How to make a bootable iso in Redhat

By
Sometimes we want to create a bootable CD for installation.

For this reason follow the following steps,

Create a folder/directory named isolinux.

The folder should contain following things taken from OS dump directory.
i)initrd.img
ii)isolinux.bin
iii)isolinux.cfg
iv)linux (Kernel)
v)boot.cat

The above things can be found in isolinux directory of OS dump.

To create a iso file run the following command

mkisofs -o /tmp/DDLJ.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table /root/isolinux

Where
DDLJ.iso = name of the iso
/root/isolinux = Path of the isolinux directory which we created for the iso image.

Now burn the DDLJ.iso to cd.


And boot the machine with this bootable disk.
