The Ubuntu installer defaults to a MBR drive setup when a UEFI BIOS isn't detected. It still uses LVM as the automatic partition scheme.

In Fedora there's a way to force the installer using a boot flag (inst.gpt) to create a GPT drive with LVM.

There's not currently a way to do this on Ubuntu so how do I convert the MBR drive to GPT with a LVM scheme?


Use gparted or another partitioning tool from the live cd to format the drive and create a GPT partition table, then install Ubuntu. It will keep the existing partition table.

  • This doesn't work because the auto installer simply wipes out anything you set up and creates a MBR+LVM setup – warsong Feb 20 '18 at 9:05
  • Choose the manual option and partition it yoruself. – psusi Feb 20 '18 at 19:46
