Precision 7670 will not boot to internal SSD or to any bootable USB

The internal SupportAssist OS recovery runs the download and restarts but the system freezes at the Dell Logo with a portion of the OS circle on the screen.  The Bios has been updated and reset to factory defaults. A new blank SSD has been installed.  An OS recovery USB has been created .  The system diagnostic .    The SupportAssist | On-Board Diagnostics  passed all components but  also gave this result  "Undefined Error Detected" , continue did not help.  Two non-Dell bootable USB devices will not boot on this laptop.

    Hi

     

    Surely the recovery download goes to the recovery partition (mine did)?

    Which means the storage is recognised and available, hopefully?

     

    So is the Secure Boot option ON or OFF?

    Whatever it is, can you try the alternate?

     

    If the BIOS has been set to factory defaults, that could exclude any and all storage/bootable devices.

    So try the One Time Boot menu if you can, possibly F12?

     

    If in doubt please ask.

      Kind Regards

    @anne_droid​ 

     

    Boot attempts were tried with Secure Boot  on and off. No success. 
    One Time Boot  F12  to select the USB did not result in the system booting. It found the USB and started loading files then either froze or restarted the computer.
    All the various CMOS, power and Motherboard resets have been tried.

     

    I tried 6 different bootable USBs.  All failed to boot in various ways.
    Hiren’s Boot PE,  Windows 11,  Windows 10,  Dell SupportAssist recovery,   Acronis Clone software, Killdisk (Linux).

     

    Here is the latest attempt.

     

    Installed a new blank SSD. Booted to F12,  selected SupportAssist OS Recovery.
    Connected to WiFi successfully.  The Files downloaded from Dell successfully.
    The computer rebooted to the Dell Logo screen,  the OS progress circle  started and stopped.
    Let it sit for over an hour  with no change, no progress.

     

    Shut system down and removed the SSD. Checked it’s partition table on my test system.
    There were no partitions created. 

     

    It seems like the laptop finds all the hardware but  freezes or reboots at some point  when it is trying to load the OS . Any OS

    Hi

     

    I generally try to boot a live linux first.

     

    Then if that works, add storage.

     

    It must post because you download the recovery file.

     

     

      Kind Regards
