I have an ASUS laptop with 2 Hard drives. The C drive is a 500 GB SSD drive running Windows 10 Enterprise which is now full. I removed the SSD drive and installed a new 2 Terabyte drive as the new C drive. I then installed Windows 10 Enterprise and did all the updates. I then removed the 2 Terabyte drive and re-installed the old 500 GB SSD drive. When I rebooted the Laptop it said, cannot find operating system. I used a portable app to see what was going on and I found the C drive was now called F drive.
Is there a way to have both drives working when they are installed on their own,separately in the Laptop ?
