Fix There Is Not Enough Free Disk Space to Complete the System BIOS and Device Firmware Update Operation
The “There Is Not Enough Free Disk Space to Complete the System BIOS and Device Firmware Update Operation” error usually appears when Windows or your computer manufacturer’s update utility attempts to install a BIOS or firmware update but cannot find enough available storage. BIOS and firmware updates often require temporary working space on the system drive to extract update files, create backups, and complete the installation process. If the required free space is unavailable, the update is cancelled to prevent an incomplete firmware installation.
This error commonly occurs on computers with nearly full system drives, especially devices with smaller SSDs such as 64 GB or 128 GB models. It may also appear if temporary files consume excessive storage or if the recovery partition lacks sufficient space. Fortunately, the issue can usually be resolved by freeing disk space, cleaning temporary files, extending the system partition, or installing the update after performing basic maintenance.
This guide explains the best methods to fix the “There Is Not Enough Free Disk Space to Complete the System BIOS and Device Firmware Update Operation” error in Windows 11 and Windows 10.
What Causes This Error?
A BIOS or firmware update requires temporary storage while Windows prepares and verifies the update package. If the required storage is unavailable, the update cannot proceed.
Common causes include:
- Low free space on the system drive
- Large temporary files
- Full Downloads folder
- Windows Update cache consuming storage
- Insufficient recovery partition space
- Hibernation and page files using excessive storage
- Previous BIOS update files not removed
- Corrupted Windows Update cache
- Disk errors
- Small-capacity SSD
Method 1: Free Up Space on the System Drive
The first step is to ensure that your Windows drive has enough available storage. While the exact requirement varies by manufacturer, having at least 10–20 GB of free space is generally recommended before installing BIOS or firmware updates.
Deleting unnecessary files often resolves the issue immediately.
Follow these steps:
- Open File Explorer.
- Click This PC.
- Check the available space on the C: drive.
- Delete unnecessary files.
- Empty the Recycle Bin.
- Remove large downloads you no longer need.
- Restart the computer.
- Try the BIOS update again.
If sufficient free space is available, the update should proceed normally.
Method 2: Run Storage Sense
Windows Storage Sense automatically removes temporary files, cached data, and other unnecessary items that occupy valuable disk space.
Using Storage Sense is a safe way to recover storage without affecting your personal files.
Follow these steps:
- Press Windows + I to open Settings.
- Click System.
- Select Storage.
- Turn on Storage Sense if it is disabled.
- Click Storage Sense.
- Select Run Storage Sense now.
- Wait for Windows to finish cleaning.
- Restart the computer.
Check the available disk space before attempting the update again.
Method 3: Use Disk Cleanup
Disk Cleanup removes Windows Update leftovers, temporary internet files, delivery optimization files, and other unnecessary data.
This built-in tool can free several gigabytes of storage on systems that have not been cleaned recently.
Follow these steps:
- Press Windows + S.
- Search for Disk Cleanup.
- Open the application.
- Select the C: drive.
- Click Clean up system files.
- Select items such as:
- Windows Update Cleanup
- Temporary Files
- Delivery Optimization Files
- Temporary Internet Files
- Recycle Bin
- Click OK.
- Confirm the cleanup.
- Restart the computer.
Try installing the firmware update again.
Method 4: Remove Temporary Files
Temporary files created by Windows and applications can consume a significant amount of storage over time.
Deleting these files manually may free enough space for the firmware update.
Follow these steps:
- Press Windows + R.
- Type:
%temp%- Press Enter.
- Select all files.
- Delete them.
- Repeat the process using:
temp- Also open:
prefetch- Delete removable files.
- Restart Windows.
Ignore any files currently in use.
Method 5: Uninstall Unused Applications
Large applications and games may occupy tens or even hundreds of gigabytes of storage.
Removing software you no longer use can quickly free enough space for BIOS updates.
Follow these steps:
- Open Settings.
- Go to Apps.
- Click Installed apps.
- Sort by Size.
- Select unnecessary applications.
- Click Uninstall.
- Follow the prompts.
- Restart the computer.
Check the available storage afterward.
Method 6: Clear the Windows Update Cache
Corrupted or incomplete Windows Update files may occupy storage and interfere with firmware updates.
Clearing the update cache forces Windows to recreate fresh update files.
Follow these steps:
- Open Command Prompt as Administrator.
- Run:
net stop wuauserv- Run:
net stop bits- Open:
C:\Windows\SoftwareDistribution- Delete its contents.
- Return to Command Prompt.
- Run:
net start wuauserv- Run:
net start bits- Restart the computer.
Attempt the firmware update again.
Method 7: Check the Disk for Errors
File system corruption may prevent Windows from calculating or using available storage correctly.
Running Check Disk repairs logical file system errors before attempting another BIOS update.
Follow these steps:
- Open Command Prompt as Administrator.
- Run:
chkdsk C: /f- Press Enter.
- Type Y if prompted.
- Restart the computer.
- Allow the scan to complete.
- Sign back into Windows.
Retry the firmware update.
Method 8: Download the BIOS Update Manually
Instead of using Windows Update, many manufacturers provide standalone BIOS update utilities that may require less temporary storage.
Installing the update directly from the manufacturer can bypass certain Windows update limitations.
Follow these steps:
- Visit your computer manufacturer’s support website.
- Search for your exact model.
- Download the latest BIOS or firmware update.
- Read the installation instructions carefully.
- Close all running applications.
- Connect the laptop to AC power if applicable.
- Run the update utility.
- Allow the update to complete without interruption.
Do not turn off the computer during the BIOS update.
Method 9: Extend the System Partition or Upgrade the Storage Drive
If your system drive is nearly full all the time, especially on devices with 64 GB or 128 GB SSDs, you may need to increase available storage.
Expanding the system partition or replacing the storage drive provides a permanent solution for future Windows and firmware updates.
Follow these steps:
- Open Disk Management.
- Check available partition space.
- Extend the system partition if unallocated space exists.
- Alternatively, replace the SSD with a larger drive.
- Reinstall or clone Windows if necessary.
- Verify that sufficient free space is available.
- Retry the BIOS update.
Maintaining adequate free storage also improves overall system performance.
Conclusion
The “There Is Not Enough Free Disk Space to Complete the System BIOS and Device Firmware Update Operation” error usually occurs because Windows does not have enough available storage to prepare and install a BIOS or firmware update. In most cases, freeing space on the system drive by removing temporary files, uninstalling unused applications, running Storage Sense, or using Disk Cleanup is enough to resolve the issue. Clearing the Windows Update cache and checking the disk for file system errors can also eliminate software-related problems that interfere with the update process. If storage remains consistently low, upgrading to a larger SSD or expanding the system partition provides a long-term solution. Once sufficient free space is available, the BIOS or firmware update should install successfully.
