> **TLDR:** Make a GRUB CD/USB/floppy bootable image.
>
- Create a bootable ISO from the current directory and save it as `grub.iso`:
  `grub-mkrescue --output {{grub.iso}} .`
- Create an ISO using GRUB files from a custom directory:
  `grub-mkrescue --directory {{/usr/lib/grub/i386-pc}} --output {{grub.iso}} {{path/to/source}}`
- Use compression for GRUB files when building the image, setting `no` disables compression:
  `grub-mkrescue --compress {{no|xz|gz|lzo}} --output {{grub.iso}} {{path/to/source}}`
- Disable the GRUB command-line interface in the generated image:
  `grub-mkrescue --disable-cli --output {{grub.iso}} {{path/to/source}}`
- Preload specific GRUB modules into the image:
  `grub-mkrescue --modules "{{part_gpt iso9660}}" --output {{grub.iso}} {{path/to/source}}`
- Pass additional options directly to `xorriso`:
  `grub-mkrescue --output {{grub.iso}} -- {{volid}} {{volume_name}} {{path/to/source}}`
- Display help:
  `grub-mkrescue {{-?|--help}}`
- Display version:
  `grub-mkrescue --version`
