CD-R/RW - if you are creating CD, insert a blank disc so that the program can determine its capacity.
ISO image - having created an ISO disk image, you will be able to burn it onto any kind of recordable DVD, using DVD recording software. Creating a bootable DVD directly from Bootable Media Builder is impossible.
any other media your PC can boot from, such as USB flash drives, etc.
If you use non-optical media, the media must have a FAT file system. This limitation is not applicable for an ISO image.
