How to Install Windows 11

What Are the Windows 11 Requirements?

Windows 11 only installs on hardware that meets a fixed set of minimums, and two of them, TPM 2.0 and Secure Boot, block many otherwise capable PCs. Run Microsoft’s free PC Health Check app to test your machine in one click before you start.

If PC Health Check reports a problem, it is most often Secure Boot or TPM being disabled rather than missing, and both are usually a quick toggle in the BIOS. A genuinely unsupported CPU is the one barrier you cannot fix through settings.

How Do You Install Windows 11 Step by Step?

A clean install follows six steps: back up, create the USB, enable TPM and Secure Boot, boot from the USB, install, and set up. Set aside about an hour and keep your PC plugged in throughout.

• Back up your files. A clean install erases the drive, so copy documents, photos, and anything else important to an external drive or cloud storage first.
• Create the installation USB. Download the Media Creation Tool from microsoft.com/software-download/windows11, plug in a blank 8 GB or larger USB, run the tool, and let it build the bootable drive. Rufus is an alternative that can also prepare the media.
• Enable TPM and Secure Boot. Restart into the BIOS or UEFI (Delete, F2, F10, or F12 at boot), turn on TPM (PTT on Intel, fTPM on AMD) and Secure Boot, and confirm UEFI mode. Save and exit.
• Boot from the USB. Restart, open the boot menu (often F12 or Esc), and pick the USB drive. The Windows 11 setup loads instead of your old install.
• Install Windows 11. Choose your language, select Custom install, delete the old partitions to wipe the disk, and let setup copy files and restart on its own.
• Complete setup. Pick a region and keyboard, connect to the internet, sign in with a Microsoft account, and choose your privacy settings to reach the desktop.

Making the bootable drive is the step most people get stuck on; the full walkthrough is in how to create a bootable USB. If you want to keep your apps and files instead of wiping the disk, run the installer from inside Windows 10 for an in-place upgrade rather than booting from the USB.

How Do You Enable TPM 2.0 and Secure Boot?

Both settings live in the BIOS, and on most PCs from the last several years the hardware is present but switched off by default.

• Open the BIOS. Restart and press the setup key during boot, usually Delete, F2, F10, or F12 depending on the maker.
• Turn on TPM. Look under Security or Advanced for TPM, PTT (Intel Platform Trust Technology), or fTPM (AMD firmware TPM), and set it to Enabled.
• Turn on Secure Boot. Under Boot or Security, switch the boot mode to UEFI, then enable Secure Boot. It will not turn on while legacy or CSM mode is active.
• Save and verify. Save and exit, boot back into Windows, and re-run PC Health Check to confirm both now pass.

If Secure Boot refuses to enable, the disk is probably still using the older MBR partition style. Windows includes the MBR2GPT tool to convert it to GPT without erasing data, after which Secure Boot becomes available.

How Do You Boot From the USB and Run Setup?

Booting from the USB tells the PC to start the Windows 11 installer instead of the system already on the disk.

• Open the boot menu. With the USB plugged in, restart and tap the boot-menu key (commonly F12, F10, F9, or Esc) before Windows loads.
• Select the USB drive. Choose the USB entry, often shown as UEFI: followed by the drive name, so the firmware boots it in UEFI mode.
• Start the installer. Set language, time, and keyboard, click Install now, and enter or skip the product key if you already hold a digital license.
• Choose Custom. Pick Custom: Install Windows only to do a clean install rather than an upgrade, then select the disk.

From here, deleting the existing partitions and installing onto the unallocated space gives the cleanest result. The full partitioning detail and the difference from an upgrade are covered in how to do a clean install of Windows.

What Should You Do After Installing Windows 11?

A fresh install is not finished until updates and drivers are in, because the USB image is a fixed snapshot that ships without the latest fixes.

• Run Windows Update. Go to Settings, Windows Update, and check repeatedly until it reports no more updates; this also pulls many drivers.
• Install remaining drivers. Get graphics, chipset, and Wi-Fi drivers from the PC or component maker if any device is missing or showing a generic name.
• Restore your files. Copy your backup back, and reinstall the apps you use rather than relying on the old install.
• Confirm activation. Open Settings, System, Activation to check Windows is activated; a digital license tied to your hardware usually activates on its own.

If the result is not what you wanted, you can start over without a USB drive using the built-in reset, explained in how to factory reset Windows.

Should You Bypass the Requirements on an Old PC?

Bypassing the checks works, but it trades Microsoft’s support and update guarantee for the convenience of keeping old hardware.

Last Thoughts on Installing Windows 11

Installing Windows 11 comes down to clearing the hardware gate, then following a clean, repeatable sequence. Confirm TPM 2.0, Secure Boot, and a supported CPU with PC Health Check, back up your files, build an 8 GB USB with the Media Creation Tool, and boot from it to do the install. The two settings that trip people up, TPM and Secure Boot, are almost always a toggle in the BIOS rather than missing hardware.

With Windows 10 out of support since October 2025, the upgrade is now the default path for most working PCs, and bypassing the requirements on older hardware is a fallback rather than a recommendation.

Key Takeaways:

• Windows 11 requires TPM 2.0, Secure Boot, a supported 64-bit CPU (Intel 8th gen or Ryzen 2000 and newer), 4 GB RAM, and 64 GB storage.
• The install sequence is back up, create the USB, enable TPM and Secure Boot, boot from the USB, install, and set up.
• You need a blank USB of at least 8 GB and the Media Creation Tool, or Rufus, to make the bootable drive.
• TPM and Secure Boot are usually present but disabled, and both are a quick toggle in the BIOS.
• A clean install erases the disk, so back up first; an in-place upgrade from inside Windows 10 keeps your files.
• Windows 10 support ended on October 14, 2025; bypassing the requirements works but is unsupported and may miss updates.
