I solved this problem myself after more forum searching
For those who encounter the same problem ... I read this thread:
The steps I took:
- I booted from recovery mode (Hold 'Command' and 'R' while starting up)
- From the menu screen ... On the top bar I selected 'Utilities > Terminal'.
- This opened a terminal window.
- Then I typed: diskutil CoreStorage list
- And hit 'Return' ...
- This showed the main storage drive details.
- From there I found the UUID string ...
- Which is basically the long number displayed under the storage drive name.
- I selected and copied this ...
- Then I typed: diskutil CoreStorage delete
- Followed by the UUID string number ... And hit 'Return'.
- The system then erased the main drive (it left the recovery dive intact though).
- I then quit Terminal ... And went back into 'Disc Utilities'.
- Only to find all of the drives displayed individually and in red ...
- The 'Solid State Drive' and the 'Hard Disc Drive' were no longer displayed as one 'Fusion' unit.
- However ... Upon clicking on one of the drives ...
- The system recognised they were not unified ... And prompted me to fix this.
- I asked the Disk Utilities to 'Fix' ... And the system returned to its normal state.
- With the drives displayed as:
• Internal Drive
• Macintosh HD
I was then able to install the OS X on the 'Macintosh HD' partition.
