My machine originally had a 7200 RPM HDD with windows 7 installed on it. I recently bought an SSD drive, and decided to upgrade to windows 8, so I installed windows 8 in the new SSD drive.
I could now boot from either the old drive with windows 7, or from the new SSD drive with windows 8. After configuring and updating the windows 8 installation, I copied most of my files from the windows 7 drive.
I didn't need that windows 7 installation anymore, so first I tried deleting the Windows folder along with Program Files and related folders, but the system wouldn't let me. After searching for a bit, I read the only way to remove windows was to format that drive. So I made a backup of all the remaining files that I needed from that drive, but then windows wouldn't let me format the drive nor erase its partition.
Back then I didn't know that there was something called a System Partition that contained the Master Boot Record used to boot the computer, so I messed up and after booting with the Windows 8 installation DVD, I formatted the windows 7 drive that also happened to be the system partition... my computer wouldn't boot anymore.
So I booted again from my Windows 8 DVD but no option from the repair or troubleshooting options would fix the issue. Finally, I had to start a new Windows 8 installation on the formatted drive, and finally it would boot and let me choose to start windows 8 from the SSD drive.
However, now I am back to square one, since I have a fresh windows 8 installation on the old drive that I'd really like erase to reclaim the disk space.
Is there a way to erase the windows installation from that drive (I don't mind if that drive remains as the system partition)?
Or maybe a way to move the System Partition files of the MBR to the SSD drive without losing the data I already installed on it so that I can format the old drive?
