Modern systems use AHCI. XP lacks native AHCI drivers, causing the infamous "Blue Screen of Death" (BSOD) during setup. You must inject these drivers.
Installing Windows XP directly onto UEFI hardware ("bare metal") is rarely recommended, as you will likely lack drivers for sound, graphics, and network.

Since modern systems use GPT partition tables and XP only understands MBR natively, the installation strategy usually involves "MBR on UEFI."
Begin by creating a bootable USB drive using software like Rufus or FlashBoot. Format the drive with the MBR partition scheme for BIOS or UEFI-CSM. This ensures your system will recognize it as a valid boot device. A key additional step is to integrate the necessary SATA/AHCI and other drivers into your Windows XP installation media. This is often the difference between success and a "blue screen of death."
: Modern ACPI tables (v6.0+) often crash XP’s ACPI.sys with an "0x000000A5" error. Phase 1: Preparation of Installation Media Follow the on-screen instructions
Troubleshooting tips
: Initialize your target disk as GPT . Use a tool like diskpart to create a 100MB EFI System Partition (FAT32) and a primary NTFS partition for the OS.
: Use tools like nLite or Easy2Boot to slipstream AHCI and NVMe drivers into the ISO. You must inject these drivers
Boot into your system's Boot Menu (usually F11 or F12 ) and select the UEFI partition of your USB drive.
