Replaced SSD - Boot/HDD problem

First off thank you for any help.

Previous system had Windows 7 Enterprise N x64 installed on an OCZ Agility 2 SSD 40gig. I also have a 2.2TB HDD that I use as storage. The PC started not recognizing the HDD at boot up, and the SSD was also appearing much more full than it actually was. I couldn't see it in My Computer OR in Disk Management. After explaining the problem to Pops, he said he thought it was the SSD giving me the issue. So, I have replaced it with an OCZ Vertex 3 60gig, and reinstalled Windows 7 Ultimate x64.

There are two problems, the first being the big issue which is I can see the HDD in Disk Management, but I can't see it in My Computer to view the files.

Secondly, now I have a dual boot screen where as the first option is the correct operating system, but the second option is the old Windows 7 (which when selected tells me it's trying to see the old SDD, which isn't available)

I'd like to remove this dual boot screen and be able to see my HDD (which has all of my important files on it)

Thanks again.

UPDATE - Had to assign a Drive Letter (DERP)

Still need to fix the dual boot situmacation.

Start > Run msconfig

Startup tab

Unclick the other OS

Done.
