Put 2-3 glasses of water in a pan and bring it to boil. Once water starts boiling add washed rice and cook for 10-15 minutes or till rice becomes tender. Keep stirring occasionally and cook on medium flame.
Once rice gets 90% cooked, switch off the flame and immediately strain excess water. Do not over cook rice otherwise it will become mushy while preparing biryani and will not get nice taste.
Spread cooked rice onto big plate to cool down completely. Rice should not be hot while making biryani otherwise it will get break while stirring. You can also use one day before boiled rice.
