Img.bz2 To Iso Page
Open your terminal and run:
geteltorito -o your_file.iso your_file.img For total control, mount the image and create a fresh ISO:
bunzip2 your_file.img.bz2 Alternatively, to keep the original compressed file: img.bz2 to iso
dd if=your_file.img of=your_file.iso bs=2048 If this is a hybrid bootable image (common for Linux ISOs that were saved as .img ), use geteltorito :
bunzip2 disk.img.bz2 && mv disk.img disk.iso Wait, does that work? Technically, no—but surprisingly, many raw images will mount just fine with a renamed extension. For professional work, always use the mount + mkisofs method above. Open your terminal and run: geteltorito -o your_file
bzcat your_file.img.bz2 > your_file.img You should now have a standard raw disk image (e.g., your_file.img ). Here is where many guides get it wrong. You cannot simply rename .img to .iso . An ISO is a specific filesystem structure (ISO9660), whereas a raw .img can contain partition tables, boot sectors, or other data.
If you’ve spent any time diving into the depths of Linux recovery forums, virtual machine marketplaces, or legacy software archives, you’ve probably stumbled upon a file with a name ending in .img.bz2 . bzcat your_file
This only works if the .img contains a single filesystem without a partition table.
