How to Create Bootable ISO From Folder

[antdgar]

Searching didn't find any working solutions.

I have the folder and files of an Operating System which I want to make an ISO of.

I want to create a BOOTABLE ISO so I can burn it to DVD and install.

How can I do this? I also have Toast v10

Use Disk Utility.
Go up to File -> New -> New Disk Image From Folder
Choose the drive instead of a folder
Make the image read only or read/write, or CD/DVD ROM master depending on your preference. I usually do read only so the image won't be disturbed, and then I used Disk Utility to "Restore" the image to another partition, usually on an external firewire drive.
Sometimes, after "Restoring" it to an external HD, I open the Startup Disk preference pane and select that partition as a startup disk. I've heard this action "blesses" the partition to make it bootable.

also - in your case, you might want to choose DVD/CD-Rom Master since you'll be burning it.
to burn, you simply drag the image from Finder to the bar on the left in Disk Utility. It may already be there if you created it in Disk Utility.
Select the disk image, then click the Burn button.

I did as you said and Disk Utility created a .cdr file. I burnt this to DVD and it did not give me the option to boot from it... The DVD never appeared at the boot menu.
