In the first sentence, the word 'walked' is the past tense and in the second sentence, the word 'walked' is the past participle of 'walk' which requires the auxiliary verb 'have' to complete its sense.
In the case of irregular verbs - their past is formed by various means other than adding 'ed...eg drank/drunk, rang/rung, went/gone. The forms are different - sometimes totally, as in 'went/gone' - and the functions of past tense and past participle are also quite different, just as in the example given above of the regular verb 'walk'. Basically, the participle is incomplete and requires an auxiliary - such as have/had - to make it complete.
