Dell Optiplex 7470 All-In-One BIOS Flash

[RossCummingsOneIT]

Hi All, apologies if this is in the wrong part of the forum

 

I have a 7470 AIO that has a BIOS failure - recovery page appears with 3 options to recover, rollback or go to factory defaults but all fail.

 

I need to create a bootable USB to reinstall the BIOS but the exe I get from Dell once extracted does not have a .hdr file to rename to a .rcv file

 

My machine is out of warranty so Dell support aren't being helpful, but I can't find the .hdr file anywhere and presumably I cannot just put the .exe into a bootable USB as it needs the .rcv file

 

I can't get into any sort of MDT/F12 prompt, no F8 for CMD, no recovery options etc so my only option is to boot from USB to re-install the BIOS

 

Any help would be appreciated!

Looks like the rcv file is available to download from Dell support?

Life saver! I was just on the main Dell Driver site and not the drilled down BIOS page - much appreciated
