For example, I have Macbook Pro Retina, iMac, and Mac Pro. As it turns out, not all OSX are the same. After 10 hours, I finally have resolved this. I was stuck with this challenge last night as well. (Not EFI) This time when you see the partitions it will be select-able as the installation disk.ĭuring installation Windows rebooted 2 times and I use Alt-Option button just to be sure that proper disk was booted. At this point reboot with the Alt-Option button and select the Windows DVD.

Then I go to Disk Utility and manually divide Mac OS partition in two parts to add space (not formatted) for windows installation.Īfter 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. I removed Bootcamp partition with Bootcamp utility - this reverts partition table to GUID. Now when Win 8 installer have EFI boot mode, we actually don't need Bootcamp utility at all. Bootcamp utility creates hybrid-MBR table and this prevents Windows 8 to be installed. I also was looking for solution to this issue and find it by understand the roots of problem. Also quick format works too - will save you 2 hours on a 1TB disk. I managed to make it work by buying a USB SuperDrive and booting from the Windows disk (not EFI). This solution doesn't seem to work when booting from the bootcamp created USB. Press refresh and you should be able to select the partition.Select partition 4 (assuming 4 is your bootcamp partition)įormat fs=NTFS label='Windows 8' (I didn’t use QUICK) Select disk 0 (assuming 0 is the disk where you created the bootcamp partition) Press Shift+ F10 to open a command prompt window.Start the install and go to the partition selection screen.I formatted it on NTFS and after that it allowed me to select the partition and installed successfully there. 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 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.
