However, I was thinking about changing the HDD to a CD port using Caddy, then inserting the SSD into the HDD slot. Will that work? And would you mind finding any YouTube tutorials that demonstrate the process? This is your first time, so I appreciate the help!
Avoid modifying your laptop if it's covered by warranty. I advise against altering internal components since previous issues have been problematic. Consider swapping the HDD for an SSD and performing a fresh installation.
You only have a 250GB SSD, which isn’t enough. You also need an additional 1TB HDD.
