Hello friends! 👋
Have you ever turned on your computer and instead of Windows starting normally, you saw a black screen displaying the message:
"Remove disks or other media. Press any key to restart."
At first, this error can be alarming. Many users think their hard drive has failed or that Windows has been permanently damaged. Fortunately, that's usually not the case.
This message simply means that your computer is trying to boot from a device that doesn't contain a bootable operating system. It could be a USB flash drive, DVD, external hard drive, memory card, or even an incorrect boot order in the BIOS.
The good news is that this error is often easy to fix once you understand why it appears. In this guide, you'll learn the most common causes, step-by-step solutions, and best practices to prevent the problem in the future.
💡 My Experience
I've seen this error many times while installing Windows in computer labs and repairing desktop PCs. Surprisingly, the Windows installation itself was rarely the problem.
One common situation was that a bootable USB drive was left connected after Windows installation. When the computer restarted, it attempted to boot from the USB again instead of the internal SSD.
Another frequent cause was an incorrect BIOS boot order after resetting BIOS settings or replacing storage hardware. Simply selecting the correct boot device solved the problem in just a few minutes.
That's why I always recommend checking the boot sequence before assuming Windows is corrupted.
What Does This Error Mean?
The error appears when your computer cannot find a valid bootable operating system.
Instead of loading Windows from your SSD or hard drive, the BIOS or UEFI firmware attempts to start from another device that isn't bootable.
As a result, the system displays:
Remove disks or other media.
Press any key to restart.
Why Does This Error Occur?
Common reasons include:
A bootable USB drive is still connected.
A DVD or CD is left in the optical drive.
Incorrect BIOS or UEFI boot order.
Corrupted boot files.
Damaged Windows Boot Manager.
Failed SSD or hard drive.
Incorrect boot mode (UEFI vs Legacy).
Recently cloned or replaced storage drive.
External storage device connected during startup.
Before You Start
Before making changes:
Turn off the computer completely.
Disconnect unnecessary external devices.
Keep the laptop plugged into power.
If possible, back up important files before attempting advanced repairs.
Step 1: Remove External Storage Devices
Disconnect all removable media, including:
USB flash drives
External hard drives
Memory cards
DVDs or CDs
Bootable installation media
Restart the computer.
In many cases, Windows starts normally after removing the unwanted boot device.
💡 My Recommendation
Whenever you finish installing Windows from a USB drive, remove the USB before the first normal restart. This prevents the computer from trying to boot from the installer again.
Step 2: Check the BIOS Boot Order
Restart the computer.
Enter the BIOS or UEFI setup by pressing the appropriate key during startup (commonly F2, Delete, Esc, or another key depending on your computer manufacturer).
Locate the Boot section.
Verify that your Windows SSD or hard drive is listed before removable devices.
Save the changes and restart.
Step 3: Verify That the Drive Is Detected
Inside the BIOS:
Check whether your:
SSD
NVMe drive
Hard drive
appears in the storage list.
If the drive isn't detected:
Check the physical connection (desktop PCs).
Reseat the drive if appropriate.
Consider testing the drive in another system if hardware failure is suspected.
Step 4: Check Boot Mode
Modern Windows installations generally use:
UEFI
Older installations may use:
Legacy (CSM)
If Windows was installed in UEFI mode but BIOS is currently configured for Legacy mode (or vice versa), the system may fail to boot.
Restore the correct boot mode for your Windows installation.
⚠️ Note
Changing between UEFI and Legacy modes without understanding how Windows was originally installed can prevent the operating system from booting. Make changes carefully and only if necessary.
Step 5: Repair Windows Startup
If Windows still doesn't boot:
Start the computer using a Windows installation USB.
Choose:
Repair your computer
Then open:
Startup Repair
Allow Windows to scan and repair startup problems automatically.
Step 6: Repair the Boot Files
If automatic repair doesn't solve the issue:
Open Command Prompt from the Windows Recovery Environment.
Common boot repair tools include:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
Run only the commands appropriate for your Windows installation and recovery scenario.
Step 7: Check Drive Health
If the drive is detected but Windows still won't start:
Check the storage device for:
Bad sectors
SMART warnings
File system corruption
A failing drive can prevent Windows from booting correctly.
Step 8: Disconnect Additional Drives
If multiple storage devices are installed:
Temporarily disconnect secondary drives (where practical) and leave only the Windows drive connected.
This helps identify whether the system is attempting to boot from the wrong storage device.
Step 9: Restore BIOS Defaults
If BIOS settings were recently changed:
Load the default BIOS settings.
Save and restart.
Sometimes incorrect firmware settings prevent Windows Boot Manager from loading properly.
Step 10: Reinstall Windows (Last Resort)
If:
Boot repair fails,
The drive is healthy,
Windows files are severely damaged,
a clean Windows installation may be necessary.
Back up important data first whenever possible.
Common Causes and Solutions
| Problem | Solution |
|---|---|
| USB drive connected | Remove the USB |
| Wrong boot order | Select the Windows drive first |
| Boot Manager damaged | Repair startup files |
| Incorrect BIOS mode | Use the correct boot mode |
| SSD not detected | Check hardware connections |
| Corrupted Windows | Run Startup Repair |
| Drive failure | Test or replace the storage device |
How to Prevent This Error
Follow these best practices:
Remove bootable USB drives after installation.
Avoid changing BIOS settings unnecessarily.
Keep Windows updated.
Shut down Windows properly.
Monitor SSD or HDD health regularly.
Back up important files.
💡 Pro Tip
After successfully installing Windows, enter the BIOS once and verify that Windows Boot Manager (or your system drive) is the first boot option. This simple check can prevent many future boot-related errors.

Interesting Facts
This error usually occurs before Windows begins loading.
Many boot issues are caused by incorrect firmware settings rather than damaged operating system files.
Modern computers typically use UEFI instead of traditional BIOS.
Windows Boot Manager controls the startup process on most modern Windows systems.
A simple USB flash drive left connected can sometimes trigger this error.
Best Practices
Keep only necessary boot devices connected.
Update BIOS only when recommended by the manufacturer.
Use high-quality USB drives for Windows installation.
Create regular system backups.
Check your storage drive's health periodically.
