How to use a .iso image as a CD-ROM Repository?


I method described by dv3500ea does not working now. (I think it worked in past). It displays a message like:

W: Failed to mount '/dev/sr0' to '/media/apt/' E: Unable to locate any package files, perhaps this is not a Debian Disc or the wrong architecture?

I fount this workaround useful:

After doing dv3500ea's method's first two steps, (I write this again for user's convenience)

sudo mkdir /aptoncd-mountpoint sudo mount /media/USB/aptoncd.iso /aptoncd-mountpoint -o loop

you should run this:

sudo ln -s /aptoncd-mountpoint /media/apt

If it gives you error, saying /media/apt does not exists, create one with this

sudo mkdir /media/apt

Then run the third command of dv5300ea's command(slightly changed):

sudo apt-cdrom add

This should perfectly...

dd is a perfect tool for copy a file, converting and formatting according to the operands. dd command works on Linux and a Unix-like system whose primary job is to convert and copy files. It can create exact CD-ROM ISO image or create a new CD/DVD iso image. This is useful for making a backup, as well as for hard drive installations, require a working the use of ISO images.

How do I use dd command on Linux to create an ISO image?

Put CD or DVD into CDROM/DVDROM drive.

Do not mount CD/DVD. Verify if the cd is mounted or not with the mount command:
$ mount

If CD/DVD was mounted automatically unmount it with the help of umount command:
$ sudo umount /dev/cdrom
$ sudo umount /mnt/cdrom/

Warning: Reading and writing partitions or data from it has the VERY REAL potential to cause DATA LOSS. Use common sense. BACKUP ANYTHING YOU DO NOT WANT TO LOSE! Wrong command line option can result in DATA LOSS.

Creating an

ISO image

is an important step in copying data from one CD/DVD to another, or writing fresh data to one of these storage mediums. An ISO image archives data to be written to a CD/DVD, which can then be burned it using Writer software. ISO images provide an easy way to store data at an intermediate stage before the software writes the data on a disc.

Downloading Writer gives you various options for creating an ISO image. You can choose various writing speeds and methods. It also allows you to create multiple copies of the same data using a single ISO image.

This article explains what an ISO image is, how to create one, and how to burn one onto a CD-ROM or DVD-ROM. It also lists the software and the URLs that can be used for creating an ISO image. The exercise of creating an ISO file is demonstrated with screenshots to make it easier to understand.

Virtual machines have no access to the physical DVD or CD-ROM drive. You can assign virtual drives to virtual machines by offering ISO files containing the image of a DVD or CD-ROM. These image files can be found in the ISOs tab of the storage repository.

You can import ISO files from a web server into Oracle VM Manager. You can then select the installation media as an ISO file when you create a virtual machine. To create a virtual machine using an ISO file, see Section 7.7, “Creating a Virtual Machine”.

To be able to use an ISO file with your virtual machine you must first import the file into an appropriate storage repository, namely one that can be accessed by the server pool where the virtual machine is to be created. If your storage repository uses file-based storage, you can make repository available to multiple server pools, therefore making an ISO file available to multiple server pools. If you...

Quite often people provide information over the Internet using ISO images. ISO is an archive/image of an optical disc. ISO images are typically used to store structured data files for storing on CD/DVD ROM discs. The ISO file format allows for easy storage, transportation and replication of CD/DVD ROM discs.

One way to use CD/DVD images is creating copies on CD/DVD disks. Here you can find how to do that. But also there is a lot of software providing the possibility to mount CD/DVD image as virtual CD/DVD drive. According to my experience, one of the most powerful programs with intuitive graphic user interface is Alcohol 120% of Alcohol Software. Free trial version of this software is downloadable from

Don't use this information for creating illegal copies of CDs/DVDs.

Many of you have been asking how you can create ISO images from CD's, Virtual Floppy Images from floppy disks and create you own bootable CD's....

Firstly, what is an ISO image? An ISO image file is an image of a CD-ROM disk saved in ISO 9660 format. ISO image files are widely used to store CD content of program (installation) as well as data CD's. ISO is a common CD image format for DOS, Windows (Joliet ISO extension) and other operating systems.

Tools for creating ISO images from a CD:

There are a number of tools available for creating ISO images from removable media such as CD's, DVD's, USB keys etc. Here is a selection of ones I have used (in no particular order and noting that some are purchased products):

Undisker: (creates and extracts ISO images)

WinImage: (also creates Floppy Images for Virtual Server / VPC)

You may be prompted for Red Hat Enterprise Linux Installation CD-ROMs during the initial installation to add additional software components or packages. This method can make any ISO, or file based image, available as a device for your guest. This might be useful for installing software from an ISO file or other media source(for example, a downloaded image).

The syntax for adding an ISO image as a new device to a guest is as following:

['file:/var/lib/xen/images/win2003sp1.dsk,hda,w',\ 'file:/xen/trees/ISO/WIN/en_windows_server_2003_with_sp1_standard.iso,hdc:cdrom,r', ]

In the example above you can see how the file en_windows_server_2003_with_sp1_standard.iso has been added to the guest configuration. Once you reboot your guest this ISO image will be configured as a CD Rom driver inside...

