Installing Windows XP on a "UEFI-exclusive" (Class 3) system—one without a Compatibility Support Module (CSM)—is one of the most difficult challenges in modern retro-computing. Because Windows XP was designed for the legacy IBM-compatible BIOS, it lacks native support for the UEFI's GUID Partition Table (GPT) and Graphics Output Protocol (GOP).
Click , choose Multiple driver folder , and select your downloaded modded SATA AHCI or NVMe controller drivers.
If your motherboard has (common on 2020+ Intel and AMD systems), you have only two choices:
This guide explores the "exclusive" methods to make this happen, walking you through the most viable approaches, from the recommended Legacy/CSM path to the more advanced pure UEFI hacks.
This comprehensive, step-by-step guide covers the exact methods, custom loaders, and driver integrations required to natively boot and install Windows XP on an exclusive UEFI system. Phase 1: Understanding the Hardware Constraints install windows xp on uefi system exclusive
What is the exact you are using?
Open VirtualBox, click "New," name it "Windows XP," and select the Windows XP (32-bit or 64-bit) version.
Your chances of success largely depend on your motherboard's UEFI implementation. The industry has defined three classes of UEFI firmware, and knowing where your system falls is essential.
Power on the PC and access the boot menu. Select the for your USB drive. Installing Windows XP on a "UEFI-exclusive" (Class 3)
You must disable Secure Boot in your UEFI/BIOS settings.
Let us know in the comments if you had to use the OpenCore method or if your board still supported the elusive CSM mode.
If you hit a BSOD 0x7B, your AHCI/NVMe drivers are incorrect. If you hit a BSOD 0xA5, your ACPI.sys patch is not working.
Successfully booting into the Windows XP desktop is only half the battle. The system will run without network, audio, chipset, or graphics acceleration. Finding XP-compatible drivers for modern hardware is a scavenger hunt. Graphics cards newer than 2013 rarely offer XP drivers; the best bet is a legacy GPU like the NVIDIA GeForce 900 series or AMD Radeon HD 7000 series. Realtek HD Audio and Intel I219-V Ethernet have no XP drivers, forcing users to rely on discrete PCIe sound or network cards. Most critically, Advanced Configuration and Power Interface (ACPI) issues cause random blue screens or shutdown failures. The solution involves forcing a Standard PC HAL (Hardware Abstraction Layer) during installation by pressing F5 when prompted—a hidden feature that disables multi-core support and power management. The exclusive result is a single-core, non-ACPI, unaccelerated XP environment running on a 12th-generation Intel Core processor—a technical marvel of inefficiency.

Windows XP, on the other hand, is an outdated operating system that was released in 2001. It was designed to work with traditional BIOS systems and does not have native support for UEFI. However, with some modifications and workarounds, it is possible to install Windows XP on a UEFI system.
