I'm using a 500 GB HDD and upgraded from Ubuntu 16.04 to 18.04. Today I installed Windows 10 and Ubuntu 18.04 on USB easily, but all of a sudden after USB bootup my 500GB HDD has vanished.
I tried checking through "DISKS" but cannot see physical presence. I need to get the HDD back to show. The hard disk seems to be OK, no noise etc. Healthy. I need step-by-step instructions because I am using a live USB here and I cannot afford to lose data.
Phoenix BIOS (Lenovo B570e). Will the drive work if I plug it in another laptop as external USB drive (USB caddy)?
Below are the current results of
sudo fdisk -l (with loop devices removed):
