The BIOS (Basic Input/Output System) is a critical firmware component that allows your computer to initialize hardware and boot into Windows. During a BIOS update or recovery process, some users encounter an alarming error stating that “BIOS recovery files cannot be found or the files are corrupted.” When this happens, the system may fail to boot properly, remain stuck in a recovery loop, or refuse to complete the BIOS recovery process.
Although this error sounds serious, it does not necessarily mean your motherboard is damaged. In most cases, the problem is caused by missing recovery files, an incorrect BIOS version, corrupted USB media, or improper recovery steps. In this guide, we will walk you through all the effective ways to fix the BIOS recovery files cannot be found or the files are corrupted error on Windows PCs and laptops.
Fix BIOS Recovery Files Cannot Be Found or the Files Are Corrupted
Follow the troubleshooting methods below carefully and in order. Some steps may vary slightly depending on your PC manufacturer, but the general principles remain the same.
1. Restart the System and Retry BIOS Recovery
Before attempting advanced fixes, start with a simple restart. Temporary firmware glitches can sometimes interrupt the recovery process. A quick reboot refreshes the system environment, clears minor errors, and gives the firmware a clean chance to reload essential processes properly.
1. Power off your PC completely.
2. Disconnect the power cable (and battery, if removable) and hold the Power button for 15-20 seconds.
3. Reconnect power and turn the system back on.
4. Retry the BIOS recovery process.
If the error persists, proceed to the next steps.
2. Download the Correct BIOS Version for Your Exact Model
One of the most common causes of this error is the use of an incorrect or incompatible BIOS file. To avoid this issue, it is important to ensure that you have the exact PC or motherboard model number, the correct operating system if it is required by the manufacturer, and the specific BIOS revision that is recommended for recovery.
1. Visit your PC or motherboard manufacturer’s official support website.
2. Enter your exact model number.
3. Download the latest BIOS version or the BIOS recovery file specifically listed for. your device
4. Do not rename the file unless the manufacturer explicitly instructs you to do so.
5. Using the wrong BIOS file will always result in a recovery failure.
3. Extract the BIOS File Properly
Many BIOS recovery files are provided as ZIP archives. If they are not extracted correctly, the recovery process will fail. Ensure you properly unzip the contents using a reliable extraction tool so that all required files are placed in the correct format and directory.
Incomplete or incorrect extraction can prevent the system from recognizing the recovery file during the process.
1. Right-click the downloaded BIOS file and select Extract All.
2. Open the extracted folder and locate the BIOS file (usually .BIN, .CAP, .ROM, or .FD)
3. Make sure the file is not nested inside multiple folders
Only the actual BIOS file, not the ZIP file, should be used for recovery.
4. Prepare the USB Drive Correctly
An improperly formatted USB drive is another major reason BIOS recovery files are not detected. If the file system on the USB drive is not compatible with your system’s BIOS requirements, the recovery process may fail to recognize the necessary files.
To prepare the USB drive:
1. Use a USB drive with 8-32 GB capacity (older USB 2.0 drives work best)
2. Connect it to a working PC.
3. Open This PC, right-click the USB drive and select Format.
4. Next, set the file system to FAT32, as this format is widely supported for BIOS recovery and ensures the system can properly detect the files. You should also leave the allocation unit size set to Default
5. Click Start and wait for formatting to finish.
After formatting the USB drive, copy the BIOS recovery file directly to the root directory of the drive so that the system can easily detect it during the recovery process. Make sure you do not place the file inside any folder, as doing so may prevent the BIOS from locating and reading the recovery file properly.
5. Rename the BIOS File
Some manufacturers require the BIOS file to have a specific name for recovery mode to detect it.
1. Check the official support documentation for your PC model
2. Rename the file exactly as instructed (case-sensitive in some cases)
For example:
BIOS.binAMIBOOT.ROMHPBIOS.BIN
If renaming is required and done incorrectly, the BIOS recovery tool will not find the file.
6. Use the Correct BIOS Recovery Key Combination
Most systems require a specific key combination to trigger BIOS recovery mode. If the correct keys are not pressed at the right time, the system may boot normally instead of entering recovery. Refer to your device’s documentation and ensure the key sequence is held or pressed exactly as instructed during startup.
1. Turn off your PC completely before starting the recovery process.
2. Insert the prepared USB drive containing the BIOS recovery file into your computer.
3. Press and hold the required key combination (such as Ctrl + Esc, Win + B, Win + V, or Fn + R).
4. While holding the keys, press the Power button to turn on the system.
5. Keep holding the keys until the recovery process starts, then release them once you see the recovery screen.
7. Try a Different USB Port
Some systems can only read BIOS recovery files from specific USB ports. Using the wrong port may prevent the system from detecting the recovery media altogether. For best results, connect the USB drive to a primary port, often a USB 2.0 port directly on the motherboard, as these are more consistently supported during the recovery phase.
1. Use a rear USB port (for desktops)
2. Avoid USB hubs or front-panel ports
3. Try multiple USB ports one at a time
This simple step often resolves detection issues.
8. Disable Secure Boot and Fast Boot (If Accessible)
If you can still access BIOS settings partially, disabling certain options can help.
1. Enter BIOS/UEFI settings
2. Disable Secure Boot
3. Disable Fast Boot
4. Save changes and exit
5. Retry BIOS recovery
These features can sometimes block recovery utilities from accessing USB devices.
9. Re-download the BIOS File
If the BIOS file itself is corrupted, recovery will always fail. Even if the process starts, it may stop midway or the system may not recognize the file at all. Always download the BIOS file from the official manufacturer website and verify its integrity to ensure a successful recovery.
1. Delete the previously downloaded BIOS file
2. Re-download it from the official website
3. Verify file size matches what the manufacturer lists
4. Prepare the USB drive again from scratch
Never use BIOS files from third-party sources.
Wrapping Up
With that, we wrap up our comprehensive guide on fixing the “BIOS recovery files cannot be found or the files are corrupted” error. While this issue can be intimidating, especially when your system refuses to boot, it is most often caused by incorrect BIOS files, improperly prepared USB drives, or recovery steps not being followed exactly.
By carefully matching the correct BIOS version to your device, formatting the USB drive properly, and using the correct recovery method, you can successfully restore the BIOS and bring your system back to life.
