Laptop USB Startup Key not detected at boot

4.5

The laptop asks for the USB key but doesn't see it when plugged in.

Symptoms
  • "Insert USB key"
  • Boot hang
  • No activity light
Possible Causes
  • USB 3.0 port (use 2.0)
  • BIOS setting
  • Corrupt key file

Step-by-Step Fix

1

Use USB 2.0 Port

Some BIOS versions can't read USB 3.0/3.1 ports at boot.

2

Enable Legacy USB

Ensure the BIOS can see USB drives before the OS loads.

3

Check for .BEK file

Ensure the hidden .BEK file is in the root of the USB drive.

When to See a Technician

Try a different USB port, preferably one that is directly connected to the motherboard (not a hub).
