I have the 64 bit and 32 bit. I just want to make backups of them to an ISO format so I can burn to another disc. How do I go about doing this?
That's what I use for editing ISOs. For creating I use either Alcohol 52% or ImgBurn because I like their interface better.
IMGBURN is great for creating images of CD/DVD's but if you acctually want tinker with the ISO then ultraiso, poweriso or one of the others listed will work. I like UltraISO but everyone has their favorite. Whatever winds up working for you is great.
