How to download (concise steps)
Go to the official Rufus download page (official site). Choose the appropriate build (portable recommended). Save the EXE to a known folder. Optionally verify checksum/signature if available. Run the EXE (no install required for portable build); on first run Windows may prompt for administrator permission — allow it to manage drives.
Basic usage
Insert USB drive (backup data first). Launch Rufus as administrator. Select USB device from Device dropdown. Click SELECT to choose an ISO file. Choose Partition scheme and Target system (MBR/BIOS or GPT/UEFI). Set File system (FAT32/NTFS/exFAT) and Volume label. Click START and confirm prompts (may offer to download/add Syslinux/GRUB or convert ISO).
Common warnings and troubleshooting
Back up data — Rufus will erase the USB drive. Some ISOs (large Windows install ISOs) may require NTFS; some UEFI systems require FAT32. If Rufus fails to write, try different USB port/cable, reformat the drive, or run as admin. Secure Boot or anti-malware software can sometimes block creation or booting — adjust BIOS/UEFI settings if needed. Overview — Rufus 3
