Installing Windows 11 is usually a smooth process, but sometimes the installation can become stuck at a certain percentage, freeze on a loading screen, remain on “Getting Ready,” or stop responding altogether. This issue can occur during a clean installation, an upgrade from Windows 10, or while installing a major Windows 11 feature update.
A stuck installation can be frustrating, especially if it remains at the same percentage for hours without any visible progress. In some cases, the installation may actually be working in the background, while in others, hardware conflicts, corrupted installation files, insufficient storage, or software issues may be preventing Windows from completing the process.
The good news is that most Windows 11 installation problems can be fixed without replacing hardware or performing advanced repairs. In this guide, we’ll cover the eight best methods to resolve a Windows 11 installation that is stuck and get your PC running normally again.
Why Does Windows 11 Installation Get Stuck?
Before applying fixes, it’s useful to understand some common causes:
- Corrupted installation files
- Insufficient disk space
- Faulty USB installation media
- Damaged system files
- Outdated BIOS or firmware
- Hardware compatibility issues
- Faulty RAM or storage drive
- Peripheral device conflicts
- Interrupted Windows Update services
- Third-party antivirus interference
Identifying the root cause can help prevent the issue from occurring again.
Method 1: Wait Longer and Check for Disk Activity
Sometimes Windows 11 appears frozen when it is actually processing files in the background.
Large updates and clean installations may take considerably longer on older hard drives, low-end processors, or systems with limited memory. Even if the percentage remains unchanged for an extended period, Windows may still be working.
Before forcing a restart:
- Check the hard drive activity light.
- Listen for storage activity.
- Wait at least 30–60 minutes if progress recently changed.
- Leave the computer connected to power.
If there is ongoing disk activity, Windows may still be installing files.
Only proceed with additional fixes if there has been no progress for an extended period.
Method 2: Disconnect Unnecessary External Devices
Peripheral devices can sometimes interfere with the installation process.
Disconnect all non-essential hardware, including:
- USB drives
- External hard drives
- Printers
- Scanners
- Webcams
- Game controllers
- USB hubs
- SD cards
Keep only:
- Keyboard
- Mouse
- Display
- Installation media (if needed)
After disconnecting peripherals, restart the installation.
Hardware conflicts frequently cause installation freezes during setup.
Method 3: Verify Available Storage Space
Windows 11 requires adequate free space to complete installation successfully.
Check Storage Requirements
Generally, Windows 11 requires:
- At least 64 GB of storage
- Additional free space for updates and temporary files
If upgrading from an existing Windows installation:
- Open File Explorer.
- Check the available space on the system drive.
- Delete unnecessary files if storage is low.
- Empty the Recycle Bin.
- Run Disk Cleanup.
Low disk space is one of the most common reasons installation stalls unexpectedly.
Method 4: Recreate the Installation Media
Corrupted installation media can cause setup failures and freezing.
Create New Installation Media
- Download the latest Windows 11 ISO.
- Use the Media Creation Tool.
- Create a fresh bootable USB drive.
- Use a reliable USB flash drive.
- Prefer USB 3.0 devices from reputable brands.
If your current installation media is damaged, recreating it often resolves setup issues immediately.
This method is especially useful when installation repeatedly freezes at the same percentage.
Method 5: Run Startup Repair
If the installation became stuck after a restart, Startup Repair may help.
Launch Startup Repair
- Boot into Windows Recovery Environment.
- Select Troubleshoot.
- Click Advanced Options.
- Choose Startup Repair.
- Select the Windows installation.
Windows will automatically scan for startup-related problems and attempt repairs.
After Startup Repair completes, try running the installation again.
This method is particularly effective when boot files become corrupted during setup.
Method 6: Check RAM and Storage for Errors
Faulty hardware can prevent Windows installation from completing.
Test Memory
- Press Windows + R.
- Type:
mdsched.exe- Press Enter.
- Choose Restart Now and Check for Problems.
Check the Storage Drive
Open Command Prompt as Administrator and run:
chkdsk C: /f /rAllow the scan to complete.
Memory errors and bad sectors frequently cause installations to freeze or fail unexpectedly.
Method 7: Update BIOS and Reset BIOS Settings
An outdated BIOS can create compatibility issues with Windows 11.
Update BIOS
- Visit your motherboard or laptop manufacturer’s website.
- Download the latest BIOS update.
- Follow the manufacturer’s instructions carefully.
Reset BIOS to Default
If settings have been modified:
- Enter BIOS setup.
- Load default settings.
- Save changes.
- Restart the PC.
Incorrect BIOS settings can interfere with TPM, Secure Boot, storage controllers, and installation compatibility.
Updating firmware often resolves unexplained setup problems.
Method 8: Perform a Clean Installation
If upgrade installations continue to fail, a clean installation may be the most effective solution.
Important
Back up all important files before proceeding.
Perform a Clean Install
- Create bootable Windows 11 installation media.
- Boot from the USB drive.
- Select Custom Installation.
- Delete existing Windows partitions if appropriate.
- Install Windows on unallocated space.
- Follow the setup instructions.
A clean installation removes corrupted upgrade files and configuration issues that may be preventing successful installation.
For persistent installation failures, this method often delivers the best results.
Conclusion
A Windows 11 installation that becomes stuck can result from hardware problems, damaged installation files, insufficient storage, firmware issues, or software conflicts. While the situation may appear serious, most installation freezes can be resolved with systematic troubleshooting.
Start by waiting to ensure Windows is not still processing tasks in the background. Then disconnect unnecessary devices, verify available storage, recreate installation media, and check hardware health. If needed, use Startup Repair, update your BIOS, or perform a clean installation to eliminate underlying problems.
By following these eight proven fixes, you can overcome most Windows 11 installation issues and complete the setup successfully.
Frequently Asked Questions
How long should a Windows 11 installation take?
Most installations finish within 20 to 60 minutes, although older systems and large feature updates may take longer.
Is it safe to restart a stuck Windows 11 installation?
If there has been no progress or disk activity for several hours, restarting may be necessary. However, interrupting an active installation can sometimes cause additional issues.
Why is Windows 11 stuck at a certain percentage?
Common causes include corrupted installation files, insufficient storage, hardware conflicts, faulty RAM, or update-related problems.
Can a bad SSD or hard drive cause installation freezes?
