AFAIK you should mount -o loop then copy the intended dirs/files you want to change to another location, change them and then recrate the ISO image.<br />

Can I create ISO using 'dd'?<br />

</div>


<div>
<div class="content wysiwyg-content">
I mounted an ISO image using &quot;-o loop,rw&quot; option.<br />
Then I went into the mounted folder and tried to make a slight change into one of the files. &nbsp;It appears to be still readonly.<br />
<br />
What is the simplest way to modify a inside an ISO. &nbsp;Is there some option like tar does, where I remove that particular file from the ISO and then make changes and add it back to ISO or do I need to extract ISO and make changes and remake it? &nbsp;Please give me step by step process.<br />

Writing on ISO image

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

Unix OS

A Linux distribution is an operating system made as a software collection based on the Linux kernel and, often, on a package management system and are available for a variety of systems. A typical Linux distribution comprises a Linux kernel, GNU tools and libraries, additional software, documentation, a window system (the most common being the X Window System), a window manager, and a desktop environment. Most Linux systems are open-source software made available both as compiled binaries and in source code form, allowing modifications to the original software. Over three hundred distributions are in active development, including commercially backed distributions (such as Fedora, openSUSE and Ubuntu) and community-driven distributions (such as Debian, Slackware, Gentoo and Arch Linux).
