deleted ml off sd card

[tommybest]

Hi, i,ve deleted ml off my sd card, I thought i had ml on another card but have'nt. i got a new camera and deleted the card then decided to sell my other camera , a canon 500d with ML on it. I was going to delete ML from it before selling but don't have ML on any cards. i still have the nightly build I downloaded originally, how do i get this on to the card so i can safely use it to remove ml from the 500D?
