LOL yeah it was pretty stupid of me

. Had a load of files strewn across all my partitions which I didn't want to lose so I wanted to duel boot to make sure the 7127 would go without it messing up and losing any files but seeing as it was working fine I thought I might as well get rid of 7100 now I know the new build runs smoothly. I've placed any of my important files in the 2nd 'data' HD now anyway.
You're right looks like I might as well done it the easy way in the end ha ha.
Well I'll see what happens anyway.. Thanks again!
