Creating bootable cd or dvd

Copy the image folder from linux dvdor cd by mounting

#          Cp image /root/Desktop

 #         cd /root/Desktop/image

#          cdrecord –v boot.iso

#          Cat diskboot.img > /dev/sda1

Creating image of the dvd

 Insert the dvd or cd and writer this command to create image of disk

#          dd if=/dev/cdwriter /Deepak.iso

Write the image in cd or dvd

#          Cdrecord –v /Deepak.iso

Splitting the dvd image into many parts so that it can be written into cd.

Step 1 create image of the dvd or cd

#        dd if = /dev/cdwriter /vijay.iso

Step 2 to split the image

To manually split the cd according to size

#        split –b 70000 (always in byte) /vijay.iso

Then write the image into blank cd

#        Cdrecord –v /vijay.iso1

To merge the cd into dvd

#        mkisofs –o 1.iso
