The "No Media (0 bytes)" error in BIOS when using Rufus to create an Arch Linux bootable USB is typically caused by the drive being locked, a corrupted partition table, or a compatibility issue with the specific flash controller. This prevents the system from recognizing the storage capacity, making booting impossible until the device is properly initialized and written with the correct image format.
Understanding the Root Cause
When Rufus writes an ISO image to a USB drive, it modifies the partition table and file system structures. Some USB flash drives, particularly those from less common manufacturers like Chips Bank, have controllers that are sensitive to these changes. If the drive was previously formatted in a way that conflicts with the new structure, or if the write process was interrupted, the controller may enter a protective state where it reports zero capacity. This is not necessarily a hardware failure but rather a logical lock that requires specific tools to reset. The BIOS sees the USB device as present but unable to read any sectors, hence the 0-byte report.
Step-by-Step Solution
To resolve this issue, you must first ensure the drive is completely cleared of any previous partitions. Follow these steps carefully:
- Check Drive Health: Before attempting any fixes, verify that the USB drive is physically functional. Try connecting it to another computer to see if it is detected there. If it shows up normally on another machine, the issue is likely software-related on your current setup.
- Use DiskPart for Cleaning: On Windows, open Command Prompt as Administrator. Run
diskpart, then List Disk to identify your USB drive number. Be extremely careful to select the correct disk, as this process will erase all data. Select the disk using Select Disk X (replace X with your drive number), then run Clean. This command removes all partition information.
- Create a New Partition: After cleaning, create a primary partition by running
Create Partition Primary. Format it quickly with FAT32 using Format FS=FAT32 Quick, and assign a drive letter with Assign.
- Rewrite with Rufus: Now, use Rufus again. In the Rufus interface, ensure you are writing the Arch Linux ISO. For better compatibility with older BIOS systems, try selecting "DD Image" mode instead of the default "ISO Image" mode if available. DD mode writes the image byte-for-byte, which can bypass certain partition table issues.
If the above steps do not work, consider checking for firmware updates for your USB drive, although this is rare for consumer-grade devices. Additionally, ensure that your BIOS settings are configured to allow booting from USB devices. Disable Secure Boot temporarily to rule out signature verification issues, although Arch Linux images are generally compatible.
Alternative Tools and Methods
Sometimes Rufus may struggle with specific USB controllers. Using alternative tools can help bypass these compatibility issues. Tools like Etcher or Ventoy offer different approaches to writing bootable drives. Ventoy, in particular, allows you to simply copy ISO files onto the drive without reformatting each time, which can be more resilient against partition table errors. If you choose to use Etcher, ensure you have the latest version installed, as older versions may have bugs related to large ISO files.
Another approach is to use the Linux terminal directly if you have access to a Linux environment. Commands like
dd can write the ISO image directly to the device. For example,
sudo dd if=archlinux.iso of=/dev/sdX bs=4M status=progress (replace /dev/sdX with your actual device path). This method is straightforward and often succeeds where GUI tools fail because it operates at a lower level. However, be cautious with the
dd command, as selecting the wrong destination device can lead to data loss on your hard drive.
For users who frequently install various Linux distributions, creating a multi-boot USB with Ventoy might be the most efficient long-term solution. It reduces the need to repeatedly clean and rewrite drives, minimizing the risk of encountering the "No Media" error during the installation process.

Preventing Future Issues
To avoid this problem in the future, always safely eject USB drives after use. Improper removal can leave the file system in an inconsistent state, leading to recognition issues. Regularly update your BIOS to ensure compatibility with newer USB standards and controllers. If you continue to experience issues with a specific USB drive, it may be defective and should be replaced. High-quality drives from reputable manufacturers tend to have more robust controllers that handle partition changes more gracefully.
Frequently Asked Questions
Why does my USB drive show 0 bytes in Disk Management?
This usually indicates that the partition table is corrupted or missing. The operating system can see the device but cannot read any storage sectors. Running the
Clean command in DiskPart often resolves this by resetting the drive's logical structure.
Can I recover data from a USB drive showing No Media?
Data recovery is difficult when the drive reports zero media because the file system structure is inaccessible. Professional data recovery services may be able to retrieve data by bypassing the controller, but standard software tools will likely fail. It is best to assume the data is lost and focus on fixing the drive.
Is it safe to use DD mode in Rufus?
Yes, DD mode is safe and often more reliable for creating bootable drives. It writes the image exactly as it exists in the ISO file, without modifying partition tables. This can prevent compatibility issues with certain USB controllers that expect a specific layout.
What should I do if Rufus fails to start?
Ensure you are running Rufus as an administrator. Also, check if your antivirus software is blocking Rufus from accessing raw disk devices. Disabling real-time protection temporarily or adding an exception for Rufus can resolve permission issues.
Does Secure Boot affect USB booting?
Secure Boot can prevent unsigned bootloaders from running. While many modern Linux distributions include signed bootloaders, some older or custom setups may fail. Disabling Secure Boot in the BIOS is a common troubleshooting step for boot failures.
