There are two main ways to create a bootable environment: using the built-in creator for a USB drive or creating a bootable ISO for modern tools like Ventoy. Method 1: Direct Bootable USB Creation (Easiest)

| ⚠️ Issue | Detail | |----------|--------| | | Do NOT use on SSDs — they handle sectors differently; repairing can damage flash controllers. | | Data backup | Although non-destructive, backup critical data first — a failed repair could make data unrecoverable. | | Physical damage | Cannot fix clicking noises, grinding, or complete drive non-detection. | | UEFI Secure Boot | Older ISO versions (based on FreeDOS) may fail on modern UEFI systems without CSM/Legacy mode enabled. | | USB 3.0 boot issues | Some motherboards require USB 2.0 ports for DOS-based tools. |

The tool will now run. If it finds bad sectors, it will attempt to regenerate them.
