Ok, that's what I've heard but I have no steps for doing that. I'm new to this and would need someone to tell me. Is formatting that drive the way or is there another?
Verify.
Be absolutely sure the system boots up from the new drive on its own, with the old drive physically disconnected.
Assuming this is so...
Reconnect and boot up.
Open Disk Management.
There, you should see all physical drives in the system.
Identify which is the old one.
Right click, and DELETE each partition on that old drive.
