You press the power button, expecting the familiar Windows logo to greet you — but instead, you see a black screen with a cold message: “No Bootable Device.” It’s one of those heart-sinking moments for any PC user. The good news? In most cases, this error can be fixed without replacing your entire laptop or desktop.
Here’s a
step-by-step guide to understand the cause and apply the right solution.
1. Check Your Boot Order in BIOS/UEFI
Sometimes,
your system forgets where Windows is installed, especially after a BIOS reset
or hardware change.
- Turn off your PC.
- Turn it back on and press
the BIOS key (usually F2, F10, Del, or Esc).
- Look for the “Boot Order” or
“Boot Priority” menu.
- Make sure your main hard
drive or SSD with Windows installed is listed first.
2. Reseat Your Storage Drive
If you’re
comfortable opening your device, try reseating the SSD or HDD. A loose
connection can make the system think there’s no bootable device. If you’re not
confident, ask a technician to help.
3. Repair the Master Boot Record (MBR)
Corrupted
boot records can cause this error.
- Boot from a Windows
installation USB or DVD.
- Select “Repair your
computer” → “Troubleshoot” → “Advanced options” → “Command Prompt.”
- Type these commands,
pressing Enter after each:
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
4. Check for Drive Failure
If none
of the above works, your drive may be failing.
- Boot from a diagnostic tool
(many brands provide them for free).
- If the drive shows errors,
consider replacing it and reinstalling Windows.
The “No Bootable Device” error can range from a simple BIOS setting issue to a failing hard drive. The key is to start with the easiest checks before moving on to advanced repairs. With a bit of patience, you might just save yourself from unnecessary expenses.
