Installing Windows XP directly on a UEFI system is naturally unsupported because Windows XP requires a legacy BIOS and MBR partition scheme. To succeed, you must bridge the gap between modern hardware and the 2001-era operating system. 1. Enable Compatibility Mode (CSM)
Most UEFI firmware includes a Compatibility Support Module (CSM) that emulates a legacy BIOS.
Enter your BIOS/UEFI settings (usually by pressing F2, Del, or Esc during boot).
Look for a "Boot" or "Security" tab and set CSM (or "Legacy Support") to Enabled.
Disable Secure Boot, as it prevents any OS without a modern digital signature from booting. 2. Prepare Installation Media
Standard XP installers lack drivers for modern SATA controllers (AHCI) and USB 3.0 ports.
Integrate SATA Drivers: Use a tool like nLite to "slipstream" AHCI/SATA drivers into your XP ISO. Without these, you will likely encounter a "Blue Screen of Death" (BSOD) with error 0x0000007B during setup.
Use USB 2.0: Windows XP does not natively support USB 3.0. Use a USB 2.0 port and a USB 2.0 flash drive if possible. 3. Configure Storage
Windows XP does not support the GUID Partition Table (GPT) used by UEFI.
The target drive must be initialized as MBR (Master Boot Record).
If the installer doesn't see your drive, go back to BIOS and change the SATA Mode from "AHCI" to "IDE" or "Compatibility" if the option exists. 4. Run the Installer Boot from your prepared USB or CD.
Follow the standard setup prompts. Press F8 to agree to the terms. Format the target partition using the NTFS file system. Alternative: Virtualization (Recommended)
If your hardware is too new (e.g., lacks CSM support or drivers), installing XP as a Virtual Machine is much easier and safer.
Apps like Oracle VirtualBox or VMware Workstation Player allow you to run XP inside your current Windows or Linux desktop without hardware compatibility issues. Install Windows XP - Easy2Boot
Installing Windows XP on a UEFI-only system is a complex technical challenge because XP was never designed to support UEFI or the GPT partition tables it requires . However, you can achieve this by CSM (Compatibility Support Module) if your BIOS allows it, or by using specific patched bootloaders AHCI drivers Essential Requirements A "Patched" ISO
: Original XP discs will often Blue Screen (BSOD) on modern hardware. You need an ISO with integrated (slipstreamed) AHCI/SATA drivers to recognize modern drives. Bootloader Tool : Tools like WinSetupFromUSB

: If your UEFI firmware has a "CSM" or "Legacy" option, enable it; this is the easiest way to make XP "think" it’s on an older BIOS system. Step-by-Step Installation Guide

Easy2Boot handles XP ISOs better. Copy the ISO to the _ISO\WINDOWS\XP folder on an Easy2Boot USB.