Mount the CD image

1) You must login as a root user, if not root user then switch to root user using following command:
$ su -

2) Create the directory i.e. mount point:
# mkdir -p /media/cdrom

3) Use mount command as follows to mount iso file called disk1.iso:
# mount -o loop disk1.iso /media/cdrom

4) Change directory to list files stored inside an ISO image:
# cd /media/cdrom
# ls -l

Edit the /etc/apt/sources.list

Add the following lines to sources.list

deb file:///media/cdrom oldstable main contrib non-free

deb-src file:///media/cdrom oldstable main contrib non-free

Depending on your Debian version and distribution you want to use, oldstable can be substituted.

If you’re even a little tech minded, you would most probably know what an ISO image is by now. A lot of ISO images can be downloaded legally from the internet such as a Windows 7 install DVD, Live Boot CD’s and Antivirus rescue discs which all come in ISO form and you’ll usually have to burn them to CD, or use a utility to write the images to USB stick to test them out.

Sometimes I would like to test an ISO image first before burning it to a CD. Recently I’ve been trying to merge a few ISO images into one to create a multi-boot CD. With the ability to test the ISO image first, I don’t need to waste CD-Rs. Even if I can use CD-RW, it is still inconvenient because I don’t need to waste my time in burning the disc and booting up my computer with the CD-RW.

There are a few ways to actually mount an ISO in Windows to be able to read the contents of it. A portable tool which is able to mount and run the ISO virtually allowing you to test it quickly is MobaLiveCD. While...

An ISO image is an exact copy of the data on an optical disc, such as a CD, DVD, or Blu-ray Disc. Using the right software, you can create ISO images from optical discs and use them in place of the physical discs. "ISO" refers to the International Organization for Standardization, a group that sets common commercial standards. The term is also a reference to the .iso file extension for disc-image files.

Creating an ISO image is an effective way to back up data on an optical disc. To access the data in an ISO image, you can either burn it to a disc or use software to read the contents of the image file as if it were a disc. If you use a disc frequently and you don’t want to have to load and unload it all the time, making and using an ISO image is a convenient alternative. ISO images are also useful for distributing the contents of an optical disc digitally.

You can find many programs that are capable of creating and loading ISO images, including a handful of no-cost...

Mkisofs command in Linux is used to create filesystems for writing on CD-ROM devices. The cdrecord utility will actually burn the disk. The mkisofs command prepares the files to be burnt on the medium. mkisofs creates an iso file, which is the image file (archive) of the optical disk. This article explains this mkisofs tool in Linux.


According to the manual page of mkisofs command

"The mkisofs command creates a hybrid ISO9660/JOLIET/HFS filesystem with optional Rock Ridge attributes."
"mkisofs takes a snapshot of a given directory tree, and generates a binary image which will correspond to an ISO9660 or HFS filesystem when written to a block device."

The ISO9660 filesystem has some limitations

• The filenames must be in 8.3 format, i.e. filename can have maximum 8 characters with 3 characters extension using uppercase letters, numbers and underscore only.

• Maximum directory depth is 8.

• File names cannot have any...

Disk Image is a computer file containing the complete contents and structure of a data storage device. The term has been generalized to cover any such file, whether taken from an actual physical storage device or not. See more...

A common use of disk images is for remote distribution of software such as Linux distributions: installation floppy disks or CD-ROMs can be recorded as disk image files, transferred over the Internet, and the contents of the original disk(s) duplicated exactly by end users with their own floppy or CD-R drives. So, user can burn the images to convert them in LiveCD s, to try an Operating System, without installing it in the hard disk .

Another common use is to provide virtual disk drive space to be used by SystemVirtualization. This can prevent the CD from getting burned or damaged. It can also reduce bulk when one wishes to carry the contents of the CD along with oneself: one can store disk images to a relatively lightweight and bootable...

During my recent activity I have noted to check out how to extract an ISO image in a traditional way using only shell utilities. It turned out to be easier than I thought, so I will present you three different solutions.

Extract an ISO image using p7zip

p7zip is a file archiver which supports most file-system images.

Installation and usage

This solution requires p7zip-full package.

$ sudo apt-get install p7zip-full

Now you can extract image.iso ISO image to the extracted_image directory using the following command.

$ 7z x -oextracted_image image.iso


Extract debian-7.6.0-amd64-CD-1.iso ISO image to the debian_cd1 directory.

If some of you did not know, you can run ISO image files using VirtualBox. This is useful because it saves you time and Cds. A while ago I was working on creating my own Custom Ubuntu LiveCD. There was a lot of trial and error involved, which let me to create numerous ISO images. Imagine if I did not have this capability, how much time I would have wasted restarting the computer every time I had a new CD, or how much time I would have spent burning CD-RWs, or CD-Rs which would have ended up in the garbage. VirtualBox’s advantages are vast; in this tutorial I will show you one of these many advantges: How to run an ISO image using VirtualBox.


In order to run an ISO image you must have a virtual machine already created. As you can see in the picture below, I already have a virtual machine created for Windows 7. Select your image and then click on the “Settings” icon.

Next, in the settings window you are going to select “Storage“. In the...

