I am trying to install a new larger hard drive while keeping the smaller hard drive for backups. I ghosted the existing drive to the new drive and have them properly set with the new larger drive as master and the older drive as slave. All of my data is showing up on the new drive but the new drive is listed as E instead of C and the pc won't boot from the new drive. If I remove the old drive it won't boot at all. What is going wrong that is preventing it from recognizing the new drive as C? It is listed as master in the cmos.
