How to create a bootable iso

[Docfxit]

I have an ISO that was created with CTUpdate. I'd like to burn it with ImgBrun and make it bootable.

The iso has in it:

 

Autorun.inf

 

What do I need to do in ImgBurn to make it bootable?

 

Thank you,

Follow this guide and, after step 4, look at the File Sys field: if the image is bootable it'll say ISO9660 (Bootable) in this field.

You don't make an existing ISO bootable, you create a new one and make that bootable.

Thank you for the reply. Mine says ISO9660, Joliet.

 

When I try to boot from the CD it goes straight to the hard drive. When I start the laptop I select an alternate boot device (CD). It doesn't ask me to press any key to boot from the CD. I can boot from an XP Pro CD without any problems.

 

After I select an ISO image.

Since I made this CD I did go into:

Mode,

Build,

Advanced,

Bootable Disk,

Added a check mark in Make Image Bootable,

Changed extract boot image to CD,

Clicked on the Diskette to Extract Boot Image,

Told it where to save it.

 

What I don't know is how to handle the Boot Image or what to select now.

 

Thank you,

And how would a person go about doing that?

You extracted the boot image from which disc? XP Pro? I'm asking because XP Pro's boot image only boot a XP install CD, nothing else.

 

How is the CTUpdate thing supposed to work? You boot in DOS mode and run it? Or something else?
