I have a laptop which has a 256GB internal drive with Windows 10 Enterprise installed on it and it works fine.

I want to install Ubuntu 18.04.02. I have created a LiveUSB and can boot into the OS by selecting the "Try without installing" option.

However, when I try to install Ubuntu, I get a message saying that I do not have enough storage space. I have tried sudo fdisk -l, but it does not list the 256GB drive. I have also tried using gparted, and it too does not list the 256GB drive.

The laptop is a Dell Latitude 7490.

EDIT 1:

To shut down Windows 10, I opened the command line and typed shutdown /s /f /t 0

sudo fdisk -l shows me the following:

sudo parted -l shows me the following:

  • You need to shut up Windows properly. What does sudo parted -l show?

    When running the installer did you use "Something else"? If so was the Windows partition listed? when installing using Something else make sure the device for boot loader installation is the drive, (not partition), you are installing to. Feb 28, 2019 at 5:41

Two things need to be done:

  • Create empty space on Windows
  • Turn off Fast Startup

Create empty space on Windows

The first step is to allocate enough space for Ubuntu. With your 250 GB drive 50 GB to 100 GB could be a good balance for Ubuntu.

In Windows 10 start menu type "Disk Management" and a screen like this appears:

  • On this machine "Disk 1" is used to store 3 Ubuntu partitions and one shared Windows/Ubuntu data partition.
  • In order to create extra Ubuntu partitions, the Windows Partition was shrunk from 477 GB to 363 GB.
  • Make sure you create empty space at least 20 GB in size however 50 GB to 100 GB would probably suit your needs.
  • To create empty space you need to shrink the size of the Windows 10 partition.
  • Do not worry about creating a partition in the empty space. Ubuntu Installer will do that for you.

Turn off Fast Startup

When you boot your computer Windows 10 has a feature to speed up the boot process. This feature though makes it impossible fir Ubuntu to access Windows (NTFS) partitions because they are "locked".

In Windows 10 click the start menu and type "Power Options". In the screen that appears click Choose what the power buttons do:

  • Notice the check mark next to Turn on fast startup (recommended). Uncheck it.
  • Note to keep Hibernate unchecked.
