Aurora R5, trying to create boot from M2 SSD

Hi

Have now landed up unable to boot my PC.

  I've fitted an M2 ssd and was trying to get this to be the boot disk.  I could see it on disk manager.  I cloned my hard disk to it using Macrium and could see the files on it.  So I booted but was still from HD.  So tried various ways to get it to boot but no luck.  

I then decided to try a clean install of windows and from usb drive and it will not install to any of the partions as it says I already have windows.

In very simple terms can anyone tell me how to clean this mess up and get it to boot from the ssd.  (I intend to reformat the hd to use just for data).

Thanks Eddie
