I've just gotten a new laptop (Acer Aspire A315-56), where I can't see my HDD from a Linux live boot. When I'm opening GParted, it's only showing one disk and it's the USB Drive from where I've live booted it. My laptop came preinstalled with Windows 10 Home.

I've looked up Ask Ubuntu and similar forums, and according to the suggestions, I've tried out the following:

Set the SATA Mode to "AHCI" from "Optane without RAID"

Disabled Fast Boot from BIOS

Disabled Secure Boot

Disabled Fast Startup and Hibernate from Windows 10 Power Options

Unfortunately, none of those turned out to work for me.

As I'm not able to see the HDD from Linux, I'm not able to install it. Can anyone help me out with making the HDD visible from Linux? Using a Virtual Machine isn't really a solution.

Also, I've checked that upon hitting sudo lshw in the terminal, the SATA Controller shows up there. So, the SATA controller's driver is in the kernel.

I'm live booting Ubuntu, if that helps.

    what does lsblk show you?

    It's probably not a HDD but a SSD. And that means it could be a NVMe SSD, which has nothing to do with SATA at all; a NVMe SSD is essentially a PCIe device, so check lspci. In Linux, NVMe drives have a different device name scheme: /dev/nvmeXnYpZ, where X is the number of the NVMe drive, Y is the number of a storage namespace within it (in consumer-grade device, probably always 1), and Z is the number of the partition. The driver for NVMe devices is a kernel module named nvme.

  • @BitFreak this is what lsblk gives: pastebin.com/Cbs2ppWt Aug 17, 2020 at 14:56
  • @telcoM It's an HDD for sure. You can check the specs for the given model. Here's what lspci gives: pastebin.com/S9NaRSYt Aug 17, 2020 at 14:59

Its not really a solution more of a workaround, put the laptop to sleep and wake it backup and the SATA drive will appear.

If your kernel has the debugging enabled for power management you add test_suspend=mem and suspend.pm_test_delay=2 to the boot time options. unfortunately most kernels are released without them compiled in.

The main thing is after getting the OS installed, you have to wait for the kernel to start booting shut the lid or use the keyboard shortcut to put it to sleep wait a second wake it up and let the computer finish booting, or compile a custom kernel and enable the power management debugging and suspend test options in the config.
