It sounds like the POST delay of your laptop is currently set to zero second
and the machine is trying to boot from the wrong devise.
Try hitting the [ESC] key repeatedly as soon as you turn on the computer.
This key sequence could be different (mine was HP Probook) - so check the support page for your laptop model.
The hitting motion must be a very quick tapping, not a long pressing.
If you miss the timimg, simply start over.
This should let you enter the BIOS menu where you can select the correct booting device.
