One common method involves borrowing EFI bootloader files ( bootmgfw.efi , winload.efi ) from early Windows Vista builds, known as "Longhorn." These experimental files have just enough compatibility to launch the Windows XP kernel. You would need to install XP normally on an MBR drive, then copy these Longhorn EFI boot files onto an EFI System Partition (ESP) and configure them to point to your XP installation.

Installing Windows XP on a modern UEFI system that lacks a Compatibility Support Module (CSM)—often called UEFI Class 3 install windows xp on uefi system exclusive

This is the most direct way to run XP on systems where CSM is physically absent. It involves using a UEFI-compatible bootloader often backported from Windows Vista or Longhorn betas. Requirements UEFI Bootloader : Files like winload.efi
