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

  • Try creating Bootable usb with Etcher. Rufus has lot of unnecessary options. Get it from etcher.io – harshit Dec 8 '18 at 18:36
  • @harshit Thanks, this has gotten me further but a new problem still awaits – BastiatAdmin Dec 8 '18 at 20:38
  • Almost all Dell need UEFI update, if SSD, SSD firmware update and then settings in UEFI changes. Drives need ot be AHCI, not RAID. And if dual booting with Windows install the AHCI driver first. Turn off fast start up in Windows. help.ubuntu.com/community/UEFI & askubuntu.com/questions/221835/… & askubuntu.com/questions/221835/… – oldfred Dec 8 '18 at 23:40
  • @oldfred Changing to AHCI bricked my device, I attempted to install the drivers then change my SATA operation, however it simply led to me being forced to factory reset my device. – BastiatAdmin Dec 9 '18 at 20:12
  • Factory reset will change all your UEFI settings. I have 5 or 7 that I change, so keep a list. Did you install AHCI drivers into Windows first. The only time to stay with RAID is if you have RAID 0. – oldfred Dec 9 '18 at 21:06
