In some rare cases, the drive letter assigned to your physical or virtual CD/DVD drive can interfere with the game's copy protection. Changing the drive letter to something else, like 'R:' or 'S:', can sometimes trick the game's check.

Q: Why does the "NFSU2 Please Insert the Correct CD-ROM" error occur? A: The error occurs when the game is unable to find the original CD-ROM or installation disc.

A: Yes. The only way to play the game without inserting the CD or mounting an ISO file each time is to apply a No-CD crack to your game's SPEED2.EXE file, as detailed in Solution #8.
