Enhance boot configuration for custom ISO with USB delay and filesystem support

- Added isofs module to boot configurations for both UEFI (GRUB) and Legacy BIOS (Syslinux) to enable ISO9660 filesystem support. - Updated boot parameters to improve USB delay and debugging capabilities for better hardware compatibility.
