Dual boot with Clover bootloader

[theorange]

Hey guys, so, I'm trying to get a dual boot running on my 2TB drive, 1.5TB for windows and 500GB for mac os. I've loaded a usb with the mavericks installer as well as clover efi. Put it into my new build, and opened up disk util to split up the partitions, making sure that it was indexed with a GUID partition table.

I'm now about to install windows 8 on it, and when choosing the 1.5tb partition to install on, I get the following flags:
 

Windows cannot be installed on this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only installed on GPT disks.

Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS.

Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure the disk's controller is enabled in the computer's BIOS menu.

 

The one about NTFS was easily solved by just formatting it in the installer.

The one about booting to the disk not supported, I thought I must've left some drives on RAID mode or something, but I checked, and they are all set to AHCI, I guess I'll have to deal with that one later.

As for the one concerning partition tables, I have no idea, because I created a GPT in disk utility, so I don't know what's going on there.

Anyone else had this problem before? Any fixes?

When you use Disk Utility to create a FAT32 partition for Windows, it automatically assumes you will be installing Windows in legacy MBR/Bootcamp mode ---> creates a hybrid MBR (see article by Rod Smith on GPT) ---> hence the error you see with the Windows installer if you try to install UEFI Windows.

 

You can avoid the problem in the first place by formatting the Windows partition as HFS+ in Disk Utility (or just leave empty disk space), then use the Windows installer to format the partition back to NTFS.

 

To fix your current problem, you need to use GDisk to write a protective mbr on your hard drive ---> restores full GPT status.

 

Download GDisk

GDisk Man page

Use option "b" to backup your current partition tables to a file, then...

option "x" to access the experts menu, then

option "n" ---> create new protective MBR, then option "w" to write changes to your disk and exit.

 

 

Good Luck!

 

Edit:  Once you fix the partition tables with GDisk, you'll find that you won't have the "boot support" error anymore - I trust Gdisk to do the job more than DU .

Oh, right, I remember running into that problem before when I tried bootcamp on a genuine mac. I haven't added anything to the partitions yet, so I'll just totally reformat it. Thanks for the help!

 

Do you happen to know the problem with the boot support? All my drives are in AHCI mode.
