No Bootable Devices Found Dell Laptop Error on Startup

Hey there,

Today I was working on my laptop, suddenly I got this unexpected error message during startup, “No bootable devices found.” I’m not entirely sure what triggered it this error or behaviour. I didn’t make any recent changes to my laptop, so this issue seems to have come out of the blue.

One of my friend suggested me to restart the laptop which I did several times, hoping it would resolve the issue, but the same error message repeated.

Now, I don’t know how to proceed further as my technical knowledge is very low so I am seeking help from this community.
