Wierd error message after bios update. PLEASE HELP

[alphieodondi21]

I had to post this again bc no one answerd my last post . So i tried to do a bios update on my optiplex 390 pc. So i created a bootable usb drive (on another pc because i can't access windows because my hard drive isn't found for some reason) by following these instructions: https://www.dell.com/support/article/us/en/19/sln143196/how-to-create-a-bootable-usb-flash-drive-using-dell-diagnostic-deployment-package-dddp-?lang=en

No one is helping me on the Dell forum so i thought I'd try asking here
So i did that and then downloaded the optiplex 390's latest bios and moved the .exe file into the bootable usb drive. I then put the usb in my optiplex and booted into the drive and shows me this. Idk what to do, please help!!

Those errors are for missing DOS boot files.

For whatever reason, your bootable USB drive isn't bootable.

Well there's a Diag C:\> so something has happened. Can you tell where the C drive has been created?

 

[jay32267]

well....lets assume it booted to DOS

C may be the USB stick

Type dir and see if your exe file is in the root

if so I would assume you would run it....but follow whatever directions you have

Yes, check if those two files that are mentioned are there. It needs to create a D drive in the RAM to load the diagnostic files.
