How to create image of currently installed ubuntu (on my laptop)? -

-

requirement:

i want copy whole ubuntu (currently using) laptop one.

my idea create image of ubuntu using, install laptop image.

question:

any tools or steps should take ?

you can use remastersys, that's typically used when know you're resintalling many machines same customizations. can find info here: http://debianhelp.wordpress.com/2012/04/20/how-to-install-and-use-remastersys-in-ubuntu-os/

if want clone partition , move new disk, should clonezilla. http://clonezilla.org/

if disks same size , don't want use clonezilla, i've used 'dd' command. convenience, used usb disk docking station 1 http://j.mp/kvmjue. you'll need put image on disk there (since large fit on laptop itself), boot new laptop off live cd, command prompt, , copy image new laptop drive.

for reference, i'd check these places:

here's quote:

making hard disk image file

most of time don't want make complete duplication of hard disk. may prefer creating image file of hard disk , save in other storage devices. following command create image file "disk1.img" in user's directory /dev/sda:

    dd if=/dev/sda of=~/disk1.img

since have created image file, can compress "gzip" or "bzip2":

    gzip disk1.img #generates disk1.img.gz or      bzip2 disk1.img #generates disk1.img.bz2

you can save storage space compression. take long time.

restoring image file

to restore partition or hard disk image file, exchange arguments "if" , "of". example, restore whole hard disk image file "disk1.img":

    dd if=disk1.img of=/dev/sda

restore first partition of /dev/sda image file "disk2.img":

    dd if=disk2.img of=/dev/sda1
