Introduction
The "Remove Disk or Other Media" error is a common startup problem that appears before Windows begins loading. Instead of booting into the operating system, the computer displays a message asking you to remove a disk or other removable media and press a key to restart.
This error usually occurs because the computer is trying to boot from the wrong device, such as a USB flash drive, memory card, external hard drive, or an incorrectly configured storage device.
Fortunately, the issue is often easy to resolve by checking the connected devices, correcting the BIOS boot order, or repairing Windows boot files.
This guide explains the causes of the error and provides step-by-step solutions to help you restore normal system startup.
What Does "Remove Disk or Other Media" Mean?
This error indicates that the computer cannot find a valid bootable operating system on the device it is attempting to start from.
Instead of loading Windows, the BIOS or UEFI firmware stops the boot process and displays the error message.
The problem usually occurs before Windows itself begins loading.
Common Causes of the Error
Several situations can trigger this startup error.
Bootable USB Drive Connected
If a USB flash drive is connected and is not properly bootable, the computer may attempt to start from it instead of the internal drive.
Incorrect Boot Order
The BIOS or UEFI boot priority may be configured to check removable devices before the Windows drive.
Damaged Boot Files
Corrupted Windows boot files can prevent the operating system from loading correctly.
Faulty Storage Device
A failing SSD or HDD may not be detected properly during startup.
External Storage Devices
Memory cards, external hard drives, DVDs, or USB devices connected during startup can interfere with the boot process.
Step 1: Remove All External Storage Devices
Before making any system changes:
Disconnect:
USB flash drives
External hard drives
Memory cards
DVDs or CDs
USB card readers
After removing them:
Restart the computer.
Check whether Windows starts normally.
This simple step resolves the problem in many cases.
Step 2: Check the Boot Order in BIOS
If the error continues, verify the boot sequence.
Enter BIOS or UEFI
Restart the computer and press the appropriate BIOS key.
Common keys include:
Delete (Del)
F2
F10
Esc
The correct key depends on your computer or motherboard manufacturer.
Verify Boot Priority
Open the Boot section.
Ensure that:
Windows Boot Manager
SSD
HDD
is listed before removable devices such as USB drives.
Save the changes and restart the computer.
Step 3: Verify That the Drive Is Detected
Inside the BIOS, check whether your storage drive appears in the storage information.
If your SSD or HDD is missing:
Check SATA or NVMe connections.
Reseat the drive if possible.
Verify power cables on desktop systems.
A drive that is not detected cannot boot Windows.
Step 4: Repair Windows Startup
If the boot order is correct but Windows still will not start, repair the boot files.
Boot From Windows Installation Media
Insert a Windows installation USB.
Boot from the USB drive.
Choose:
Repair your computer
Then open:
Startup Repair
Windows will automatically scan for startup problems and attempt to repair them.
Step 5: Rebuild the Boot Configuration
If Startup Repair does not solve the problem, you can rebuild the Windows boot configuration.
Open Command Prompt from the Windows Recovery Environment.
Run the following commands one at a time:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
Restart the computer after the commands complete.
These commands repair common Windows boot problems.
Step 6: Check the Health of Your Drive
If the error appears repeatedly, the storage device may be failing.
Warning signs include:
Slow startup
Clicking sounds from HDDs
Frequent file corruption
Random crashes
SMART warnings
If the drive is failing, back up important data as soon as possible and consider replacing it.
Step 7: Recreate the Bootable USB (If Installing Windows)
If the error occurs while installing Windows from a USB drive, the installation media itself may be damaged.
Create a new bootable USB using:
A verified Windows ISO
A reliable USB creation tool
Then try the installation again.
Common Mistakes Beginners Make
Many startup problems are caused by simple mistakes.
Examples include:
Leaving a USB drive connected
Selecting the wrong boot device
Disconnecting the system drive accidentally
Creating an incomplete bootable USB
Changing BIOS settings without understanding them
Carefully checking these issues can save significant troubleshooting time.
Best Practices to Prevent Boot Errors
To reduce the chances of future startup problems:
Remove unnecessary USB devices before restarting.
Keep BIOS settings unchanged unless required.
Create Windows recovery media.
Regularly back up important files.
Monitor the health of your storage drives.
Shut down Windows properly to avoid file corruption.
Following these practices helps maintain a reliable boot environment.
Conclusion
The "Remove Disk or Other Media" error usually indicates that the computer is attempting to boot from the wrong device or cannot locate a valid operating system. In most cases, disconnecting removable media, correcting the BIOS boot order, or repairing Windows boot files resolves the issue quickly.
If the problem continues even after these steps, inspect your storage device for hardware issues and consider creating fresh Windows installation media if you're performing a new installation.

Frequently Asked Questions
1. What causes the "Remove Disk or Other Media" error?
It is usually caused by incorrect boot order, connected removable media, damaged boot files, or storage device issues.
2. Can a USB flash drive cause this error?
Yes. If the computer tries to boot from a non-bootable USB drive, this error may appear.
3. How do I change the boot order?
Enter the BIOS or UEFI settings during startup and set your Windows drive or Windows Boot Manager as the first boot device.
4. Can corrupted Windows boot files cause this problem?
Yes. Damaged boot files can prevent Windows from starting and trigger boot-related errors.
5. Will reinstalling Windows fix this error?
If the problem is caused by corrupted system files and other repair methods fail, reinstalling Windows may resolve the issue. However, hardware problems should be ruled out first.
