Linux ISO help
Quick guides for downloading, verifying and installing Linux ISO images safely. These notes help beginners choose the right image and avoid common installation mistakes.
Create a bootable USB
Use a trusted USB writer such as Ventoy, Rufus, balenaEtcher or Fedora Media Writer. Always select the downloaded ISO and verify that the target USB drive is correct.
ISO vs torrent vs netinstall
An ISO is the standard installer image. A torrent can be faster and easier to resume. A netinstall image is smaller, but downloads packages during installation.
UEFI, BIOS and architecture
Most modern PCs use UEFI and 64-bit images. The labels x86_64 and amd64 usually mean the same 64-bit PC architecture.
