How to Install Windows 11
Installing Windows 11 produces a working operating system on a compatible PC after a hardware check, a backup, bootable media creation, and a guided setup. Windows 11 requires TPM 2.0, Secure Boot, a 64-bit processor on Microsoft’s supported list, 4GB of RAM, and 64GB of storage, so a compatibility check comes before any installation. This article lists every requirement, then walks through the procedure in phases ordered from verification to first boot: check the system requirements with PC Health Check, back up personal files, create installation media with the Media Creation Tool, boot the PC from the USB drive, partition the disk and install Windows, complete the out-of-box experience, and install updates and drivers.
Each phase states its goal and gives the exact steps. The result is a fully updated Windows 11 system ready for sign-in, with personal data preserved through the backup taken before the install begins.
What You Need Before You Start
Installing Windows 11 requires a compatible PC, installation media, and a backup of personal files before the disk is touched. The items required for a Windows 11 installation are listed below, in the order each is needed:
- A compatible PC meets the TPM 2.0, Secure Boot, 4GB RAM, 64GB storage, and supported-CPU requirements that Windows 11 enforces.
- An 8GB or larger USB drive holds the Windows 11 installation files and is erased during media creation.
- A backup of personal files protects documents, photos, and settings, because a clean install erases the target drive.
- A Microsoft account or local account plan determines how sign-in is configured during the out-of-box setup.
- A reliable internet connection downloads the Windows image, updates, and drivers after installation.
- The product key or digital license activates Windows, though a digital license tied to the hardware activates automatically.
A backup taken before installation prevents data loss, so the guide to backing up a computer covers File History, OneDrive, and full-image methods. Readers replacing an existing Windows installation entirely follow the clean install of Windows procedure, which erases the drive rather than upgrading in place.
Check the Windows 11 System Requirements
Checking the system requirements confirms the PC can run Windows 11 before any installation begins, preventing a blocked setup. Windows 11 enforces a stricter hardware list than Windows 10, and Microsoft’s PC Health Check app reports each requirement as a pass or fail. Follow these steps:
- Download PC Health Check from Microsoft’s official Windows 11 page and install the app on the current system.
- Run the compatibility check, which tests TPM 2.0, Secure Boot, the processor, RAM, and storage in one report.
- Enable TPM 2.0 and Secure Boot in the BIOS if the check reports them as off, since many systems ship with both disabled.
- Confirm the processor appears on Microsoft’s supported CPU list, because an unsupported processor blocks the standard installation.
The minimum requirements are 4GB of RAM, 64GB of storage, a 1GHz dual-core 64-bit processor on the supported list, TPM 2.0, UEFI firmware with Secure Boot, and a DirectX 12 graphics adapter. A system that fails the TPM or Secure Boot check often passes after enabling both settings in the firmware, since the hardware is present but switched off by default.
| Requirement | Minimum for Windows 11 |
|---|---|
| Processor | 1GHz, 2+ cores, 64-bit, on Microsoft’s supported list |
| RAM | 4GB |
| Storage | 64GB or larger |
| Firmware | UEFI with Secure Boot capable |
| TPM | Trusted Platform Module version 2.0 |
| Graphics | DirectX 12 compatible, WDDM 2.0 driver |
Back Up Your Personal Files
Backing up personal files protects documents and settings before an installation that can erase the drive. A clean Windows 11 installation removes everything on the target partition, so a verified backup is required before booting from the USB. Follow these steps:
- Copy documents, photos, and videos to an external drive, capturing every personal folder outside the system partition.
- Sync the user folders to OneDrive so files restore automatically after sign-in on the new installation.
- Export browser bookmarks and application settings, since these do not transfer through a clean install.
- Note installed applications and license keys, because each application reinstalls after Windows 11 is in place.
A full disk image captures the entire system rather than selected files, which the computer backup guide explains alongside File History and OneDrive. Verifying that the backup opens and reads correctly before installation prevents discovering a failed copy after the drive is erased.
Create the Windows 11 Installation Media
Creating installation media writes the Windows 11 setup files to a USB drive the PC can boot from. Microsoft’s Media Creation Tool downloads the Windows 11 image and formats an 8GB or larger USB drive into bootable installation media. Follow these steps:

- Download the Media Creation Tool from Microsoft’s official Windows 11 software download page.
- Insert an 8GB or larger USB drive, accepting that the tool erases every file already on the drive.
- Select USB flash drive as the media type, then choose the language and edition that match the license.
- Let the tool download and write the files, which produces a bootable Windows 11 USB drive when it finishes.
The Media Creation Tool is one of two standard methods, and the guide to creating a bootable USB drive covers both the Media Creation Tool and Rufus with a downloaded ISO, including the GPT and UEFI settings Windows 11 requires. A drive created with the wrong partition scheme fails to boot on a UEFI system.
Boot the PC From the USB Drive
Booting from the USB drive starts the Windows 11 installer instead of the existing operating system. The PC normally boots from its internal drive, so the firmware must be told to start from the USB drive through a one-time boot menu or a changed boot order. Follow these steps:

- Insert the bootable USB drive into a USB port and restart the PC.
- Press the boot menu key at startup, commonly F12, F10, Esc, or F9 depending on the manufacturer.
