The "No Media" error on a Chips Bank flash disk usually occurs because Rufus fails to write the correct partition table or the USB controller is incompatible with standard ISO modes. To resolve this, switch Rufus to DD Image mode instead of ISO Image mode, which forces a raw byte-for-byte copy that bypasses complex partitioning logic and ensures the BIOS detects the drive as bootable media immediately.
Understanding the Hardware Limitation
Chips Bank is a common manufacturer of budget USB flash drives, often using controllers from companies like SMI (Silicon Motion) or Phison. These controllers sometimes struggle with the standard Windows NTFS or FAT32 partition structures that Rufus creates by default when writing an ISO image. The operating system sees the device, but the bootloader cannot find the expected file structure, resulting in a zero-byte detection or a complete failure to boot. This is not a hardware defect but rather a compatibility issue between the drive's firmware and the installation method.
When you encounter the "No Media" message during the Arch Linux installation process, it means the UEFI or Legacy BIOS interface cannot enumerate the storage device properly. This often happens because the drive’s capacity is misreported or because the partition table type (GPT vs MBR) conflicts with the motherboard’s expectations. Using the default ISO mode in Rufus attempts to create a hybrid EFI/MBR structure that some older or cheaper USB controllers cannot parse correctly.
Chips, Bank, Flash Disk: No Media (0 bytes) Installing Arch Linux with Rufus provides additional context on why specific drive models fail under standard conditions. Understanding that this is a software-handling issue rather than a broken stick is crucial for troubleshooting.
Switching to DD Image Mode
The most effective solution is to use Rufus's DD Image mode. Unlike ISO mode, which tries to make the USB drive look like a CD-ROM drive with a filesystem, DD mode writes the binary data directly to the sectors of the USB stick. This creates a raw clone of the Arch Linux installation media, which is universally recognized by BIOS and UEFI systems regardless of the USB controller brand.
To perform this action, first download the latest Arch Linux ISO from the official website. Open Rufus and select your Chips Bank flash drive from the device dropdown menu. Ensure that the partition scheme is set to
MBR for BIOS or UEFI-CSM targets, or
GPT if you are targeting pure UEFI systems, though MBR is generally safer for older hardware.
Select the Arch Linux ISO file. Crucially, before clicking Start, Rufus will ask how to write the disk. You must choose
DD Image instead of
ISO Image. This option may be hidden behind a small dropdown arrow next to the Start button in newer versions of Rufus. Confirm any warnings about data destruction, as this process will erase the entire contents of the USB drive.
Once the process completes, do not eject the drive immediately. Wait for the "Ready" notification. Test the drive on the target machine by selecting it from the boot menu. If the system still fails to detect media, proceed to the next step regarding formatting and low-level checks.
Verifying Drive Integrity and Formatting
If DD mode does not resolve the issue, the problem may lie in the drive’s existing partition table or file system corruption. Some Chips Bank drives come pre-formatted with unusual cluster sizes or hidden partitions that confuse the bootloader. It is advisable to completely wipe the drive before rewriting it.
Use the Windows Disk Management tool or a utility like
diskpart to clean the drive. Open Command Prompt as Administrator and enter the following commands sequentially:
diskpart
list disk
select disk X (replace X with your USB drive number)
clean
create partition primary
format fs=fat32 quick
assign
exit
This sequence removes all partition information and creates a fresh FAT32 partition. Afterward, repeat the Rufus DD mode procedure. The clean slate ensures that no residual metadata interferes with the new Arch Linux boot sector. Additionally, verify that the USB port you are using is functional by testing another device. Avoid USB 3.0 ports if your motherboard has known issues with USB enumeration during early boot stages, as mentioned in similar troubleshooting guides.

Alternative Tools and Final Checks
If Rufus continues to fail, consider using alternative tools such as BalenaEtcher or the official Arch Linux installation instructions using
dd on Linux or macOS. BalenaEtcher also defaults to a raw write mode that is highly compatible with problematic USB controllers. On a Linux system, you can achieve the same result using the terminal command
sudo dd if=archlinux.iso of=/dev/sdX bs=4M status=progress oflag=sync, replacing
/dev/sdX with your actual device identifier.
Ensure that Secure Boot is disabled in the BIOS settings, as Arch Linux installers may not have the necessary keys signed for strict Secure Boot environments. Also, check that Fast Boot is turned off, as this feature can skip USB initialization routines required for detecting external media.
Frequently Asked Questions
Why does my USB drive show 0 bytes after using Rufus?
This indicates that the partition table was written incorrectly or the USB controller failed to initialize the file system. Switching to DD Image mode in Rufus fixes this by writing raw data that the BIOS can read without relying on complex filesystem structures.
Can I use GParted to fix the Chips Bank drive?
Yes, GParted can be used to delete existing partitions and create a new FAT32 partition, but it cannot write the Arch Linux ISO directly. You must use Rufus or dd to write the installer image after preparing the drive with GParted.
Is it safe to use DD mode on my USB drive?
It is safe for the hardware, but it will permanently erase all data on the drive. Always back up important files before proceeding, as the DD method overwrites the entire disk sector by sector without preserving existing content.
What should I do if the BIOS still doesn't see the drive?
Try a different USB port, preferably a USB 2.0 port if available, as they are more stable for boot media. Disable Fast Boot and Secure Boot in the BIOS, and ensure the drive is selected as the first boot priority in the boot order menu.
Does the size of the USB drive matter for Arch Linux?
Arch Linux requires very little space, typically under 500 MB for the base system. Any USB drive with at least 2 GB of capacity is sufficient, but smaller drives may have slower write speeds or compatibility issues with certain controllers.
