I have the command and conquer generals key but not the disk what should i do?

If you have the product key for Command and Conquer: Generals but not the physical disk, you can try downloading a digital version of the game from a legitimate platform, such as Origin or Steam, where you can enter your key to access the game. Alternatively, you might find a copy of the disk from a retailer or an online marketplace. Be cautious of unofficial sources to avoid piracy issues.
