So i was trying to burn an iso file EXTRACTED to a dvd disc, and i thought that i was burning the iso file to the disc. Than i tried to erase with the burning program (which failed) and Windows had an error "Windows cannot use this disc." So i erased the disc (succeeded this time) and now i'm having an another error. "You need to format this disc in able to use it" So i'm quite mad right now and need some help. And yes IT WAS A DVD+RW DISC. Oh yeah, my os is win 7 64 bit.Just because i'm using my laptop since my pc won't even load the disc.
