  2. Select your USB drive.
  3. Pick Debian Live from the distro dropdown.
  4. Browse and select your downloaded ISO file.
  5. Enable Persistence (Optional) and adjust the size as needed (e.g., 4 GB).
  6. Click Create and wait for the process to complete.
  7. Safely eject your USB stick.

Booting from Bootable USB Debian Live with Persistence

  1. Reboot and boot from USB via BIOS/UEFI.
  2. Choose "Debian Live Persistent" from the YUMI menu.
  3. At the boot screen, press E, append the word persistence to the Linux line, then press Ctrl + X to boot.

Option 3: Write Debian ISO with DD (Advanced Method)

Using dd for Windows

  1. Download dd for Windows.
  2. Insert your USB drive and open a command prompt as Administrator.
  3. Identify your USB device:
    dd --list
  4. Write the ISO to the USB (replace paths accordingly):
    dd if=C:\path\debian-live.iso of=\\?\Device\HarddiskX bs=4M --progress

Using dd on Linux

  1. Insert the USB and locate the device:
    sudo fdisk -l
  2. Unmount the USB drive:
    sudo umount /dev/sdX
  3. Write the ISO:
    sudo dd if=/path/to/debian-live.iso of=/dev/sdX bs=4M status=progress
  4. Flush the write buffer:
    sync

⚠️ Be cautious: The dd command can wipe entire drives if the device path is incorrect. Double check before executing.


Enable Persistence Manually on Debian Live USB

If you've already flashed a Debian Live ISO to USB and want to add a persistence partition, follow these steps.

  1. Boot from the USB and press E at the splash screen. Add toram to the boot line, then press Ctrl + X.
  2. After booting, open a terminal and gain root access:
    sudo su
  3. Create a new partition using fdisk:
    fdisk /dev/sda

    Inside fdisk:

    n   # New partition
    p   # Primary
    Enter (accept default)
    Enter (accept default)
    +6G # Size
    w   # Write changes
  4. Format and label the new partition:
    mkfs.ext3 -L persistence /dev/sda3
  5. Create persistence configuration:
    mkdir /ptmp && mount /dev/sda3 /ptmp
    echo "/ union" > /ptmp/persistence.conf
    umount /dev/sda3
  6. Reboot. At boot screen, press E, add persistence to the boot line, then press Ctrl + X.

To avoid manually editing boot options each time, you can modify the GRUB config to always include the persistence flag.


Final Take: Choosing the Right Method for You

Creating a Debian Live USB is a flexible and powerful way to run or install Debian on nearly any system. Whether you're looking for a plug-and-play tool, multiboot support, or full control over your setup, there's a method that fits your skill level and goals:

  • New to Linux? Use Etcher for its simplicity and minimal setup.
  • Need multiboot or persistence? YUMI (exFAT) offers flexibility and the option to save system changes.
  • Advanced user? The dd command provides precision and control, but be cautious with device paths.

Persistence can make your live USB even more powerful by saving your files, preferences, and changes across reboots. Whether added during setup with YUMI or manually configured afterward, it’s a great way to turn your Debian Live environment into a portable and personal workspace.