- Select the USB drive from the boot menu, choosing the UEFI entry rather than the legacy entry for a Windows 11 installation.
- Change the boot order in BIOS if no one-time menu appears, setting the USB drive above the internal drive.
The PC loads the Windows 11 setup screen when the boot from USB succeeds, showing the language and region selection. A system that boots back into the existing operating system did not select the USB drive, so the boot menu or boot order needs a second attempt.
Partition the Disk and Install Windows 11
Partitioning the disk and running setup writes a fresh copy of Windows 11 to the chosen drive. The Windows 11 installer offers an upgrade that keeps files or a custom install that lets the disk be partitioned.
The custom install supports a clean layout on the target drive. Follow these steps:
- Select the language, time, and keyboard layout, then click Install now on the setup screen.
- Enter the product key or select ‘I don’t have a product key’ if the license activates digitally after installation.
- Choose Custom: Install Windows only to reach the partition screen, rather than the upgrade option.
- Select the target drive, delete old partitions if a clean layout is wanted, and click Next to begin copying files.
Deleting existing partitions erases all data on that drive, so this step relies on the backup taken earlier. Selecting unallocated space lets the installer create the system and recovery partitions automatically. The detailed partition-deletion sequence for a full wipe appears in the clean install of Windows guide, which targets erasing the entire drive.
Complete the Out-of-Box Setup
Completing the out-of-box experience configures the region, account, and privacy settings on first boot. After the files copy and the PC restarts, Windows 11 runs the out-of-box experience, a guided sequence that prepares the desktop for first use. Follow these steps:
- Select the country, language, and keyboard layout, which set the regional formats for the new installation.
- Connect to a network, since Windows 11 Home requires internet and a Microsoft account during setup.
- Sign in with a Microsoft account or configure a local account, depending on the sign-in plan chosen earlier.
- Review the privacy settings for location, diagnostics, and advertising ID, then reach the Windows 11 desktop.
Windows 11 Home editions require a Microsoft account and internet connection to finish the out-of-box experience, while Pro editions allow a local account. The desktop appears once the out-of-box experience completes, marking the point where updates and drivers are installed next.
Install Updates and Drivers
Installing updates and drivers brings the new Windows 11 system current and enables every hardware component. A fresh installation includes generic drivers, so Windows Update and the manufacturer sites supply the latest security patches and device drivers. Follow these steps:
- Open Settings, then Windows Update, and click Check for updates to install the latest security and quality updates.
- Install optional driver updates from Windows Update under Advanced options, then Optional updates.
- Download the chipset and graphics drivers from the motherboard and GPU manufacturer sites for full hardware support.
- Restart when prompted, then recheck Windows Update until no further updates remain.
Drivers from the device manufacturer often outpace the versions in Windows Update, especially for graphics cards, which the guide to updating drivers in Windows covers across Windows Update, Device Manager, and manufacturer tools. A graphics driver from the GPU maker enables full display performance that the generic Microsoft driver does not.
Key Takeaways
- Check TPM 2.0, Secure Boot, and the CPU list first with PC Health Check, since Windows 11 blocks installation on unsupported hardware.
- Back up personal files before starting, because a clean Windows 11 install erases the target drive.
- Create installation media with the Media Creation Tool on an 8GB or larger USB drive.
- Boot from the USB drive through the firmware boot menu, choosing the UEFI entry.
- Use the Custom install to partition the disk and write a fresh copy of Windows 11.
- Install Windows Update and manufacturer drivers to complete the system and enable every component.
What are the minimum requirements for Windows 11?
Windows 11 requires TPM 2.0, Secure Boot, a supported 64-bit CPU, 4GB of RAM, 64GB of storage, UEFI firmware, and a DirectX 12 graphics adapter. PC Health Check reports each one.
Do I need TPM 2.0 to install Windows 11?
Yes. Windows 11 requires TPM 2.0 and Secure Boot. Many systems ship with both disabled in the BIOS, so enabling them in the firmware often allows the installation to proceed.
How big a USB drive do I need for Windows 11?
An 8GB or larger USB drive holds the Windows 11 installation files. The Media Creation Tool erases the drive during creation, so back up any files on it first.
Can I install Windows 11 without a product key?
Yes. Select ‘I don’t have a product key’ during setup. A digital license tied to the hardware activates automatically after installation, or a key activates Windows later in Settings.
Does installing Windows 11 erase my files?
A custom install with deleted partitions erases the drive. An upgrade keeps files and apps. Back up personal data before starting, since a clean install removes everything on the target.
Which boot menu key starts the USB installer?
The boot menu key is commonly F12, F10, Esc, or F9, depending on the manufacturer. Press it at startup and select the UEFI USB entry to launch the Windows 11 installer.
Last Thoughts on Installing Windows 11
Installing Windows 11 follows a fixed order: confirm the hardware meets the TPM 2.0, Secure Boot, and CPU requirements, back up personal files, create bootable media with the Media Creation Tool, boot from the USB drive, partition the disk through the Custom install, complete the out-of-box experience, and finish with Windows Update and manufacturer drivers. Each phase depends on the one before, and the backup protects data through the partition step.
