Hi All,

If I

1) mount a bootable ISO file
mount -t iso9660 -o loop x.iso /mnt/myiso.ios

2) copy the file to a directory
cp -Rip /mnt/myiso.ios /tmp/MyIso/.

3) change some files in the directory (/tmp/MyIso)

4) send the modified directory to cdrecord
cdrecord -v /mnt/myiso.ios

Will I loose the boot portion of the ISO?

Before you use cdrecord, you need to create a new iso file with mkisofs, and you will need to know which file is the boot image for the -b option.



The bell just went off in my head as to what is
going on. My problem is that I can not find the boot image
on the particular ISO I want to manipulate (Kaspersky's
Rescue CD). Since it is a BartPE based disk, I posted over
on the rescue cd forum asking where the boot image resides:

Thank you for help clearing the fog. I bet I will now
understand everything when I (re)read "man mkisofs". :-)
