1.3 Installing Debian via Live USB

Linux can be installed natively for the best performance and a full Linux experience.
A Live USB allows you to try Debian without installing, or install it alongside another OS (dual-boot) or as the only OS.

1.3.1 Download Debian ISO​

1.3.2 Create a Bootable USB​

  • Use a USB drive (≥ 8 GB recommended).

Windows Users:

  • Rufus → Select DD mode when flashing Debian images to avoid issues.

Cross-Platform (Windows/macOS/Linux):

Advanced Users (Linux/macOS):

sudo dd if=/path/to/debian-live.iso of=/dev/sdX bs=4M status=progress oflag=sync

Replace /dev/sdX with your USB device path (⚠ careful to avoid data loss).

1.3.3 Boot from USB​

  1. Insert the USB into the target machine.
  2. Reboot and enter BIOS/UEFI boot menu (common keys: ESC, F12, F2, DEL).
  3. Select the USB drive as the boot device.

1.3.4 Start Installation​

  • At the boot menu, choose:

    • Graphical Install → recommended for most users
    • Live system → try Debian first, then install from the desktop

  • Follow the prompts:

    • Select language, location, keyboard
    • Configure network (wired/wireless)
    • Create user account(s) & password(s)

1.3.5 Partition Disks​

  • Guided partitioning → easiest, recommended for beginners.
  • Manual partitioning → for dual-boot setups or custom layouts.

1.3.6 Install System & Bootloader​

  • Installer sets up the base Debian system.
  • Install GRUB bootloader to the main drive (MBR/EFI).

1.3.7 Finalize Installation​

  • Once complete:

    • Remove the USB drive.
    • Reboot into Debian.
    • Log in with your new user credentials.
