@muhammadzain check your BIOS to see if your computer recognizes a boot drive.
Enter BIOS during power on (before Windows loads)
# Power on the system by pressing the power button.
# Repeatedly tap the F1 key when the Lenovo, ThinkPad, ThinkStation, or ThinkCentre logo appears, The computer may beep once to indicate that it will boot to BIOS.
Let us know if your BIOS recognizes a boot device. This could easily be a bad HDD/SSD
