Using UNetbootin

UNetbootin is a cross-platform open-source utility that allows you to create bootable USB drives for various Linux distributions, including MiniOS.

Drive Requirements

Drive Size

See Hardware Compatibility Guide for detailed system requirements and drive sizes.

Installing UNetbootin

  1. Download UNetbootin from the official website
  2. Install the program on your system:
    • Windows: Run the installer as administrator
    • Linux: Install from repository or use AppImage
    • macOS: Drag the application to the Applications folder

Creating Bootable USB Drive

  1. Launch UNetbootin as administrator/root
  2. Select image source:
    • Set the toggle to "Disk image"
    • Click the "..." button and select the MiniOS ISO file
  3. Select target device:
    • In the "Drive" list, select your USB drive
    • Ensure the correct device is selected
  4. Start the process: Click "OK"
  5. Wait for completion - the process may take 10-20 minutes

Automatic Change Persistence

UNetbootin automatically formats the drive to FAT32, so MiniOS will use dynfilefs mode for saving changes. This ensures maximum compatibility with various systems, including EFI boot support.

Parameter Configuration (for Advanced Users)

When precise configuration is needed, boot parameters can be used:

  • perchmode=dynfilefs - Dynamically expandable file (default)
  • perchmode=raw - Fixed-size file
  • perchsize=8000 - Data storage space size in MB
