Before diving into the installation, make sure you have the following items ready:

  • A compatible PC or laptop: Most computers made after 2012 support UEFI. Check your motherboard or laptop specs to confirm.
  • A blank USB flash drive (8GB or larger): This will hold the Windows 10 installation files.
  • A working internet connection: Needed to download the Windows 10 installer and drivers.
  • Your Windows 10 product key: Optional during installation, but required to activate Windows later. If you’re reinstalling on the same hardware, Windows usually auto-activates.
  • Backup of important data: The installation process will erase everything on the target drive. Save your files to an external drive or cloud storage.
  • Optional: Driver USB: If your system uses specialized hardware (like RAID controllers or NVMe SSDs), download the latest drivers from the manufacturer’s website and save them to a second USB drive.

Having these ready will save you time and prevent frustration mid-installation.

Step 1: Create a Bootable Windows 10 USB Drive

The first step is creating a bootable USB drive with the official Windows 10 installation files. Microsoft provides a free tool called the Media Creation Tool that makes this process simple and reliable.

Download the Media Creation Tool

Go to the official Microsoft Windows 10 download page:
https://www.microsoft.com/software-download/windows10

Click the “Download tool now” button. The file is about 18MB and will save to your Downloads folder.

Run the Tool and Create Installation Media

1. Double-click the downloaded file (MediaCreationToolxxxx.exe) to launch it.
2. Accept the license terms.
3. Select “Create installation media (USB flash drive, DVD, or ISO file) for another PC” and click Next.
4. Choose your preferred language, edition (Home or Pro), and architecture (64-bit is recommended for modern systems). If unsure, leave “Use the recommended options for this PC” checked.
5. Select “USB flash drive” and click Next.
6. Insert your USB drive (8GB or larger) and select it from the list. Warning: All data on this drive will be erased.
7. Click Next and wait while the tool downloads Windows 10 and creates the bootable USB. This may take 15–30 minutes depending on your internet speed.

Once complete, you’ll have a fully bootable Windows 10 USB drive ready for UEFI installation.

Step 2: Configure BIOS/UEFI Settings

Before booting from the USB, you must configure your system’s firmware to support UEFI mode. This ensures Windows installs correctly and takes full advantage of modern hardware features.

Access the UEFI/BIOS Setup

1. Insert the bootable USB drive into a USB port on your computer.
2. Restart your PC.
3. As the system powers on, press the key to enter BIOS/UEFI setup. This is usually F2, F10, Delete, or Esc, depending on your manufacturer. Look for a prompt like “Press F2 to enter Setup” during startup.
4. Once inside, navigate using the arrow keys.

Enable UEFI Mode and Disable Legacy/CSM

Look for a section labeled Boot, Boot Mode, or Startup. You’ll want to:

  • Set Boot Mode to UEFI Only (not Legacy or CSM).
  • Disable CSM (Compatibility Support Module) if available. This prevents the system from booting in Legacy mode.
  • Ensure Secure Boot is Enabled. Windows 10 requires this for UEFI installations.

> 💡 Tip: If you don’t see these options, your system may already be in UEFI mode by default. Check the boot order instead.

Set Boot Priority

In the Boot menu, set your USB drive as the first boot device. This ensures the system boots from the installation media instead of the hard drive.

Save your changes (usually by pressing F10) and exit. Your PC will restart and begin booting from the USB.

Step 3: Begin Windows 10 Installation

Once your system boots from the USB, you’ll see the Windows Setup screen.

Select Language and Preferences

1. Choose your language, time format, and keyboard layout.
2. Click Next.
3. Click Install now.

Enter Your Product Key (Optional)

You’ll be prompted to enter a Windows 10 product key. You can:

  • Enter it now if you have one.
  • Click I don’t have a product key to skip. You can activate Windows later.

> 💡 Note: If you’re reinstalling Windows 10 on the same hardware it was previously activated on, Microsoft’s activation servers will recognize your device and activate automatically.

Accept the License Terms

Read the license terms and click I accept the license terms, then click Next.

Choose Installation Type

Select Custom: Install Windows only (advanced). This gives you full control over partitioning and formatting.

Step 4: Partition and Format the UEFI Boot Disk

This is a critical step. For UEFI systems, your drive must be formatted using the GPT (GUID Partition Table) scheme—not the older MBR format.

Delete Existing Partitions (If Needed)

If your drive has existing partitions:

1. Select each partition and click Delete. This removes all data and converts the drive to unallocated space.
2. Continue until only “Unallocated Space” remains.

