HDT4ALL

HDT4ALL is a free, open-source hardware detection utility designed to run before Windows starts.

Distributed as a bootable ISO image, it can identify essential PC components even when the installed operating system is damaged, unavailable, or unable to boot.



The utility supports computers using either modern UEFI firmware or traditional Legacy BIOS.

It provides information about the processor, memory, graphics hardware, storage devices, USB peripherals, network adapters, firmware, and system sensors.

This makes it particularly useful for technicians, system builders, repair shops, and advanced users troubleshooting unfamiliar computers.

Unlike conventional Windows hardware tools, HDT4ALL does not need to be installed on the target machine.

It runs from a bootable USB drive, compatible boot manager, or suitable EFI or BIOS partition.

Key Features

• Bootable Hardware Detection: Examines components without loading Windows.
• UEFI Support: Works with PCs configured to use modern UEFI firmware.
• Legacy BIOS Support: Includes an option for older BIOS-based computers.
• System Summary: Presents an overview of the detected computer configuration.
• CPU Information: Displays detailed processor specifications and identification data.
• Memory Detection: Reports installed RAM and related hardware details.
• GPU Identification: Recognizes graphics adapters and display hardware.
• Storage Information: Lists detected hard drives, SSDs, and storage controllers.
• USB Device Detection: Identifies connected USB hardware and peripherals.
• Network Information: Shows network adapters, status, and available parameters.
• Firmware Data: Provides firmware, ACPI, and SMBIOS information.
• Sensor Monitoring: Displays available health and sensor readings.
• Hardware Reports: Produces a comprehensive overview for troubleshooting.
• External Databases: Uses PCI, USB, ACPI, and IEEE databases to identify devices.
• Offline Operation: Does not require an active Internet connection during detection.

User Interface

HDT4ALL uses a functional boot-based interface focused on presenting technical information clearly.



Hardware categories are separated into logical sections, allowing users to inspect individual components or open a complete system report.

The interface is less polished than mainstream Windows utilities, but it is responsive and well suited to repair and diagnostic work.

Some terminology may be difficult for beginners because the program exposes firmware identifiers and other low-level details.

Installation and Setup

HDT4ALL does not use a conventional Windows installer.

Download the ISO image and write it to a USB flash drive using a bootable-media creation utility.

Restart the computer, open its boot menu, and select the prepared USB drive.

Users must choose the appropriate UEFI or Legacy BIOS boot option.

External identification databases can also be updated by replacing the relevant files inside the IDS directory.

How to Use

• Download the HDT4ALL ISO image from FileHorse or official website.
• Insert an empty USB flash drive.
• Write the ISO to the USB drive using a compatible imaging tool.
• Restart the target computer.
• Open the computer’s firmware boot menu.
• Select the HDT4ALL USB device.
• Start the UEFI or Legacy BIOS edition.
• Choose a hardware category from the main interface.
• Review the detected specifications and device identifiers.
• Open the complete report for a broader system overview.

FAQs

Is HDT4ALL a Windows application?
It is intended for Windows-compatible PCs, but it operates independently from Windows by booting directly from removable media.

Can it examine a computer that cannot start Windows?
Yes. This is one of its main advantages because no working operating system is required.

Does HDT4ALL repair faulty hardware?
No. It primarily identifies hardware and reports available technical information. It is not a repair or data-recovery program.

Does it require Internet access?
No. Detection works offline, although updated external databases may improve device-name recognition.

Is it safe to use?
Yes. Its primary function is reading and displaying hardware information rather than modifying disks or firmware.
