Bootable ISOs from a folder

[classbproject]

I used Keka to extract the Debian 11.6 distribution ISO to a folder since I wanted to edit a few files to enable serial console installation. Would the bootable state be retained if I re-archived this to an ISO using Keka?

It will not. You should recreate the original scheme of that ISO image.

Keka creates plain UDF or ISO9660 images.

As an alternative you can recreate it using xorriso like this:

xorriso -as mkisofs \
    -V 'debian-11.6' \
    -e boot/grub/efi.img \
    -no-emul-boot \
    -o <YOUR_DESTIONATION.iso> \
    <YOUR_DEBIAN_FOLDER>

You'll need to install xorriso. Using brew: brew install xorriso
