Only Solution for OptiPlex 5040 and 7040

  1. Go to the Dell Drivers and Download site for your product.

  2. Select the dropdown for Operating System then select the option to "Download the Windows Recovery Image"

  3. When the download is complete the issue will be resolved by the new image installed as this has drivers included.

The 5040 does not support ATA or FAT32 MBR partitions nor does Windows 7 or 8 or 10.  You can only install on GPT partitions with SECURE BOOT OFF legacy ON NON UEFI BOOT.  There is no ATA sata operation and therefore you MUST USE AHCI F6 drivers for the install to work.  There is support for this but its not free.  Advanced format drives REQUIRE F6 drivers.
