I have an issue installing Ubuntu 20.04 on my Dell XPS 15 9550.

Here are my actions:

  1. Created a boot drive using Rufus in MBR mode
  2. Disabled Intel Rapid Storage controller
  3. Chose my USB stick from UEFI boot section
  4. After GRUB had a black screen
  5. Attempted to fix the issue by changing quiet splash to nomodeset (didn't work)
  6. Attempted to boot from legacy boot section (got me into the live image)
  7. Upon trying to install Ubuntu Windows 10 was not detected (theory: Ubuntu can't see Windows as the live image was launched in legacy mode)
  8. Attempted to partition the drive manually and install Ubuntu that way, however GRUB failed to install to its partition
  9. Formated the USB drive from Windows using Rufus again, but this time using GPT partition scheme
  10. The drive wasn't detected as a bootable device

At this point I am not sure what to do. I'm guessing that I need to change some of my BIOS settings, but I don't know to what.

The strange thing is that I managed to install Fedora dual boot previously on this machine, but after removing it I wasn't able to install Ubuntu. (I removed both the partition and the GRUB bootloader to get a clean start)

Any advice will be welcome!

edit 1: So added another EFI boot option by using the BOOTX64.EFI file in my BIOS however, I am met with a black screen after GRUB. I tried nomodeset again but that did not help.

Did you install Windows from legacy boot?

I went through all of these recently.

I guess you should install ubuntu the way you installed Windows(both legacy or uefi)

I installed Windows from legacy boot and my bootable flash drive containing ubuntu was uefi, I didn't had "install along side Windows 10" option until I made my bootable drive legacy mode(using rufus).

P.s. If you can install both Windows and ubuntu with uefi boot(and gpt papartition scheme) you're less likely to run into problems with making enough partition for both operating systems.

So what worked for me is that I instead downloaded the Ubuntu 18.04 ISO and then upgraded it. I am not sure if I did an extra step, but Windows was detected and I didn't have to go into legacy mode.

For anyone in the future reading this thread, maybe attempt this. I've still used Rufus to create the installation media.

Thank you to all the people who helped me!
