Hi Andrew,
I think the disc that came with the SSD is the misunderstood piece here. If you bought a SSD from a company like Samsung it comes with a disc with additional software for the SSD. You install the additional software after Windows is installed on the SSD.
Here is the step-by-step for installing Windows 10 on a your SSD:
- Have your Windows 10 installer and key handy
- Insert your Windows 10 install media into the PC, but don't run anything yet. Close out of any auto-start windows that pop-up.
- Turn off you PC
- Physically install the SSD into your computer
- Physically disconnect your larger 1TB drive
- Turn on your PC and boot into the Windows 10 installer
- Install Windows on the SSD drive
- After the install is successful, remove the install media and turn off the PC
- Re-connect your 1TB drive
- Turn on your PC
- Make sure your 1TB drive shows up in 'My Computer'
- Insert the DVD that came with your SSD to install the additional software on your PC.
