I'm trying to install Windows 8 with Bootcamp on my Macbook Pro. Sadly it won't let me get past the disk partition choice (even after formatting the Bootcamp-drive).

It says:

Windows can't be installed on this storage device. The chosen harddisk contains a MBR-partition-table. Windows can only be installed on GPT-harddisks on EFI-systems. freely translated

What is going wrong here?

did you try reformatting that disk to NTFS? Also, i wouldn't recommend running windows 8 on a macbook pro, there are no drivers that are compatible with it. Bootcamp drivers do NOT install when the OS is up and running. –  AlanTuring Oct 1 '12 at 1:07

I was having a similar problem, the first time I got the same MBR error, rebooted and started getting a generic error to check the install logs.

What fixed this for me was to format the partition using diskpart, opened a command prompt on the "select partition screen" and formatted the partition. I formatted it on NTFS and after that it allowed me to select the partition and installed successfully there.

Here my steps:

  1. Start the install and go to the partition selection screen
  2. Press Shift+F10 to open a command prompt window
  3. Execute the following commands:

    select disk 0                      (assuming 0 is the disk where you created the bootcamp partition)
    select partition 4                 (assuming 4 is your bootcamp partition)
    format fs=NTFS label="Windows 8"   (I didn’t use QUICK)
  4. Press refresh and you should be able to select the partition.

This solution doesn't seem to work when booting from the bootcamp created USB. I managed to make it work by buying a USB SuperDrive and booting from the Windows disk (not EFI). Worked like magic after that. Also quick format works too - will save you 2 hours on a 1TB disk.

Thanks a lot, this solution successfully solved a long and painful search for me. The only thing I had to do in addition to your steps was to reboot my Mac and restart the installation process. –  Florian Feldhaus Dec 30 '12 at 9:30
This didn't work for me, still won't let me select the partition –  marchinram Mar 12 '13 at 4:45
This didn't work for me either I'm afraid. I also tried formatting using the UI, which seems to just silently fail. Whatever I've tried so far the installer still thinks that the drive has a MBR partition table. –  andynormancx Mar 29 '13 at 12:25

I also was looking for solution to this issue and find it by understand the roots of problem. Bootcamp utility creates hybrid-MBR table and this prevents Windows 8 to be installed. Now when Win 8 installer have EFI boot mode, we actually don't need Bootcamp utility at all.

I removed Bootcamp partition with Bootcamp utility - this reverts partition table to GUID. Then I go to Disk Utility and manually divide Mac OS partition in two parts to add space (not formatted) for windows installation. After that, when I rebooted with Alt-Option button, I was able to choose EFI Boot option on inserted DVD disk and successfully install Windows by create appropriate partition on space that I prepare with Disk Utility. At this point reboot with the Alt-Option button and select the Windows DVD. (Not EFI) This time when you see the partitions it will be select-able as the installation disk. During installation Windows rebooted 2 times and I use Alt-Option button just to be sure that proper disk was booted.

This was exactly the problem I had - thanks very much. –  RB. Dec 13 '13 at 13:55
THANK YOU! After trying everything and everything, this was the solution that worked. Turns out Apple's Bootcamp is a load of crap. Just use Disk Utility to resize the drive and go. Thank you. –  balupton Sep 15 at 5:12

No it isn't. The problem didn't happen with non-final versions of Windows 8 and it is also not described at that page. –  Hedge Oct 1 '12 at 12:00
