This is very important.

You need to make sure your Dell laptop is set to boot from the right bootable device. An incorrect boot order can make your computer boot from the wrong device thinking it’s the right boot device.

If you want your computer to boot from the right bootable device, you need to rank your bootable device as the first device in your boot order

For example,

If you want to let your Dell laptop boot from a bootable USB, you should go to your boot order located in bios and adjust your boot order to rank your bootable USB device first.

Here’s how to set the right boot order on your Dell laptop

  1. Make sure your device or drive is bootable with Operating system (OS) on it. If you want to boot from USB and you don’t know how to make it bootable, check here to learn how to create bootable USB. CD/DVD is automatically bootable when you bought it so you don’t have to make it bootable.
  2. Connect your bootable device to your Dell laptop
  3. Shut down your computer
  4. Boot into Bios on your Dell laptop
  5. While in bios, look for the boot tab. Depending on the version of Bios your computer is using, just make sure you find where your boot order is

This method is for you only if your Dell laptop can boot up to windows.

Here’s how to run the troubleshooter on your Dell laptop

  1. Boot up your computer normally or through Safe Mode if you have challenges
  2. Go to your windows logo on your Dell keyboard and search for Troubleshooter

In Command Prompt , run the following commands:

sfc /scannow /offbootdir=c: /offwindir=c:windows

If those two commands don’t fix the problem, then you must use DISM scan instead.

Here’s how

Run this command

DISM /Online /Cleanup-Image /RestoreHealth 

If this command also didn’t work, try this command instead:

Dism /Image:C:offline /Cleanup-Image /RestoreHealth /Source:c:testmountwindows

Dism /Online /Cleanup-Image /RestoreHealth /Source:c:testmountwindows /LimitAccess

This method isn’t for everyone and if you are still having trouble, move to the next method.

5. Make sure you’re using UEFI

When I had my own challenges with no bootable device found on my Dell laptop, this method worked for me and hopefully, it should work for you as well.

To fix the issue, you simply need to 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 versions of BIOS out there, I recommend you to check your motherboard manual and see how to switch permanently to UEFI.
  3. If you don’t have a manual, then you must find the UEFI in your BIOS and switch to it from Legacy
  4. After switching, restart your Dell laptop
  5. Check if the no boot device found problem is fixed. If not, move to the next method

6. Check for Lose Cables

You can get the no bootable devices found if your cable is to properly connect

It’s import you check your computer properly to see if there’s any loose cable. If there is, you want to properly connect it back.

The important cable to check is the cable that connects to your hard drive if you are trying to boot from a hard drive.

Also, check the cable that connects to your CD/DVD drive if you are trying to boot from a CD/DVD drive. If it’s not connected, connect it.

For those that want to boot through a USB, you want to make sure all your USB ports are working correctly.

Move no o the next method if you are still having troubles.

7. Disconnect USB peripherals

Sometimes, if there are too much or few things connected to your Dell laptop all at once, it might confuse your computer which can lead to you getting the no boot device found error.

So, remove everything connected to your Dell laptop such as mouse, keyboard, and another device.

After doing that, boot up your computer

If you are still getting the no boot device found error, move on to the next method.
