What is the recommended boot order for Windows 10 (Creator Update) desktop pc

Could someone tell me the recommended boot order for Windows 10?  Below is an image showing my current boot order.  The reason I ask is that I like to keep a usb plugged in all the time for Windows 10 File History backup to be performed and when I do that and reboot the computer I get the following error:  "An operating system wasn't found.  Try disconnecting any drives that don't contain an operating system".  Thanks for your help!

If you are having a problem booting your system:

  1. Try loading BIOS defaults, saving and reboot your system

Did you make manual changes to your BIOS, or did this booting problem happen after a Windows Update?

Sorry, I just read your question again and if you only get this error when the USB drive is plugged in - disable the options 'USB Boot' and Boot to Removable Devices' so your system does not try to boot from the flash drive . . .

Thanks for your reply DaveM121.  I followed your suggestions and I did not get the error message when I rebooted.  

With these settings you recommended,  if my computer failed in some way would I still be able to use successfully the bootable usb I created with Windows 10 "Create a Recovery Drive" feature?  Not having ever had a computer failure where I couldn't turn the computer on, I don't know if I could boot to the boot sequence in order to re-enable the USB Boot.  Same with the 'Boot to Removable devices' disabled, if I needed to boot from a bootable repair DVD?

For Legacy BIOS, it's always best to have the hard drive set first to boot so nothing else can interfere. 

To boot media use the  BIOS Boot Menu Key to avoid issues like flash stick restarting install again during required reboots. 

For UEFI firmware which is replacing BIOS, the Windows Boot Manager will be invoked to be first when you correctly install WIndows by choosing the boot device as a UEFI device (only).  Leave Windows Boot Manager first at all times. 

If anyone still has Floppy in the Boot order, I would physically uninstall it because it can cause strange issues even if correctly removed from the Boot order and disabled everywhere it appears in BIOS.  I've found a number of old PC's which installed floppy was blocking from starting that were still good otherwise.

You can test booting your Recovery drive following the above. 

Hope this helps.   Feel free to ask back any questions and let us know how it goes.  I'll keep working with you until it's resolved.

Catherine, if you ever have a computer failure and need to re-install Windows 10, you simply re-enable these options and you will be able to boot from the installation Media . . .
