This is very important.
You need to make sure that your Dell laptop is set to boot from the correct boot device. The wrong boot order can cause your computer to boot from the wrong device, thinking it is the correct boot device.

5.Make sure you are using UEFI
When I had my own challenges with this initial error, this method worked for me and I hope it works for you too.
To fix the problem, simply switch from Legacy to UEFI.
Here's how to switch to UEFI on your Dell laptop
- Boot into BIOS

It is important that you properly check your computer for loose cables. If so, you want to reconnect it correctly.
The important cable to check is the cable that is connected to your hard drive if you are trying to boot from a hard drive.
Also check the cable connected to the CD/DVD drive if you are trying to boot from a CD/DVD drive. If it is not connected, connect it.
If you want to boot from USB, make sure all USB ports are working properly.
