1. start the computer.
2. Plug in the USB caddy.
3. Open Disk Management, > go full screen, > take a screenshot and upload in your next reply..
4. Unplug the USB caddy.
You may have already created a Macrium Reflect rescue USB in the past, but, I need you to create a new one running from you new OS drive.
You can use, overwrite the old USB stick.
Please make sure the USB caddy is not connected.
Create a restore point > start MR > create rescue media accepting the defaults.
