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.
- Power off your PC completely
- Disconnect the power cable (and battery, if removable)
- Hold the Power button for 15–20 seconds
- Reconnect power and turn the system back on
- 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 using an incorrect or incompatible BIOS file.
- Exact PC or motherboard model number
- Correct operating system (if required by the vendor)
- BIOS revision recommended for recovery
- Visit your PC or motherboard manufacturer’s official support website
- Enter your exact model number
- Download the latest BIOS version or the BIOS recovery file specifically listed for your device
- Do not rename the file unless the manufacturer explicitly instructs you to do so
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.
- Right-click the downloaded BIOS file
- Select Extract All
- Open the extracted folder
- Locate the BIOS file (usually
.BIN,.CAP,.ROM, or.FD) - 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.
How to prepare the USB drive:
- Use a USB drive with 8–32 GB capacity (older USB 2.0 drives work best)
- Connect it to a working PC
- Open This PC
- Right-click the USB drive and select Format
- Set:
- File system: FAT32
- Allocation unit size: Default
- Click Start and wait for formatting to finish
After formatting:
- Copy the BIOS recovery file directly to the root directory of the USB drive
- Do not place it inside any folder
5. Rename the BIOS File (If Required by Manufacturer)
Some manufacturers require the BIOS file to have a specific name for recovery mode to detect it.
- Check the official support documentation for your PC model
- 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.
Common key combinations (varies by manufacturer):
- Ctrl + Esc
- Win + B
- Win + V
- Fn + R
- Turn off the PC
- Insert the prepared USB drive
- Press and hold the required key combination
- Press the Power button while holding the keys
- Release keys only when recovery starts
If the wrong key combination is used, the system will fail to locate recovery files.
7. Try a Different USB Port
Some systems can only read BIOS recovery files from specific USB ports.
- Use a rear USB port (for desktops)
- Avoid USB hubs or front-panel ports
- 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.
- Enter BIOS/UEFI settings
- Disable Secure Boot
- Disable Fast Boot
- Save changes and exit
- 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.
- Delete the previously downloaded BIOS file
- Re-download it from the official website
- Verify file size matches what the manufacturer lists
- 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.
