Re: iso image

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.

Re: iso image

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.

Re: iso image

You can use the mkisofs utility.

Re: iso image

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