I have 2 internal drives, an SSD with Win7 and HD with my data. I upgraded to Win10, no problem. Because of maleware signs (prior to the upgrade), I wanted to do a clean install using the Windows Media Tool on a DVD. Through bad decisions on my part, I ended up installing Win10 on my HD instead of the SSD. Luckily it did not wipe out my data but I did have backups from 2 weeks ago.
As a result, I was able to dual boot from either drive. Since the HD did not have an OS on it and hence no OS in the Window.old folder, I thought I would reset Win10 and put the HD back to the way it was with no OS. That just reinstalled Win10 again. It may have reinstalled it from the DVD I left in the drive. But now I do not have a dual boot option. It always boots from the HD.
I want to get rid of Win 10 on my HD without losing my data and go back to booting from my SSD. I see some options but not sure which one to follow. Any suggestions on how to proceed?
