Hi All,
I am trying to make a customer ISO. When I run this command: mkisofs -o $DESTINATION_FILE -b isolinux/isolinux.bin -c boot.cat \ -no-emul-boot -boot-info-table \ -V "$NAME" -boot-load-size 4 -boot-info-table -R -J -v -T \ -eltorito-alt-boot -e images/efiboot.img \ $DESTINATION_DIR
it tells me: Size of boot image is 4 sectors -> No emulation Size of boot image is 17408 sectors -> genisoimage: Error - boot image 'images/efiboot.img' has not an allowable size.
This is the exact same file that is on the Everything ISO image.
What am I missing ? I also want to make the ISO boot with UEFI. I think I have the right parameters but getting this error. Thoughts?
Only one thing jumps out to me (no expert at all): Your parameter at call: -boot-load-size 4 Collides with the boot image size of 17408 sectors of the images/efiboot.img file
I would recommend to try with: -boot-load-size 17408 (or even greater)
Have a good day, - Yamaban
