Have you made any changes on the laptop prior to the issue?
I would suggest you to Disable secure boot and enable Legacy Boot mode.
Please follow the steps provided to disable secure boot:
a. Completely shut down the laptop.
b. Power on the system. As soon as the first logo screen appears, immediately press Delete to enter the BIOS.
c. Use the right arrow key to select Authentication.
d. With Secure Boot highlighted, press Enter and then the down arrow to select Disabled.
e. Use the right arrow key to select Boot Options.
f. With Launch CSM highlighted, press Enter and use the down arrow to select Always.
g. Press Enter.
h. Press the F10 key to save changes and restart the system.
