| Method | Difficulty | Reliability | Safe for daily use? | Recommended for 2021 | | :--- | :--- | :--- | :--- | :--- | | CSM / Legacy Boot | Medium | High (on old PCs) | No (security) | ⭐⭐ | | GRUB2 Dual Boot | Very High | Low | No | ⭐ | | VirtualBox / VMware | Low | 99.9% | Yes (isolated) | ⭐⭐⭐⭐⭐ | | UEFI NTFS hack | Extreme | 5% | Hell no | 💀 |
The 2021 answer: Install Windows XP in a virtual machine. You get UEFI compatibility, snapshots, USB passthrough, and zero driver headaches. For the 0.1% of use cases requiring real hardware (e.g., a DOS-era CNC machine), build a dedicated legacy PC and never connect it to the internet.
Warning: Running XP on a modern UEFI system exposes your hardware to unpatched vulnerabilities (EternalBlue, BlueKeep, etc.). If you must dual-boot, air-gap the machine—no Wi-Fi, no Ethernet, no shared folders.
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. install windows xp on uefi system 2021

If you are reading this in 2021, you probably know that Windows XP is a ghost. Official support is long dead, and modern hardware has moved on to UEFI, GPT partition tables, and NVMe drives. Trying to install XP on a new PC usually results in the infamous "No hard drives found" error or an immediate crash on boot.
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. | Method | Difficulty | Reliability | Safe for daily use
For those determined to boot XP in a pure UEFI environment (without CSM), 2021 offered experimental solutions involving modified bootloader files (often based on the UEFI boot manager DUET or specific hacks of the XP kernel).
If you’re a retro-computing enthusiast or need to run legacy industrial software, you might have wondered: Can I install Windows XP on a modern UEFI-based PC in 2021?
The short answer is yes, but it’s not a simple “click and install” process. Windows XP was designed for BIOS and Legacy Boot (MBR partitions). Modern PCs use UEFI (Unified Extensible Firmware Interface) with GPT disks. Windows XP x64 Edition (based on Windows Server 2003) has limited UEFI support, but Windows XP 32-bit has none – it will simply crash on boot. Boot the USB – you may need to
Here’s what you need to know to attempt this in 2021.
In 2017-2019, a hacker named David B. Propper released a proof-of-concept UEFI NTFS driver that could load ntldr. It was called "UEFI Boot XP" and used a custom bootx64.efi.
Why it fails in 2021:
Do not attempt unless you enjoy bricking your motherboard’s NVRAM.
