Windows XP does not natively support AHCI (SATA) or NVMe controllers. Without slipstreamed drivers, the installer will claim it "cannot find any hard disk drives" ( STOP: 0x0000007B ).
Follow on-screen instructions to begin the installation. When prompted, select the partition where you wish to install Windows XP.
XP lacks native drivers for modern AHCI and NVMe storage controllers, resulting in a 0x0000007B BSOD (Inaccessible Boot Device). Prerequisites and Tools Required
