        We need to get the PC to start from the USB key
        or have the USB key recognized in the boot menu
        do you have another PC?

        I don’t understand why the USB drive isn’t recognized
        return to the menu here:

        and set "USB hard drive" in the 1st position using the "Enter" key
        then do "F10" to save
        and restart the PC with the USB drive plugged in

        so yes the hard drive is indeed recognized by the BIOS " ST 500 DM002 "
        it's a 500 GB drive
        go to the " Advanced " menu
        give photo

        USB key plugged in
        restart and press "Esc"
        instead of going into the BIOS you should have a menu of options
        provide photo

    11. The problem is that the computer starts up but does not display a menu with conventional files and therefore I cannot access the files.

        restart the PC and do it as for BIOS access
        choose " boot option "
        it should be " F9 " I think

        So these must be the startup files that are corrupted
        we'll try to recreate them
        do you have a USB drive or Windows 10 installation DVD?

        check in the BIOS if the hard drive is recognized
        attach a photo of the bios if you don't find it

      Hello
      your PC can’t find the hard drive or the system startup files
      check in the BIOS if the hard drive is recognized