I got a raw .img image from the Internet Archive and I would like to mount it on my Linux, or at least convert it to an ISO file.

This image works fine under Windows, when using e.g. MagicDisk to emulate a virtual CD drive.

Under Linux, however, most solutions I found on the net do not work here:

Mounting it as an ISO-9660 image (i.e. mount -t iso9660 ...)

Image is not an ISO-9660 file, so it fails:

mount: wrong fs type, bad option, bad superblock on /dev/loop1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so $ dmesg | tail ISOFS: Unable to identify CD-ROM format.

VMware Workstation, Server, and ESX Server can use virtual CD/DVD disks instead of having to insert physical disks. This saves tons of time and trouble. Even better, creating a shared ISO library and all of your Virtualization servers can share that installation media. Let’s find out how to mount these virtual CD/DVD drives in VMware.

What is an .iso File?

An .iso file is a disk image of a ISO 9660 file. In other words, a disk image is a single file that contains everything on an optical disk. It is easy to create these ISO files from your existing optical CD/DVD disks and even easier to mount them in your operating system.

What are the benefits to using .iso files?

No CD/DVD media to storage, search or get scratched Quick access to optical media because you don’t spend as much time searching for it as you might your optical media Higher performance reading of your optical media – reduce the time to install your operating system & applications Share media...

A disk image, in computing, is a computer file containing the contents and structure of a disk volume or of an entire data storage device, such as a hard disk drive, tape drive, floppy disk, optical disc or USB flash drive. A disk image is usually made by creating a sector-by-sector copy of the source medium, thereby perfectly replicating the structure and contents of a storage device independent of the file system. Depending on the disk image format, a disk image may span one or more computer files.

The file format may be an open standard, such as the ISO image format for optical disc images, or a disk image may be unique to a particular software application.

The size can be huge because it contains the contents of an entire disk. To reduce storage requirements, if an imaging utility is filesystem-aware it can omit copying unused space, and it can compress the used space.


Disk images were originally (in the late 1960s) used for backup and...

Holy crap! My rewrite rules are browser sensitive!

It's aggressive browser-caching on Firefox's part. Never mind.


Having issues with my rewrite rules. Trying to keep 404 response down.

I had already created a simple RedirectMatch ruile that would redirect any attempt to access anything in a CD directory tree to a collective, soft-error page:

RedirectMatch 301 ^/23-TheEasternFrontCD/1635TheEasternFrontCD/

It worked fine when I had nothing in those paths to serve.

Now I want to redirect anything except certain files or anything in certain specific directories. If the specified directory or file exists, I want them to be served, but if they don't a catch-all should redirect to the soft-error page.

Choosing an Architecture

Most users of FreeBSD will have hardware for either the amd64, i386, or armv6 architectures.

Modern PCs use the amd64 architecture, including those with Intel® branded processors. Computers with more than 3 GB of memory should use amd64. If the computer is an older, 32-bit only model, use i386. For embedded devices and single-board computers (SBC) such as the Raspberry Pi, Beagle Bone Black, Panda Board, and Zed Board, use the armv6 SD card image which supports ARMv6 and ARMv7 processors.

All other users should reference the complete list of supported FreeBSD platforms.

Choosing an Image

The FreeBSD installer can be downloaded in a number of different formats including CD (disc1), DVD (dvd1), and Network Install (bootonly) sized ISO Disc Images, as well as regular and mini USB memory stick images. Recent versions of FreeBSD are also offered as prebuilt expandable Virtual Machine...

There are literally thousands of Ubuntu programs available to meet the needs of Ubuntu users. Many of these programs are stored in software archives commonly referred to as repositories. Repositories make it easy to install new software, while also providing a high level of security, since the software is thoroughly tested and built specifically for each version of Ubuntu.

Ubuntu distinguishes between software that is "free" and software that is not free. For details of Ubuntu's Free Software Philosophy please see here.

The four main repositories are:

Main - Canonical-supported free and open-source software.

Universe - Community-maintained free and open-source software.

Restricted - Proprietary drivers for devices.

Multiverse - Software restricted by copyright or legal issues.

The Ubuntu Install CDs contain software from the "Main" and "Restricted" repositories, so if you have no internet connection you can still install...

The general procedure to install Ubuntu (or Ubuntu flavour, Kubuntu, Lubuntu, Xubuntu, ...) from a USB flash drive is:

Acquire the correct Ubuntu installation files ('the ISO') Put Ubuntu onto your USB flash drive Configure your computer to boot from USB flash drive and boot from it

Try Ubuntu (Kubuntu, Lubuntu, Xubuntu, ...) before installing it

Install Ubuntu to your internal drive (hard disk drive or solid state drive).

Ubuntu can be installed from a USB flash drive. This may be necessary for netbooks and other computers without CD drives and is handy for others because a USB flash drive is so convenient. Also, you can configure Ubuntu on the USB flash drive to save changes you make, unlike a read-only CD-ROM drive.

Booting from a USB flash drive created with usb-creator alias Startup Disk Creator and mkusb will behave just as if you had booted from the install CD. It will show the language selection and then the install menu, from which you can install...
