How to add a folder/directory in the iso image of linux cd.


Hi all,

Can any one tell me how i should add a directory/folder in the iso image of linux(redhat) cd and keep the image/cd in bootable state.

I have tried the same but after adding the directory say "Extras", i am facing the following error...

Copy the contents of the cd to a directory, add your own directory, recreate the iso with mkisofs

Code:
cd /<mydir>
mkisofs -r -N -allow-leading-dots -d -J -T -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /tmp/newimage.iso
cheers

i was able to create the image file... but if i try to boot from the same in my virtual machine (for testing) it goes in an infinite loop seaching for cd in the cdrom drive....

but in my case i am booting from the newly created image and no from any cd/dvd.

Error message is :
Quote:
The Red Hat Enterprise Linux Server CD was not found in any or your CDROM drives.
Please suggest what to do in this case...

note: I have dowloaded the isoimage and burnt it into a single dvd from which i am able to boot.

You need to ensure that hidden files are also copied to the directory, you're probably missing '.discinfo' from the root of the cd

A slightly different command line :

mkisofs -o /new.iso -b isolinux/isolinux.bin \
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 \
-boot-info-table -J -R -V disks .

I have used the method a couple of times for "non live DVDs / cd" : It works.
