I am attempting to install Ubuntu on a HP Envy 15, my intention is to have this dual-bootable with the standard Windows 10 installation.

So far, I have made the following progress:

  • Created a live-USB drive to boot from
  • Disabled "Secure Boot" in the BIOS (to make USB boot available)
  • Booted onto the live-USB and run the installer

However, the installer does not "recognize" the internal HDD in the laptop.

I have run gparted, parted -l, fdisk -l and lshw -class disk all list the live-USB drive as /dev/sda, but the internal HDD is not present in the output from any of those commands.

As a diagnostic, I have tried enabling "legacy mode" in BIOS, and booting from the live-USB. It is clear form the loading screen that the live-USB is booting from BIOS (and not UEFI).

Running fdisk -l shows that the internal HDD has been successfully mounted as /dev/sdb.

Why is the disk presented in BIOS mode but not UEFI?

Given my intentions are to dual-boot with Windows 10, I understand that it is necessary to install Ubuntu whilst booted in UEFI mode?

  • can you please copy the `lsblk` output here ? – muhajirframe Dec 30 '15 at 08:32
  • Can you provide the brand//model number of the hard disk itself? (suspecting EFI driver only signed for use with Windows) – Fabby Dec 30 '15 at 08:36
  • @muhajirframe - lsblk shows sda/sda1/loop0, no reference to other disks. – jwa Dec 30 '15 at 08:46
  • @Fabby the disk is a Samsung ST2000LM003 HN-M201RAD – jwa Dec 30 '15 at 08:46
  • Was the issue resolved? – Charlie Nov 13 '16 at 01:27
  • @Charlie Afraid not. After failing to get this working the laptop went back to the store. – jwa Nov 14 '16 at 08:55
  • @jwa - sorry to hear that. Your problem perfectly describes the problem that I am having with a Dell XPS 15. Dell Tech support have just told me that this is unresolvable, so my laptop is going back to the store as well. – Charlie Nov 14 '16 at 16:42

    Does this answer your question? [Why does the Ubuntu installer not detect the hard drive during installation?](https://askubuntu.com/questions/99038/why-does-the-ubuntu-installer-not-detect-the-hard-drive-during-installation) – karel Feb 18 '22 at 00:58
