ISO files are archive files that contain an exact copy of a CD, DVD, or Blu-ray disc. They are often used to create bootable media, such as USB drives or DVDs, that can be used to install an operating system or repair a computer.
Not all ISO files are bootable. In order to be bootable, an ISO file must contain a boot sector and a partition table. The boot sector is a small program that is loaded into memory when the computer boots up. It then loads the partition table, which contains information about the partitions on the disc.
If an ISO file does not contain a boot sector and a partition table, it will not be bootable. You can use a program such as Rufus or UNetbootin to create a bootable USB drive from an ISO file.
