This step is critical. You need to enter your UEFI/BIOS settings (usually by pressing Del , F2 , or F12 during boot). Once inside:
What (e.g., Intel 10th Gen, AMD Ryzen 5000) are you targeting?
Because Windows XP cannot load external drivers from a USB port during its initial setup phase, you must integrate the storage and power management drivers directly into the installation files.
Installing Windows XP on a "UEFI-exclusive" (Class 3) system—one without a Compatibility Support Module (CSM)—is one of the most difficult challenges in modern retro-computing. Because Windows XP was designed for the legacy IBM-compatible BIOS, it lacks native support for the UEFI's GUID Partition Table (GPT) and Graphics Output Protocol (GOP).
Plug your prepared USB drive into a if available (Windows XP lacks native USB 3.0 drivers during setup; using a USB 3.0 port may cause the installer to lose track of the drive midway).
