What does No bootable device mean on my laptop?
“No bootable device” means the computer can't find the drive that Windows is on. Either the drive has failed, it's come loose, or the start-up settings have changed.
Treat this as urgent. Stop using it the way it is and get it to a technician as soon as you can.

What usually causes it
- Hard drive or SSD failing or not detected
- Drive connector loose after a drop
- Start-up (BIOS) settings changed after a flat CMOS battery
Most likely first. A hands-on test confirms which one it is.

Please don't
- Don't keep restarting it. A failing drive gets worse each time
