PRAM so many times that I guess the computer almost tells me to give it a brake.
- Tried booting with only C hold down. Same problem.
Nothing seems to help.
Also, I just found this page: http://support.Apple.com/KB/HT2674 According to that page, the problem is:
Circle with Slash - could not load boot.efi, or some other issue
and
Metallic Apple - found boot.efi.

Edit 4
I tried all evening to restore the firmware, but it just refuses. The sleep light flashes a few times, the tone comes, then the normal sound boot sound comes and OSX boot like it should. I am getting crazy here.
Edit 5
Tested as well with both 10.5 and 10.6 retail disks, they load perfectly. (Maybe due to that they have GUID formatted?)

1Run the BootCamp Assistant, follow the instructions and insert the DVD when it says to. At what point does it fail? – Brian – 2012-01-25T22:42:41.383
If you don't want to use BootCamp see: http://derekhat.com/install-vista-on-a-macbook-without-bootcamp/
– Brian – 2012-01-25T22:46:34.873Yes, that is exactly what I have done. I also tried booting holding ALT and selecting the disk, booting holding C (Come to a screen which informs me no bootable devices are found). I have now also tried it with Windows 8, downloaded directly from Microsoft. – Paul Peelen – 2012-01-25T23:10:11.913
@Brian I found that site yesterday and tried that as well. Same problem. – Paul Peelen – 2012-01-25T23:11:27.933

Is it Windows 7 x64 or 32 ? Are you using a USB mouse and keyboard? – harrymc – 2012-01-28T11:38:08.877
Its Windows 7 x64. I am using a USB keyboard corrected to the screen which is connected to the Mac Pro. The mouse is bleutooth, but I have also tried it with a plugged in logitech mouse. – Paul Peelen – 2012-01-28T11:45:54.060
