Before you install Windows on the new drive, you have to disconnect the old drive first. You are correct that some boot information could be on the old drive. Then boot with the new drive once the install is complete. If everything looks good then power down and reconnect the old drive.
Hello, I'm currently using a DELL Inspiron 3593 with WD 1TB HDD. I recently purchased a WD SN550 1TB SSD and cloned my HDD to it and tried to boot. Unfortunately, I'm unable to boot to my new SSD. Instead of booting it ends up showing me a big blue screen and nothing happens. Any resolutions for this are highly appreciated!
