Install Windows Xp On Uefi System 2021 Official

If your motherboard (even a 2021 board) retains a Compatibility Support Module (CSM) , you can trick the system into acting like an old BIOS.

  • Boot the USB – you may need to select "UEFI: USB" vs "Legacy: USB." Choose Legacy.
  • Install XP normally – press F6 during blue screen to load SATA drivers (or use a slipstreamed ISO).
  • After install: Never enable Secure Boot again. You will boot via CSM forever.

    • Verdict for 2021: Works on PCs with 6th-gen Intel (Skylake) or older, AMD Ryzen 1000/2000. Most 2021 laptops (Intel 11th-gen, Ryzen 5000) have removed CSM entirely. You cannot use this method on those.
