How To Fix Can't Run Windows 11

People are currently reading this guide.

Alright, let's dive into troubleshooting that frustrating "can't run Windows 11" situation. It can be a real headache, but don't worry, we'll go through it step by step.

Step 1: Tell Me What Happens!

To get started, could you describe exactly what happens when you try to run Windows 11? Do you see an error message? Does your computer restart? Does it get stuck on a particular screen, like the manufacturer's logo? The more details you can give me, the better I can help you pinpoint the problem.

Step 2: Initial Quick Checks

While I wait for your description, let's do a few basic checks that might resolve the issue quickly.

2.1. Check the Minimum System Requirements

Windows 11 has specific hardware requirements. It's possible your system doesn't quite meet them. Here's a quick rundown of the key requirements:

Processor: 1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)

RAM: 4 gigabytes (GB)
Storage: 64 GB or larger storage device

System Firmware: UEFI, Secure Boot capable

TPM: Trusted Platform Module (TPM) version 2.0

Graphics card: DirectX 12 compatible graphics / WDDM 2.x driver
Display: >9” with HD Resolution (720p)

You can usually find your system specifications in your computer's BIOS/UEFI settings or by searching for "System Information" in the Windows search bar (if you can access it).

2.2. Ensure Basic Connections

Make sure all essential cables (power, monitor, etc.) are securely connected to your computer. A loose connection can sometimes cause unexpected issues during startup.

2.3. External Devices

Try disconnecting all non-essential external devices like USB drives, printers, and external hard drives. Sometimes, a faulty peripheral can interfere with the boot process.

Step 3: Booting into Safe Mode

Safe Mode starts Windows with a minimal set of drivers and startup programs. This can help you determine if a third-party application or driver is causing the problem.

3.1. How to Enter Safe Mode (if you can access Windows partially):

Press the Windows key + I to open the Settings app.
Click on System.
Scroll down and click on Recovery.

Under "Advanced startup," click on Restart now.

After your PC restarts to the "Choose an option" screen, select Troubleshoot.
Click on Advanced options.
Click on Startup Settings.
Click on Restart.
On the "Startup Settings" screen, press 4 or F4 to start in Safe Mode.

3.2. How to Enter Safe Mode (if Windows doesn't start normally):

Hold the power button down for about 10 seconds to force a shutdown.
Press the power button again to turn on your PC.
As soon as you see the manufacturer's logo, hold the power button down again for about 10 seconds to force another shutdown.
Press the power button again to turn on your PC. Your PC should now enter the Windows Recovery Environment.
In the Windows Recovery Environment, select Troubleshoot.
Click on Advanced options.
Click on Startup Settings.
Click on Restart.
On the "Startup Settings" screen, press 4 or F4 to start in Safe Mode.

3.3. What to Do in Safe Mode:

Check for Recent Software Changes: If you recently installed new software or drivers before the issue started, try uninstalling them.
Run System File Checker (SFC): Open Command Prompt as administrator and type sfc /scannow and press Enter. This tool checks for and repairs corrupted system files.
Check Disk (CHKDSK): Open Command Prompt as administrator and type chkdsk /f /r and press Enter. This tool checks the integrity of your hard drive. You might be asked to schedule it for the next restart; type Y and press Enter, then restart your computer.
Update Drivers: Use Device Manager to check for and update outdated or faulty drivers, especially display, network, and storage drivers.

Step 4: Utilizing the Windows Recovery Environment

If you can't even get into Safe Mode, the Windows Recovery Environment (WinRE) offers several tools that can help. You usually access it by interrupting the normal boot process a few times (as described in section 3.2).

4.1. Startup Repair

This is often the first option to try in WinRE. It automatically diagnoses and fixes common startup problems.

In WinRE, select Troubleshoot.
Click on Startup Repair.
Follow the on-screen instructions.

4.2. System Restore

If you've previously created system restore points, this option can revert your system files and settings to a previous working state without affecting your personal files.

In WinRE, select Troubleshoot.
Click on System Restore.
Follow the on-screen wizard and choose a restore point.

4.3. Uninstall Updates

If the issue started after a recent Windows update, you can try uninstalling the latest quality or feature update.

In WinRE, select Troubleshoot.
Click on Advanced options.
Click on Uninstall updates.
Choose to uninstall the latest quality update or the latest feature update.

4.4. Command Prompt

The Command Prompt in WinRE allows you to run various commands for advanced troubleshooting.

In WinRE, select Troubleshoot.
Click on Advanced options.
Click on Command Prompt.
- You can use sfc /scannow /offbootdir=c:\ /offwindir=c:\windows (assuming your Windows drive is C:) to run System File Checker from WinRE.
- You can use chkdsk c: /f /r (again, assuming C: is your Windows drive) to run Check Disk.
- You can also try to access and back up important files to an external drive using command-line commands like copy.

4.5. Go back to the previous version of Windows

If you recently upgraded to Windows 11 and are experiencing issues, this option allows you to revert to your previous Windows installation (assuming the old installation files are still intact).

In WinRE, select Troubleshoot.
Click on Advanced options.
Click on Go back to the previous version of Windows.

Step 5: Checking BIOS/UEFI Settings

Sometimes, incorrect BIOS/UEFI settings can prevent Windows from running correctly. You usually access these settings by pressing a specific key (like Delete, F2, F12, or Esc) during the computer's startup. The key varies depending on your motherboard manufacturer.

5.1. Boot Order

Ensure that your primary boot device (the drive where Windows 11 is installed) is selected correctly in the boot order.

5.2. UEFI and Secure Boot

As mentioned earlier, Windows 11 requires UEFI and Secure Boot. Make sure these options are enabled in your BIOS/UEFI settings.

5.3. SATA Configuration

Verify that your SATA controller is configured correctly (usually AHCI mode is required for modern operating systems).

Step 6: Considering a Clean Installation

If none of the above steps work, a clean installation of Windows 11 might be your last resort. This will erase all data on your system drive, so make sure you've backed up any important files beforehand. You'll need a bootable USB drive with the Windows 11 installation files. You can create one using the Media Creation Tool from Microsoft's website.

6.1. Creating a Bootable USB Drive:

Go to the official Microsoft website and search for "Download Windows 11."
Download the Media Creation Tool.
Run the tool and follow the on-screen instructions to create a bootable USB drive. You'll need a USB drive with at least 8 GB of free space.

6.2. Performing a Clean Installation:

Boot your computer from the USB drive (you might need to change the boot order in your BIOS/UEFI settings).
Follow the on-screen instructions to install Windows 11.
Be sure to choose the "Custom: Install Windows only (advanced)" option and select your primary system drive to install Windows on. This will format the drive.

Step 7: Hardware Issues

If you've tried everything else and still can't run Windows 11, there might be a hardware problem. This could involve your RAM, hard drive/SSD, motherboard, or other components. Diagnosing hardware issues can be tricky. You might need to run hardware diagnostic tools (often available in the BIOS/UEFI) or consider seeking professional help.
