Creating Bootable USB Media
Snigdha OS Decentralized images are hybrid ISOs containing both an El Torito boot catalog for optical media and an MBR / GPT partition table for direct raw execution on USB flash drives.
Writing with dd on Linux
Identify your USB device using lsblk (never write to your system drive /dev/sda or /dev/nvme0n1):
lsblk
Assuming your USB drive is /dev/sdb:
sudo dd if=snigdhaos-decentralize-2026.11.13-x86_64.iso of=/dev/sdb bs=4M status=progress conv=fsync oflag=direct
Caution
Double-check the target device identifier before running `dd`. Writing to the wrong disk will overwrite existing operating systems and files irreversibly.
