Enter the hero of this story: .
Insert your USB drive. Back up any data on it – the process wipes everything.
Open Rufus.
Under "Device," select your USB drive.
Under "Boot selection," click SELECT and choose your dellbiosreset.iso.
Partition scheme: Choose MBR for older Dell systems (Pre-2020) or GPT for modern XPS/Precision. If unsure, start with MBR.
Click START. If Rufus asks for "DD Image mode" vs "ISO mode," choose DD Mode – this preserves the raw bootloader.
Wait for "READY" in the status bar. Safely eject the USB.
