OS: rhel 4

bootable cd should be save on the local disk, by using:
1, using cp command OR
2, using dd command (if yes then plz write the syntax also) OR
3, any other method to create the iso image of bootable cd on the local hard disk

Now from the save contents of a bootable cd on the hard disk, I want to create another bootable cd ... plz let me know the command ?

Thanks n Regards

Maaz,

If you have 1 bootable linux cd, simply copy it with gtoaster (comes with Linux) or in a Windows box. It does not matter.

cdrecord can be used to copy cd's on the command line as well.

If you copy a bootable, you end up with a bootable. I would not use cp or dd.

Bootable disk image should be created with dd.

The syntax will be like this:

dd if=/dev/hdc of=/tmp/disk1.iso

You should replace /dev/hdc according to your cdrom device name. That is all.

You can use the mkisofs utility.

I find that if creating a bootable image is difficult in Linux, that using Nero on a windows box is usually a good bet.
