Okay I have more then enough 700 MB discs, but when I drag the windows 7 RC file it says I need 1.69 GB more. Can't I use more then one disc? I ask this because for my computer recovery discs they used 14 700 MB discs. No I am not trying to burn it them. I just need to know how can I burn Windows 7 RC to several 700 MD discs.
