FlashTitan is a Windows app for making bootable USB drives from operating system images.
It is designed to feel simple for everyday users while still giving advanced users the checks, logs, and diagnostics they need when something goes wrong.
- make bootable USB drives from common OS images
- use a simple three-step flow
- stay focused on removable USB media, not internal drives
- verify finished writes for extra confidence
- collect diagnostics and support bundles when you need help
- Windows 10
- Windows 11
.iso.img.zip.xz.gz
Archive formats are supported when they contain a flashable .iso or .img.
FlashTitan keeps the main path straightforward:
- Choose an image
- Choose the USB drive
- Click
Flash!
If only one safe removable USB drive is connected, FlashTitan can auto-select it after refresh to keep things moving.
- Open FlashTitan as Administrator
- Click
Flash from file - Choose your
.iso,.img, or supported archive - Click
Refresh USB Drivesif needed - Make sure the selected target is your removable USB drive
- Review the erase warning
- Click
Flash! - Wait for writing and verification to finish
- Boot the target computer from the USB drive
FlashTitan includes a preset list for common official downloads.
- Open the preset list
- Choose a preset
- Click
Use preset - If a direct download is available, use
Download image - If the vendor page opens instead, download the image there and then bring it back into FlashTitan
Advanced mode includes support for direct image links when you already know the source you want to use.
FlashTitan is built to reduce common flashing mistakes:
- removable USB drives are the normal target
- internal and likely system drives are blocked in the normal flow
- the selected drive is validated before writing starts
- clear erase warnings are shown before destructive actions
- Administrator rights are required for real writes
No flasher can guarantee boot success on every machine, so final results still depend on the target hardware and firmware settings.
- Windows installer ISOs use a Windows-specific USB creation path
- Linux and hybrid bootable ISOs are usually written directly
- bootable ISOs with valid boot signals can still fall back to raw-write even if they do not match older signatures
.imgfiles are written directly- supported archives are unpacked first, then the flashable image is used
FlashTitan can help you troubleshoot problems with:
- persistent logs
- copied diagnostics snapshots
- support bundles with useful technical details
These tools are helpful when a flash fails, verification reports a mismatch, or you want to share a clean bug report.
Use the Windows installer:
FlashTitan-<version>-Installer.exe
You can also run:
dist/win-unpacked/FlashTitan.exe
This is mainly useful for testing and local packaging checks.
npm install
npm startUseful build commands:
npm run pack
npm run build
npm testFlashTitan is working and usable, but broad public-release confidence still depends on more real hardware validation.
Current limits to keep in mind:
- real-world boot reliability still depends on Windows drive access behavior and the target hardware firmware
- some images still need wider real-device coverage before they should be called broadly proven
- archive extraction depends on the bundled 7-Zip tooling
- the flashing engine is Windows-only in this build
- code signing and broader release polish are still follow-up work
FlashTitan can open Raspberry Pi USB boot documentation, but it does not change Raspberry Pi firmware, EEPROM, or boot order automatically.
