backup - Can i create image of my current installed ubuntu so that i can install it on other machine?

I am running Ubuntu 12.04 TLS. Is there a way to produce an ISO installable image of my current system so as I could burn the image on a flash drive and be able to install it on an other PC ? Please provide details. thanks

You need a program that can produce an iso file, and this is Remastersys.

This set of instructions helped me install and run successfully remastersys on Ubuntu 14.04.1 32bit and also successfully make a bootable flash drive with the custom iso I made.

1. Open the Terminal (Press Ctrl+Alt+T) and run

   
   

   sudo apt-get install plymouth-x11
   




2. Go to this link and download remastersys version for 32bit or 64bit system

   
   

   IMPORTANT: I downloaded version 3.0.4-1 i386 and it WORKS
   I checked 3.0.2- version and it doesn't work.




3. Open 'Software & Updates' (search in Dash or in the System's parameters)




4. In 'Software & Updates', go to "Other Software" tab and press "Add..." button




5. Copy/paste this

   
   

   deb http://www.remastersys.com/ubuntu precise main
   

   
   

   and press OK




6. Now look for two lines with "www.remastersys.com/" in the list you can find on the Other tab and make sure you check both boxes. Enter a password if you are asked to.




7. Switch back to Terminal and run

   
   

   sudo apt-get install remastersys-gui
   




8. To open remastersys-gui, you always need root privileges. So do it in the Terminal

   
   

   gksu remastersys-gui
