    Once installed you will have the correct mmx64.efi in both /EFI/Boot & /EFI/ubuntu.

    The mmx64.efi is used for a user to create a UEFI key. That in required if Secure boot is on & you are installing any proprietary driver like nVidia or Wi-Fi. Ubuntu cannot provide key for proprietary software that it does not create. A user can, but then assumption is that user knows if software is ok for UEFI Secure boot or not.

    What software did you use to create Ubuntu live installer onto flash drive? Make sure you have UEFI, not just BIOS or CSM version setting. ISO is for both and should be configured for both, but some software used to create live installer seems to make only UEFI or only BIOS versions.

    Can't install Ubuntu 18.10 on XPS 15 9570 - EFI\BOOT\mmx64.efi not found

    Supposedly bug is fixed:
    System fails to boot with \EFI\BOOT\mmx64.efi - Not Found
    https://bugs.launchpad.net/ubuntu/+s...2/+bug/1798171
    i created it on rufus following the directions linked from the download page on ubuntu.com. I reformatted the usb and am re burning it right now to see if the file is there.

    I wonder why it was booting when i had it in legacy mode without that file....

    Re: New Win10 / Ubuntu install process

    I have never used Rufus, but I think this screen shot is not correct for UEFI.
    UEFI has CSM.
    CSM - UEFI Compatibility Support Module (CSM), which emulates a BIOS mode, only available with secure boot off.
    https://tutorials.ubuntu.com/tutoria...7.1573397008#2

    Most systems will boot in either UEFI or BIOS from MBR or gpt partitioned flash drives. Only a few UEFI/BIOS systems were more particular and wanted one or the other.
    Some other methods use dd or some software to make dd a bit less dangerous and that makes a hybrid DVD/flash drive. Flash drive is then not partitioned at all and at least first sectors have to be zeroed out to allow partitioning and reuse. The main issue with dd is that is uses device likr /dev/sdb. But some BIOS make flash drive sda and internal drive sdb, so then you erase your system, if you have that type of UEFI/BIOS. Most users do not note detail which can be critical.

    Make sure in Rufus you select UEFI, not UEFI/CSM and probably gpt partitioning so it defaults to UEFI?

    Thanks!!

    after remaking the USB it still did not have the file so i copied it. That worked!

    Should i make the partition in Win10? and do I need a swap partition?

    there is no UEFI only option, There is only one target system option

    Re: New Win10 / Ubuntu install process

    If you choose gpt, is it then UEFI?

    New installs use a swap file, so swap partition is not required.

    Only use Windows 10 tools to shrink NTFS partitions. Windows has been known to rewrite partition table and "forget" to include Linux partitions. Data is still there, just missing entry in partition table. Bug since Windows 7 with any major update. Some Windows 10 post recently have shown similar issues with AOMEI partitioning tool.

    If I select GPT then the only target option is "UEFI (non CSM)"

    does it make a difference? the drive works after making the copy of the file...

    Re: New Win10 / Ubuntu install process

    It sounds like it makes UEFI only or CSM boot flash drive.
    Did the version using MBR and CSM also boot in UEFI boot mode or only BIOS/CSM boot mode?

    And then copy to create mmx64.efi is required with which version or both?

    Thank you for all your help. I got Ubuntu and Win10 dual booting on my machine now.

    The 3 things I did were: 1) disable fast startup in windows 2) disable secure boot in UEFI 3) Copied the mmx64.efi on the USB stick. That seems to have everything working fine now.
