ESD Installer is a native, open-source Windows deployment utility that applies a Windows image directly to a selected existing disk partition, configures boot files, verifies the result, and prepares the computer to boot into the new system without a separate installation USB drive. Three native editions are provided: Windows 10/11 (C#, .NET 8, WinUI 3), Windows 8/8.1 (C#, .NET Framework 4.6.1, WPF), and Windows 7 SP1 (C#, .NET Framework 4.8, WPF). ESD Installer supports ISO/WIM/ESD inspection, real disk and partition enumeration, UEFI/GPT and BIOS/MBR validation, 42 localized application and installer languages, detailed logs, and safety-first immutable planning. WARNING: ESD Installer performs destructive disk operations. Back up important data and verify the selected partition before installation. The author and contributors are not responsible for data loss, unintended wipes, failed storage devices, downtime, or related damage. Released under the MIT License.
