Did you have Arduino IDE set to Tools->Board->Arduino UNO to upload the ArduinoISP sketch to your UNO?
Did you remember the capacitor between Reset & Gnd on the UNO after uploading the ArduinoISP?
Did you then set Board type to the Tiny85 you want to program empty bootloader to?
Did you burn the bootloader to set the Tiny85 fuses?
Wired up correctly?
Did you use File->Upload Using Programmer to load sketch onto Tiny85?
