Hi thaleneb,
Thanks for providing us this information. Please check the steps below for disabling the floppy drive which should resolve this issue:
Keep tapping F2 key on the keyboard while starting the system at Dell logo.
It will take us to a different screen called BIOS.
On this screen only keyboard will function so you need to use arrow keys to scroll through the options and enter key to select the highlighted option.
Select Standard CMOS features from this page.
Under the same page select Drive A as None.
Press F10 to save and Esc to exit.
This would restart the system kindly check if the error still occurs.
If you have any further queries, please feel free to contact us.
Thanks and Regards
Sandeep P
