How to create ISO images from your HD CD DVD

[Sniffer]

This is very helpfull to backup you cd and dvd into iso images:

To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it. (ubuntu automount so you need to unmount, that's quite easy, just choose the option unmount from the shell).

dd if=/dev/dvd of=dvd.iso # for dvd
dd if=/dev/cdrom of=cd.iso # for cdrom
dd if=/dev/scd0 of=cd.iso # if cdrom is scsi

To make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the mkisofs command.

mkisofs -o /tmp/cd.iso /tmp/directory/

This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.

For more info, see the man pages for mkisofs, losetup, and dd, or see the CD-Writing-HOWTO at http://www.tldp.org.

Hope it helps

hi,

but as i see it just creates a image from hd/cd...

to make it more fun, how could we make it a bootable/reinstall cd/dvd???

I mean, if we could create a cd.iso from our hd, that could be very nice if we could restore it.

Considering a hard disk crash, what are the best ways to do that ( restore from cd.iso)??

Does anybody have a solution for this that doesn't involve using a 3rd party program?

As someone previously mentioned, try Remastersys:

It *is* third party software, though it's free....

HTH,

Thanks for the input, I ended up using Ghost 4 Linux (G4L).

This is very helpfull to backup you cd and dvd into iso images:

dd if=/dev/dvd of=dvd.iso # for dvd

[Sniffer]

Never tried...but it should work, i presume.

Well I tried to make an iso of my suse 9.3 dvd, this is a dual layer dvd so it contains 8.1Gbyte, If i use dd to make an iso I get about 3.9Gbyte in the iso.

Maybe it can help you out.

Since I always make a back-up copy of my original SuSE dvd's, I looked around if it can be done with the new dual layer dvd as well. And I found an easy and excellent way to do it over at linux-club.de.
All kudos goto "crazyrolf", I just translated his German how-to into English and added a comment or two.

Here it goes:
I found a nice manual how to make a back-up of your SUSE 9.2 DVD that includes only the 32bit version and fits on a single layer dvd. This how to will create an ISO that can be burned to a regular DVD.
This is only intented to be used with legal copies of SuSE 9.2

Some explanations.
Everything will be done in a root shell
# ... is a prompt
Everything to the right of the prompt is an order that has to be executed.
Lines without prompt are just messages that are created during the executions of the orders

Lets start:
First mount the original DVD (if you created an ISO from the original DVD then you must extract that into a folder) with (or similar, that depends on your system)

# mount /cdrom
Now you need to create a new directory on your harddrive (it will take about 4GB). I called mine "/suse92". Lets get to work ( I will not explain the single commands, just use them in the order they are posted but change it for your dvd drive or the folder in case you already extracted the entire dvd):

# mkdir /suse92
# cd /cdrom
# cp -p * /suse92
cp: Verzeichnis ?boot? ausgelassen
cp: Verzeichnis ?docu? ausgelassen
cp: Verzeichnis ?dosutils? ausgelassen
cp: Verzeichnis ?media.1? ausgelassen
cp: Verzeichnis ?suse? ausgelassen
# cp -a boot /suse92
# cp -a docu /suse92
# cp -a dosutils /suse92
# cp -a media.1 /suse92
# mkdir /suse92/suse
# cp -a suse/i586 /suse92/suse
# cp -a suse/i686 /suse92/suse
# cp -a suse/noarch /suse92/suse
# cp -a suse/setup /suse92/suse
# cd /suse92/suse
# mkdir x86_64
# chmod +w *

Now it is time to get rid of the stuff we don't need:

# cd /suse92/suse/i586
# ls aspell-[a-z]*|grep -v -- -de-|grep -v -- -en-|grep -v devel|xargs rm
# ls OpenOffice_org-[a-z]*|egrep -v "(gnome)|(kde)|(Quick)|(-de-)|(-en-)"|xargs rm
# cd /suse92/suse/noarch
# ls ispell-*|grep -v german|xargs rm
# ls yast2-trans-*|egrep -v "(-en)|(-de)"|xargs rm
# ls susetour-[a-z]*|grep -v de|grep -v en|xargs rm
# ls susehelp_[a-z]*|grep -v de|grep -v en|xargs rm
# ls suselinux-adminguide*|egrep -v "(_de)|(_en)"|xargs rm
# ls suselinux-userguide*|egrep -v "(_de)|(_en)"|xargs rm
# ls myspell-*|egrep -v "(german)|(american)|(british)"|xargs rm
# ls k*-i18n*|egrep -v -- "-(de)|(en)"|xargs rm


This last chapter is only valid for the German and English language installation. If you need a different language then you have to make the proper changes.

We are done with the data and it is time to create the ISO

# cd /suse92

ISO Image creation : the next lines are one entire command, that needs to go in one line

# mkisofs -o SuSE_9_2.iso -b boot/loader/isolinux.bin -no-emul-boot -boot-info-table -joliet-long -publisher SuSE -r -V SuSE_9_2 -graft-points /suse92

Done
Burn the DVD and enjoy your back-up.
