Fortunately there are a few utilities around that can do all of this for us in a single operation.īootable flash devices can be used to install an operating system, which can be particularly useful on a machine that does not have an optical drive. To create a bootable flash device from an ISO file we have to make sure our USB stick or SD memory card is indeed bootable by being partitioned and formatted correctly before we extract and copy all of the individual files to the device. ISO image file is similar to a Zip file in that it holds many separate files that have been packaged up into a single file. The -t iso9660 can be specified as the file system like below.Make a Bootable USB/SD Flash Device from an ISO Image FileĪn.

The file system type of the ISO file can be specified explicitly. sudo -o loop /home/ismail/ubuntu.iso /mnt/isoīy default the ISO file file system type is automatically detected by the mount command. Now we can mount the ISO file but again we require the root privileges. First we will create a directory named /mnt/iso to mount ISO file. The /mnt directory requires root privielges to mount or create directory. Generally physical CD-ROM and ISO files are mounted under the /mnt directory. mount -o loop /home/ismail/ubuntu.iso /home/ismail/cdrom Following ISO mount operation does not require root privileges because the current user has access rights for his/her home directory. We provide the -o loop option and do not provide the sudo command.

In the following example, the ISO file named ubuntu.iso mounted into cdrom directory located in the current user home directory. To mount the ISO file a mount point is required where the contents of the ISO represented. As an ISO file is a file system defined as ISP 9660 or UDF we can use the mount command in order to mount ISO files. The mount command is used to mount different disks and partitions with different file systems. UDF is backward compatible with the ISO 9660. The UDF is the next version of the ISO 9660 standard. ISO 9660 standard created in order to make every CD and DVD content compatible. ISO is a file format and file system which is also defined as ISO 9660. Generally, operating systems, software, software bundles are stored inside ISO files.

ISO files contain the image of a specific CD or DVD. ISO is a popular file format that is generally used to store optical media data like CDs, DVDs, etc.
