|                    Clonezilla GRUB Boot Installer Script                  |
+----------------------------------------------------------------------------+

This script downloads a Clonezilla Live ISO (amd64 or i686), installs it to
/iso/, and adds a new GRUB boot entry to launch Clonezilla at startup.

------------------------------------------------------------------------------

Features:
- Fetches and lists the latest 10 stable Clonezilla releases
- Supports both amd64 and i686 architectures
- Detects if a version is already present:
    - Prompts to reinstall, upgrade, or downgrade
- Adds a GRUB menu entry for booting from ISO
- Simple prompts with safe defaults (non-destructive by default)

------------------------------------------------------------------------------

Notes:
- ISO is downloaded WITHOUT checksum verification – use at your own risk
- Intended for Debian-based systems (Ubuntu, Q4OS, etc.)
- Requires root privileges

------------------------------------------------------------------------------

Requirements:
- bash
- grub2
- wget, curl, dpkg, lsblk, setxkbmap
- GRUB loopback ISO boot support (default for most GRUB2 systems)

------------------------------------------------------------------------------

Usage:
  chmod +x install_clonezilla_boot.sh
  sudo ./install_clonezilla_boot.sh

Follow the prompts to select a Clonezilla version and install the GRUB entry.
