it still asks me for dvd after i already mounted it?

[AdrianoSofranko]

i have mounted plenty of iso files before but this time when i press autorun after the installation it still asks to insert the dvd. if i have to mount it to a different drive how do i do that because i only have one and thats 'F drive, actually right now i just checked it says insert dvd into drive c but i only have f i am using ultra iso so how do i use that to creat another one thanks
