Dual hard drive installation

Hi yes you don’t want to have 2 different copy’s of windows on the same pc. When you install a program you had before it may use the old windows version. When installing hard drives it is best to only have one drive plugged in for the windows install then add the  other one after. I slipped up once and did not know the second drive had a copy of windows on it and a few programs when I installed them used files from the other windows, delete the windows folder first or format that drive. You can get a boot disk that will format the old drive first.
