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.

If you want your computer to boot from the correct boot device, you must make your boot device the first device in the boot order.

For example,

If you want to allow your Dell laptop to boot from a bootable USB device, please go to the boot order in BIOS and adjust the boot order to rank the bootable USB device first.

To fix the problem, simply switch from Legacy to UEFI.

Here's how to switch to UEFI on your Dell laptop

1. Boot into BIOS
2. Since there are many different BIOS versions, I recommend reading your motherboard manual and seeing how to permanently switch to UEFI.
3. If you don't have a manual, you need to find UEFI in your BIOS and change it from Legacy
4. After changing, restart your Dell laptop

6.look for lost wires

You can get the error if your cable is connected correctly

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.
