The mounting of images is a very useful operation. It can allow a user to easily access data on an ISO without the need to burn and waste a disc. It also is much faster when dealing with the need to manage many images at once. These operations can be performed from a graphical user interface (GUI) or from a standard Terminal.

gISOMount is a graphical utility for mounting and managing ISO images with the added ability to calculate md5sums and read volume information.

The default mount point under linux is under ''/media''. To mount an iso file here do the following:
+
To get gISOMount ensure '''Universe''' section of the Ubuntu repositories is enabled in your [[UbuntuHelp:Repositories/Ubuntu|Software Sources]]. Then to install this software in Ubuntu, [[UbuntuHelp:InstallingSoftware#installing-a-package|install the following package]]: '''''[[UbuntuHelp:apt:gisomount|gisomount]]'''''.
 +
The program can then be launched from '''Applications''' -> '''System Tools''' -> '''gISOMountUsage'''.
 +
Usage is straightforward, simply browse to an ISO image on your hard drive and then either mount, calculate the md5 for comparison with a reference, or burn it to a disc. Additionally, once an image is select, the program can read off volume information in the pane. A favourites functionality allows commonly used images to be pulled up quickly.

=== Command Line ===
 +
The default [[UbuntuHelp:Mount|mount point]] for Ubuntu is under ''/media''. It is recommended a user create subdirectories to this folder for mounting to keep things organized. There is no physical limitation preventing mounting to any other directory on a drive.
 +
'''To Mount ''' <<BR>>
 +
To mount the image to a directory is a simple two step procedure. Sudo is required because we are working in directories owned by root. First make a directory with a name that identifies the contents of the ISO, usually its name.
 
<pre><nowiki>
 
<pre><nowiki>
−
sudo mkdir /media/cdimage
+
sudo mkdir /media/example</nowiki></pre>
−
sudo mount -o loop myfile.iso /media/cdimage
+
Then mount the file with the following command to the newly created directory. In the following example, it is assumed that NameOfISO.iso is in the users working directory, if not replace with the absolute path to the file.
−
</nowiki></pre>
+
−
Where myfile.iso is replaced with the file you want to mount.
+
−
To mount the image so that it can be written to do the following instead:
+
 
<pre><nowiki>
 
<pre><nowiki>
−
sudo mkdir /media/cdimage
+
sudo mount -o loop example.iso /media/example </nowiki></pre>
−
sudo mount -o rw,loop myfile.iso /media/cdimage
+
To mount the image so that it can be written to, use the following mount command instead:
−
</nowiki></pre>
+
−
To unmount the image do this:
+
 
<pre><nowiki>
 
<pre><nowiki>
−
sudo umount /media/cdimage
+
sudo mount -o rw,loop example.iso /media/example
−
rmdir /media/cdimage
+
 
</nowiki></pre>
 
</nowiki></pre>
−
=== Other Formats ===
+
'''To Unmount ''' <<BR>>

Other formats of CD or DVD images can be converted to iso and then mounted as above.

Umounting media is simply the reverse. First unmount the image, then remove the directory it was mounted to. Unmounting is universal, it doesn't matter what image was mounted it can be unmounted this way.
