How do I prevent my computer from dual-booting?

I hope this is the right section for this.

Here is the backstory:

I ran Windows 7 on a 1TB hard drive for a couple years, and then decided this past January to make the upgrade to Windows 8. I also purchased a 128GB SSD for my system. I installed 8 on my SSD and kept 7 on my HDD (to be certain I had all important files backed up). Last night, I felt confident that I had gotten everything I needed, so I reformatted the large partition on that HDD (the smaller one said system reserved, and wouldn't let me format it).

When I rebooted my system, it asked me to choose my operating system. So I went into my boot options and made sure it was looking at the SSD first. I still received the dual boot screen.

Next, I went into disk management and set the system partition on the HDD to inactive. That caused my machine not to boot. I used Partition Wizard to set my SSD to the active partition, but that gave me a boot error that the BootMGR was missing or corrupt. So, I set the HDD system partition back to active, and my machine works all fine and dandy.

Now, how do I get rid of any trace of 7 from my machine? Why won't my machine boot without that HDD partition being active? Are the 8 boot files located there? Any help would be greatly appreciated.

That would only remove the Windows 7 entry on the Windows 7 HDD, & not add the Windows 8 Boot files to the SSD.
