Booted from hdd no nrldr detected reboot

Hello,

Hello,
I have a desktop pc and I had a problem with my hdd. When I booted from this hdd the Process was frozen ando gave me a black screen. I noticed that for about a minute the hdd light was giving a "reading" indication and then it was off. After rebooting it gave the message "no nrldr detected reboot". I rebooted and entered into BIOS.There the hdd was not detected at all. I tried the steps 1,2,3,4,5,6 I found on another post here (https://ccm.net/forum/affich-691816-sata-hdd-not-detected-in-bios-but-sometimes-it-does and although at first the hdd was detected in BIOS, when I tried to boot the same problem occurred - no booting and then no hdd in the BIOS
