Help with Windows 11 and Ubuntu 18.04.6 Dual Boot
So I'm in the process of trying to establish a dual boot with my Dell XPS 15 laptop. Windows 11 is the original and main OS however I need Ubuntu 18.04 for my work.
I have done a dual boot on my Lenovo laptop with no issues at all. However, in trying to do it on this laptop I keep encountering errors in the process.
Taking you through what I have done:
I have made a 700GB partition (now unallocated space ready for Ubuntu)
I have formatted my USB and burned Ubuntu 18.04 on it using Rufus.
I have changed the configuration from RAID ON to AHCI (as I saw that was an issue for Dell devices)
I have also disabled secure boot as that was an issue in a video I watched
But now when I go to boot from my USB I encounter the following error and shuts down the laptop (see photo)
I would greatly appreciate if someone could point me in the correct direction as I have no idea where to go from here

I am not much of an Ubuntu user, so not really able to offer much help.
If you need to describe the partitions, it would be best to include a snip of your Disk Management window.
You seem to be making changes which would not allow Win 11 to run, so I suggest you check with the Ubuntu folks as they may be more familiar.

@Saltgrass is spot on with that suggestion. This site at Windows Report may help. And this page at Linus Techi as well. And I also admit that Linux is not my forte.

Hi All,
Thank you for replying to me.
Turns out there is a simple solution (as is always the case) where I just had to copy one of the boot files and rename it to be the missing "mmx64.efi" file. This is where I found the solution so all credit to them:

Glad you found a solution. I was going to offer an alternative, if it would support your Linux workload: installing VirtualBox (free) on your Windows laptop and running Ubuntu in a guest virtual machine. I held off because the just-released VirtualBox 7.0.0 seems somewhat buggy out of the gate, though 6.1 is solid. Running this way would allow you to have both environments running at once, share resources and data between them, etc.
