Idk any tech support communities, but you should try booting into BIOS to see if your storage drive is detected. If not, it probably failed (read: it's dead, fam)
You could try to see if you can reinstall the OS but if the BIOS doesn't detect the drive, I doubt the OS setup will.
While the data loss will suck, a new drive isn't very expensive. Plus if you're still on a HDD, it would be a good time to replace it with an SSD.
As someone who found elementor the only thing that was working at the time - any suggestions to do better? I have no coding experience fyi
