My original HD started to fail check disk scans and I decided to replace it. I bought a Western Digital HD and have never had issues before. Used the Acronis tool that was provided to copy files from the old HD to the new one. After it completed the process and restarted everything looked fine so I turned off the system to remove the old failing HD. When I rebooted with only the new drive plugged in my windows loaded, but it was like super basic almost like a first time install. I shut it back down and plugged both drives in and started it back up and it loaded just fine and everything was there again. So I shut it back down and unplugged the new HD and tried to boot with only the old HD, but no bootable info found and it was stuck. The computer will only work if both hard drives are plugged in. I thought maybe I could do a windows restore from backup with only the new HD plugged in and windows would understand I only want the new HD. Windows restore would not work until I plugged both HDs in it kept saying missing component. I dont want to have to re-install windows to get rid of the faulty HD, but my system has become dependent on it. Is there anything I can do to fix this?
