Install Windows 11 24H2 on a Supported PC

This guide walks you through installing Windows 11 version 24H2 on a PC that meets Microsoft’s official hardware requirements. You’ll learn how to prepare, perform a clean install or upgrade, and avoid common pitfalls. Before starting, back up your important files and ensure you have a stable internet connection.

What You’ll Need

A PC that meets Windows 11 minimum requirements (CPU, RAM, storage, TPM 2.0, Secure Boot capable UEFI).
A USB flash drive with at least 8 GB of space (for creating installation media).
Another working computer to download the installation files.
Your Windows product key (if you’re doing a clean install and need to activate).

Step-by-Step

Check compatibility. Download and run the PC Health Check app from Microsoft’s website. It will tell you if your PC can run Windows 11. Pay attention to TPM and Secure Boot status.
Back up your data. Use an external drive or cloud storage to save documents, photos, and any other files you can’t afford to lose.
Create installation media. On your working computer, go to Microsoft’s Windows 11 download page. Under “Create Windows 11 Installation Media,” click “Download Now.” Run the tool, accept the terms, and choose “Create installation media for another PC.” Select language and edition (Windows 11), then choose “USB flash drive.” Insert your USB drive and follow the prompts to write the installer to it.
Prepare your PC. Plug the USB drive into the PC where you want to install Windows 11. Restart the PC and enter the boot menu (often by pressing F12, Esc, or Del during startup). Select the USB drive as the boot device.
Start the installer. The Windows Setup screen will appear. Choose your language and click “Next,” then “Install Now.” If prompted, enter your product key, or click “I don’t have a product key” to continue (you can activate later).
Choose installation type. For a clean install, select “Custom: Install Windows only (advanced).” This wipes the current OS and installs fresh. For an upgrade, run the setup from within Windows and choose “Upgrade: Keep files and apps.”
Select the drive. In the custom install screen, you’ll see a list of partitions. Select the partition that contains your current Windows (usually the largest) and click “Format” (this erases everything on that partition). Then click “Next.” If the installer complains about GPT or MBR, you may need to delete all partitions on the drive and let Windows create new ones—this erases all data, so be sure.
Wait for installation. Windows will copy files, install features, and restart several times. Leave the PC alone during this process, which can take 10-30 minutes.
Complete setup. After installation, you’ll go through the Out-of-Box Experience: choose region, keyboard layout, sign in with a Microsoft account (or local account, if available), and set up a PIN. Follow the prompts until you reach the desktop.
Check for updates. Once on the desktop, go to Settings > Windows Update and click “Check for updates.” Install all pending updates, including the 24H2 feature update if not already included.

Common Mistakes

Skipping compatibility check. Trying to install on unsupported hardware leads to errors or a blocked installation.
Not backing up. Formatting the wrong drive or a failed install can result in total data loss.
Choosing the wrong boot device. If the PC boots from the hard drive instead of USB, the installer won’t start.
Selecting “Upgrade” when you want a clean install. Upgrade keeps old files and settings, which can cause issues if you’re trying to fix a broken system.
Forgetting to remove the USB drive after installation. This can cause the PC to boot from the USB again, leading to a loop.

Tips

Use a USB 3.0 drive for faster installation.
If your PC has an SSD, ensure it’s connected to a SATA port that supports AHCI mode (check BIOS).
During installation, you can press Shift+F10 to open Command Prompt for advanced disk management.
If you’re upgrading from Windows 10, make sure you’re on the latest version (22H2) before attempting the upgrade.
After installation, visit the manufacturer’s website to download the latest drivers for your specific model.

Troubleshooting

Installation fails with “This PC can’t run Windows 11.” Re-run PC Health Check. If TPM is off, enable it in BIOS (look for “Intel Platform Trust Technology” or “AMD fTPM”). Ensure Secure Boot is enabled. If your CPU is unsupported, you may need to use a workaround (not covered here).
Boot from USB doesn’t work. Check the boot order in BIOS. Disable Secure Boot temporarily if it’s blocking the USB. Try a different USB port (preferably USB 2.0).
Windows Setup freezes or crashes. Remove unnecessary peripherals, ensure your RAM is working (try one stick), and try a different USB drive or re-create the media.
After install, you see “Windows can’t activate.” If you upgraded from a genuine Windows 10, activation should be automatic. If not, go to Settings > System > Activation and troubleshoot. For clean installs, enter your product key.
No network after install. Install the network driver from your PC manufacturer’s website (download on another device and transfer via USB).

Frequently Asked Questions

Is Windows 11 24H2 a free upgrade?

Yes, if you have a genuine Windows 10 or Windows 11 license, the upgrade to 24H2 is free.

Do I need to reinstall my apps after a clean install?
