Boot your system and access the boot menu (usually via F12 , F11 , or F8 ). Select the for your USB drive.
The screen will initialize into the classic blue text-mode Windows Setup. If it loads without a 0xA5 or 0x7B BSOD, your storage and ACPI patches are functioning correctly.
Workaround: Look into community-modified retro graphics wrappers like if you are running inside a specialized hardware wrapper or virtual allocation layer. Internet Connection and Browsing
But for the true enthusiasts, the phrase "it won't work" is just a challenge. Whether you need it for legacy industrial software or just pure nostalgia, here is how you can get Windows XP running on a modern UEFI system.
Create a partition. Note that due to 32-bit limitations and early UEFI constraints, your system boot partition should ideally be under 2TB. Post-Installation Challenges and Drivers install windows xp on uefi system 2021
Installing Windows XP on a UEFI-based system in 2021 (and beyond) is a challenging task because XP was designed for the legacy IBM-compatible BIOS and MBR partition schemes, while modern hardware relies on UEFI and GPT. Despite these barriers, enthusiasts have developed methods to bridge the gap between 2001 software and 2021-era hardware. 1. Preparation: Modified ISOs and Drivers
Because a native installation is so troublesome, most people who need to run XP today turn to one of these more reliable solutions:

He moved the cursor. It was buttery smooth. He had bridged two decades of silicon evolution just to see a green 'Start' button one more time.
I tried the "CSM" (Compatibility Support Module) route, but my 2021 firmware had already started phasing it out. Attempt 2: I followed a lead from a Win-Raid forum thread
The primary obstacle is that Windows XP lacks native support for UEFI Class 3
This is where most 2021 installs fail. Windows XP install media (CD/USB) doesn't have drivers for USB 3.0/3.1 ports or NVMe storage.
