FAQs

Does Windows Has an ISO Maker?

Yes. There is a built-in ISO Image Creator in Windows 11 and 10 that helps you create directly an ISO image file from CD, DVD, Blu-ray-ROM. Just select the files and folders you want to include in the ISO image, arrange them within the original directory, rename some of them if necessary, and continue producing the ISO image.

What is the Difference Between ISO and Bootable ISO?

An ISO file, or ISO image, is a type of disk image that contains an exact copy of data from a physical disc, such as a CD, DVD, or Blu-ray disc. It includes the filesystem and all files and folders on the original disc.

A bootable ISO is a specific kind of ISO image. In addition to containing an exact copy of data from a physical disc, it also has the necessary startup information for a computer to boot (start up) from this image instead of its regular operating system when it's burned onto a USB drive or CD/DVD. This feature is often used for installing new operating systems or running live versions of an OS directly from the media without installation.
