I am attempting to dual boot ubuntu 18.0.4 with windows 10 on my new dell inspiron 7472, and i was following this guide: Dell guide. I followed all the steps up until I was told to boot from my bootable usb drive, created with rufus with GPT. whenever I enter the boot menu, the bootable medium is not displayed, I have tried flashing it with both MBR and GPT to no avail.
Is there a step I have missed?
EDIT: I have managed to boot from usb by using etcher with a different USB, however there when i click install, it only shows the option to install to the USB itself, and doesnt show the installation type window
