Can't install Windows 8 - Partition problems

Hi all,

Ive recently installed a SSD (Samsung 830) into my iMac 2011. It already had a 1 TB HDD in it but I want to install Mountain Lion and Windows 8 on the SSD.

Installing Mountain Lion was a piece of cake but now im getting problems installing the bootcamp partition with Windows 8. See below

diskutil list:

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *1.0 TB disk0

1: EFI 209.7 MB disk0s1

2: Apple_HFS Untitled 999.9 GB disk0s2

/dev/disk1

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *256.1 GB disk1

1: EFI 209.7 MB disk1s1

2: Apple_HFS Macintosh SSD 255.2 GB disk1s2

3: Apple_Boot Recovery HD 650.0 MB disk1s4

/dev/disk2

#: TYPE NAME SIZE IDENTIFIER

0: FDisk_partition_scheme *16.1 GB disk2

1: DOS_FAT_32 WININSTALL 16.1 GB disk2s1

Ive tried to creating the bootcamp partition with the DISK UTILITY and the Bootcamp assistant, but neither of these methods work. Is it because of the 1TB HDD thats causing these problems or is it something else?

Regards,

Nick
