if by taking image you mean to say you want to take backup of the current OS then you can consider using the 'dd' command: here are some details regarding it: If the existing disk fails, you can boot from the external drive backup and have your system back instantaneously. This series will make a DVD backup of hard drive partition: Code: dd if=/dev/hda3 of=/home/sam/backup_set_1.img bs=1M count=4430 dd if=/dev/hda3 skip=4430 of=/home/sam/backup_set_2.img bs=1M count=4430 dd if=/dev/hda3 skip=8860 of=/home/sam/backup_set_3.img bs=1M count=4430 And so on. This series will burn the images to DVD+/-R/RW: Code: wodim -dev=/dev/hdc --driveropts=burnfree /home/sam/backup_set_1.img and so forth. To restore the from the backup, load the DVDs in order, and use commands like these: Code: dd if=/media/dvd/backup_set_1.img of=/dev/hda3 bs=1M conv=sync,noerror Load another DVD Code: dd if=/media/dvd/backup_set_2.img of=/dev/hda3 seek=4430 bs=1M conv=sync,noerror Load another DVD Code: dd if=/media/dvd/backup_set_3.img of=/dev/hda3 seek=8860 bs=1M conv=sync,noerror and so forth. source: http://www.linuxquestions.org/questions/linux-newbie-8/learn-the-dd-command-362506/ i hope the above link has helped you with your problem :) > > -- > Regards > G.Karthick > 9629214811 > _______________________________________________ > ILUGC Mailing List: > http://www.ae.iitm.ac.in/mailman/listinfo/ilugc -- idlecool _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