> ⚠️ Warning: This erases all data on the drive. Double-check you’ve backed up everything important.

Create New Partitions for UEFI

Windows will automatically create the necessary partitions when you select the unallocated space and click Next. However, here’s what happens behind the scenes:

  • EFI System Partition (ESP): A small FAT32 partition (usually 100–500MB) that stores boot files. Required for UEFI boot.
  • Microsoft Reserved Partition (MSR): A small reserved space used by Windows.
  • Windows Partition: The main C: drive where Windows and your files will be stored.

Simply select the unallocated space and click Next. Windows will handle the rest.

Troubleshooting: Drive Not Showing Up?

If your SSD or HDD doesn’t appear in the list:

  • Check SATA Mode: Go back to UEFI settings and ensure SATA mode is set to AHCI (not IDE or RAID). AHCI is required for modern SSDs and UEFI compatibility.
  • Load Storage Drivers: Click Load driver and browse to your driver USB if you have one. This is common with NVMe drives or RAID configurations.
  • Refresh the List: Click Refresh to reload available drives.

Step 5: Complete the Windows 10 Setup

After partitioning, Windows will begin copying files, installing features, and configuring your system. This process takes 10–20 minutes and includes several automatic restarts.

Initial Setup Screens

Once installation finishes, your PC will reboot (remove the USB when prompted to avoid looping back to setup). You’ll then see the Out-of-Box Experience (OOBE):

1. Region: Select your country or region.
2. Keyboard Layout: Choose your preferred layout (e.g., US QWERTY).
3. Connect to Wi-Fi: Select your network and enter the password. A connection is recommended for updates and activation.
4. Sign in with Microsoft Account: You can sign in with an existing Microsoft account or create a new one. This syncs settings, files, and licenses across devices.
– Alternatively, click Offline account to create a local account (less recommended for most users).
5. Set Up Security: Create a PIN or password for your account.
6. Privacy Settings: Choose your preferences for location, diagnostics, ads, and more. You can adjust these later in Settings.

Wait for Final Configuration

Windows will finalize settings, install updates, and prepare your desktop. This may take a few more minutes.

Step 6: Post-Installation Setup and Optimization

Once Windows 10 is up and running, take a few minutes to optimize your new installation.

Check for Windows Updates

1. Open Settings > Update & Security > Windows Update.
2. Click Check for updates.
3. Install all available updates, including driver updates. This ensures security patches and performance improvements are applied.

Install Device Drivers

While Windows 10 includes generic drivers, you should install the latest ones from your hardware manufacturer:

  • Graphics: Download from NVIDIA, AMD, or Intel.
  • Chipset: Get from your motherboard or laptop manufacturer’s website.
  • Audio, Network, and Peripherals: Install as needed.

> 💡 Tip: Use the manufacturer’s support page and enter your model number to find the correct drivers.

Activate Windows

If you skipped entering a product key earlier:

1. Go to Settings > Update & Security > Activation.
2. Click Change product key and enter your 25-character key.
3. If your hardware was previously activated, Windows should auto-activate once connected to the internet.

Enable Secure Boot (Double-Check)

To confirm Secure Boot is active:

1. Press Windows + R, type msinfo32, and press Enter.
2. Look for Secure Boot State. It should say On.

If it says Off, re-enter UEFI settings and enable it.

Troubleshooting Common UEFI Installation Issues

Even with careful preparation, issues can arise. Here are solutions to the most common problems:

“No device drivers were found” Error

This usually means your storage controller isn’t supported by the default Windows installer.

  • Solution: Download the correct SATA/AHCI or NVMe driver from your motherboard or laptop manufacturer. During setup, click Load driver and browse to the driver folder on a USB.

PC Boots to Black Screen or Loops Back to Setup

  • Cause: USB still inserted or boot order incorrect.
  • Solution: Remove the USB drive after installation and ensure the internal drive is first in the UEFI boot order.

“Windows cannot be installed to this disk” Error

  • Cause: Drive is MBR, not GPT.
  • Solution: In the installer, press Shift + F10 to open Command Prompt. Type: 
    diskpart
list disk
select disk X (replace X with your disk number)
clean
convert gpt
exit

    Then refresh the drive list and try again.

Secure Boot Prevents Installation

  • Cause: Secure Boot is disabled or set to “Other OS” instead of “Windows UEFI”.
  • Solution: Re-enter UEFI settings, enable Secure Boot, and set OS type to Windows UEFI mode.
