I Recently took apart my dell latitude e6420 apart , everything was ok until I put it back and booted it up and to my shock they say no boot drive is detected , when to check the If it was properly installed and it was , went back to BIOS and to my shock they say there is no HDD whatsoever even though it’s connected to my pc and keep in mind that My pc was working just fine before I took it apart
