How I do to modify the contents of a ISO file?

Question

I want to open a ISO file, add files and then burn it to a disc.

By example, I get the Windows98 SE boot disk. That ISO have 2.6mb, and if I burn the iso, I will lost the remainder 697mb of the disk!

To burn the ISO, I use CD Burner XP or ImgBurn, but I don't know which free tool I can use to add/remove files before burn.

Thank you very much!

You can use MagicISO trial version. It's has a 300 MB ISO size limit for the trial version. But it is still worth to try I think. It is still bootable after editing, I've tested it.

Solution 2

You can use your Windows 98 Boot Disk (or any other bootable disk image for that matter) with ImgBurn (which you already have).

Choose Build Mode, add your files and then make it bootable, detailed instructions in this tutorial:

ImgBurn Build Mode - An Overview

1. Mount (using Virtual Clone Drive for example) the .iso files you want and copy all their contents to a new folder.
   OR
   Use a program like 7-Zip to extract the .iso contents to a new folder.

2. Add/remove/modify anything you want in the new folder.

3. Use the free program ImgBurn to "Write files/folders to disc".
   

   • Select the the new folder and/or any other files you want.
     
   • Make the compilation bootable. Go to "advanced" tabs in ImgBurn and then to "Bootable Disc". Check "Make Image Bootable". Detailed instructions for that is here.

4. Burn to a disc.

Solution 4

You can edit any ISO image file contents with WinRAR. Just right click on the ISO image file and select open with WinRAR. That's all.

Solution 5

For Windows, there is no free software that can directly manipulate the contents of an existing ISO file. Of course, there are lots of shareware programs. See the full list with detailed comparison here.

Nice idea, but I need something where I modify the files and not recreate...

I need it "bootable"... :(

i'll try, just wait :)

Second vote for ImgBurn - it really rocks. You can master directly to a CD/DVD or ISO, complete with bootable images. You will need to extract the boot image for your Win98 ISO, which you can even do inside of ImgBurn.

+1 I love imgburn. It's in my top free essential programs.

Oh yes there is. WinISO has been around for years and years.

@barlop WinISO Standard have limitation of 500Mb images. It's a shareware not freeware.

also according to superuser.com/questions/1106632/… a current vresion has a different issue in that it says something was non bootable when it is . so he'll use ultra iso to see if a dvd/cd is bootable.. I've used magic iso to edit ISOs, with no issues, though magic iso is not free either.

Does not work in my experience: The 'Add' button in WinRar is disabled when an .iso-File is open! When you drag a file into WinRar you will get a message that WinRar can only add files to .rar or .zip archives. Tested with version 5.40 and 5.21.

Does not work in my experience neither. The 'Add' button on both WinRar 5.91 and 7Zip 19.00 is not working.

Didn't work with the Free WinISO version 5.3 which rewrites a iso image from scratch instead of editing an existing one, loosing eltorito boot information. UltraISO works great, and works free for ISO images < 300MB (which for my firmware update ISO is enough)

@OrsirisdeJong I wonder if there's an ISO editor that is free (regardless of size), and works.
