Installing Ubuntu 20.04 (U20). Laptop: Acer Aspire 3, model # A315-56. Laptop comes with 2 disks:

  1. Disk1: 256GB SSD
  2. Disk2: 1TB HDD

Laptop has Win10 on Disk1. Disk2 is just empty.

First attempt to install U20 on laptop was not successful due to: Ubuntu installation on computers with Intel(R) RST enabled.

After following the steps there, U20 is able to detect Disk1/SSD and I was able to install Ubuntu on it.

However, the second drive i.e. Disk2, remains hidden to Ubuntu. This disk is not found by lsblk, fdisk, lshw... nothing.

But logging out (from U20) and logging in to Win10, it is there, appearing as a huge 1TB empty hard disk.

Is there a step I missed to get U20 to detect this second HDD?

I have the same Acer laptop model and I faced the same problem. This problem doesn't have solution. Linux just doesn't support hdd controller used in this laptop model.

Change your hard drive's mode to AHCI mode in BIOS as it may be in RAID mode by default.Also, disable Fast Startup.

To access ACHI mode, you may have to do the following.

In BIOS, in the Main section, press Ctrl + S It turns on a couple of additional hidden settings. One of those, the one for the hard disk, should give you option to switch ACHI.

I partitioned a new volume E: from windows Then “try ubuntu” run terminal window

sudo lshw -c storage -c disk
sudo lshw -c storage -c e
sudo lshw -c storage

The last two commands I made up myself ‘doh. Only then could I see volume c and e in gparted. Then I format volume e as ext4 journaling root /
