I have a Precision 7510 that was working fine but we got the user a new system and went to repurpose the 7510.

I upgraded the memory and replaced the HDD with a SSD. Not an M.2 Drive, Its a WD Blue SATA SSD. The M.2 slot is empty.

Using the dell OS recovery download, I booted to the USB drive and it detected the SSD and went into the install.

When the install finished it does not recognize the SSD.

I have switched back to the original drive and it doesn't recognize it either, I even tried a 3rd drive that I had on hand, still no luck recognizing anything.

Bios settings I have 

Boot Sequence = UEFI

Advanced Boot Options = Enable Legacy Option ROM (checked)

SATA Operation = AHCI

Secure Boot = Disabled

I used a bootable USB drive to update the BIOS and Firmware to the latest Rechecked all the settings and it still wont detect any of the drives.

Boot sequence does not list "Windows Boot Manager" but I believe that is because it cant find a HDD and has no file system.

Like I said above this system was working fine until the reboot following the OS Restore.

I have searched through the forums and have tried many things but cant get anything to work.
