I have a windows 10 DELL XPS 15 7590. The steps that I have taken to dual boots are:
Download UBUNTU 18.04
Set up a live USB using etcher.io
Create an unallocated partition to install Ubuntu
Boot in to USB and install Ubuntu
However during this step. I’m not presented with the option to install alongside Windows 10. The only drive it shows is my USB and that doesn’t work. I don't even get the option to replace windows with Ubuntu. Please could someone help me I’ve been stuck for a long time.
