Solution 1: Redeem Your Code for a Digital Version (Recommended)
Because the official patches for The Sims Medieval are old, you may need a community-approved fix. This does mean using cracks from pirate sites (which are dangerous). Instead, use the official Swarm Patch or the EA Unwrapper .
Sometimes the error is triggered by the game's launcher rather than the game itself. You can bypass the launcher by running the game executable directly.
The "No Disc Found" error is exclusively a problem for the physical disc version of the game. The digital versions sold on platforms like or Origin (EA App) do not use disc checks. They are patched, DRM-managed by the launcher, and compatible with modern systems.
If you love the game and want to support the developers (or just want a hassle-free experience), repurchasing the digital "Pirates and Nobles" expansion pack or the base game on Steam is the most guaranteed way to solve the error permanently. It also saves you from having to use a No-CD fix every time you reinstall.
