I downloaded the 18.04 ISO from http://www.ubuntu.com/download/desktop

I transferred the ISO to a USB

When I restart my computer, the installer loads up.

I am able to:

  • Select my language and click "Install Ubuntu"
  • connect to my WIFI network
  • Tell Ubuntu to install additional updates

Problem

When I get to the screen with the partition table, the table is blank.

The field below it that says "Device for boot loader install:" is filled in with /dev/sda and no other options are available.

If I click continue I get an error saying "No root partition is defined" (duh) and If I click one of the +/-/change buttons, the page basically becomes unresponsive, although I can move the mouse.

This install process is identical to mine, except mine completely skips step 5. This must be causing the problem

Clicking the Try Ubuntu option does work as expected.

I have checked the disk for errors and there were none.

I have done a memory test and no errors were found.

I also performed a secure erase on my hard drive, thinking it might fix the problem. It did not.

I also tried clearing meta data with the following command:

sudo dmraid -Er /dev/sda

That didn't work either.

Nothing seems to work.

Edit: I am using a Lenovo laptop with Windows 10 currently installed

  • You forgot to set root partition. Are you sure you have created a new partition, format it and set it as root? – Aryo Adhi May 18 '18 at 02:29
  • Are you sure Windows fast start up is off? http://askubuntu.com/questions/843153/ubuntu-16-showing-windows-10-partitions Windows will also turn it on with updates.

    I'm voting to close this question as off-topic because it turned out to be an erroneous BIOS setting. – David Foerster May 19 '18 at 18:38

Figured it out. Had to switch to AHCI in my BIOS.
