Fix: Oblivion GOTY Expansion Pack Won't Install on Xbox 360

The "Expansion Pack" for Oblivion GOTY (Xbox 360) is on a second disc. It installs to the hard drive. If installation fails, try these fixes:

Common Fixes

1. Clean Disc 2 – Microfiber cloth, radial strokes. Toothpaste polish as last resort.
2. Try Another Xbox 360 – Isolates drive vs. disc issue.
3. Clear System Cache – Settings → System → Storage → Y on HDD → Clear System Cache. Removes corrupt temp files.
4. Delete Partial Install – Storage → Games → Oblivion → Delete "Shivering Isles" / "Knights of the Nine" if present. Re-install.
5. Install Disc 1 First – Some GOTY discs require base game install before expansion disc.
6. Check Region Match – Disc 1 & 2 must be same region (NTSC-U, PAL, NTSC-J). Mixed regions fail.
7. Update Dashboard – Latest dashboard (2.0.17559.0) fixes some install bugs.

What the Expansion Disc Contains

• Knights of the Nine (questline, faction)
• Shivering Isles (new realm, 30+ hours)
• No separate launcher—content merges into main game after install.

Accessing Content After Install

• Load save → Courier delivers "Knights of the Nine" note.
• Fast travel to "Shivering Isles" door (Niben Bay) or wait for "Strange Door" marker.

If Disc Is Damaged Beyond Repair

• Buy replacement Disc 2 on eBay ($5–$15).
• Digital version: Oblivion GOTY is not on Xbox 360 Marketplace (delisted). Only disc.
• PC (Steam/GOG) GOTY includes all DLC natively – best modern option.

Pro Tip: Install to HDD (Disc 1 + Disc 2) for faster loads, less drive wear, quieter play.
