"How to download and burn an iso image file" Mini Howto for linux. (I am using ubuntu 7.04 and kde)   Back to Main Page 

This i a very short version, and if you want to know more, go to the Internet etc.

This howto is without any guarantee, and you may use it on your own responsibility only.

There may be errors, but I do not want to use too much time to  write this howto.

My idea is to make documentation, so you can at the least start using the system.

I (66 years old) have abstracted what I find most important, from lots and lots of documentation.

To check specific words you may use: http://en.wikipedia.org/wiki/Main_Page  (search).

It's easiest to print this howto out, to use it, by your side !

An iso image file is a big file which again contains lots of folders and files, typical for burning an installation cd, but the contents

could be any directories and files.

The idea with an iso image is, that it is better to transfer one bil file over the Internet, instead for a lot of small files.

To confirm that the iso file is uncorrupted after transfer, there often is made a MD5 file, containing  a line of letters/numbers, which

is also to be downloaded, and then checked against the iso file.

One way to check this "MD checksum" is to open a konsole and then write "openssl dgst -md5 name_of_image.iso" like this:

Bash konsole: openssl dgst -md5 filename.iso

Then you will get a checksum which could look something like this
1ad3c003xycbe27b3265da23b886d047													Back to Index of page		

If this is the same figures as in the downloaded MD5 file, you know that the contents of the iso has not been fiddled with.

If you use the k3b program to burn the iso image, this checksum will be automatically made, and shown for you to see,

before you press the "Burn" button.

To convert an iso image into its content of files you have to burn it, and for this purpose you use a cd burning program.

If you use the KDE desktop manager the choice of burning program could be K3B, which I find very easy to use.

Other cd burning programs are:

Nero for Windows

BurnCDCC is a free very simple to use iso burning program for Windows: http://www.terabyteunlimited.com/downloads/burncdcc.zip

Open the k3b burning program:

K3b just opened

Then click on "Burn CD Image":

K3b just clicked on "Burn CD Image" button

Now choose the iso image to burn by clicking on the directory folder icon (to the right in the "Image to Burn" window):

K3b Choose image file to burn
Select the image file by clicking on its name (blue color) and then click "OK" button:

K3b image to burn chosen, without empty cd inserted !!

As you can see above, the "Start" button is greyed out (not active), so now insert an empty cd in the cd writer slot:

K3b with empty cd inserted

After the empty cd has been inserted, k3b automatic calculates the MD5 checksum, and you can see it in the window with the vertical

slider (pull the slider down with the mouse).

After you have checked that is the proper MD5 checksum (same as in the downloaded MD5 text file), just press the "Start" button,

and if everything is well the cd writer begins to burn the "iso image":

K3b burning an iso image

Then when the burning is finished, you see "Succes" written (and a sound playing), which tells that the burning was well done

and the cd burner slot is automaic opened (take the cd out, and write a label on it):

K3b burning sucessfull well done


Click on "Close" button, then File - Quit, to close the program.                                                                    Back to Index of page


To download an iso image file of puppy (just an example), go to Google search (www.google.com), and in the search window write:

"puppy download", or maybe "puppy software download", and when you get the result list, choose.

http://www.puppylinux.com/download/downpage.htm - and on this webpage choose e.g.

ftp://ibiblio.org/pub/linux/distributions/puppylinux/:

Here is a clip from this ftp site:

A clip from puppy download site

Most of the download websites on the Internet looks different from each other, but the principle is the same.

Her you see the link to the very iso image, ending on .iso - and to download it just click on it, and then a pup up window will show up

asking you if you want to save the iso image, and just choose the "Save to Disk" button 

Puppy iso image download confirm pup up window

and click "OK" - then the download wil automatic begin (this clip is from Firefox):                                    Back to Index of page
