I have used the same USB stick to re-install and gotten this error and have downloaded 3-4 other ISOs and none of them will boot. I download the ISOs on Windows 10 and use Rufus to make a bootable USB. I've done this about a hundred times.
But, every time I try to boot with any of them I get this error that flashes just before the install screen pops up (which will not install). It took me a while to catch what it was saying but, I got it with my phone camera:

Code: Select all

               Failed to open \EFI\BOOT\mmx64.efi - Not Found
               Failed to load image \EFI\BOOT\mmx64.efi: Not Found
               Failed to start MokManager: Not Found

OK, my coffee's finally kicked in this morning, but this still doesn't make any sense to me. How are you able to run the installer if you can't even boot from the USB stick now?

https://mxlinux.org/wiki/system/create- ... s-desktop/ may help with USB creation and booting issues. There's a video about how to make an MX USB when Rufus doesn't work right or something like that.

Just to make sure I installed Xubuntu 19.10 beta from a 64GB USB stick and then I did what you mentioned and downloaded the ISO while in Arch Linux. I was then able to re-install MX_Linux 18.3.
I just installed the 390.129 driver from the test repo and am about to reboot. Sure hope like hell it goes past the flashing underscore.

The only installations screens found in the live USB version of MX are the MX Installer to install MX Linux, MX Updater to install upgrades, Synaptic and MX Package Installer to install new packages. So again, I don't know what you're talking about, unless you possibly mean the live USB's boot menu?

If you're having problems getting a live USB to boot in UEFI mode I suggest that you follow the instructions in the wiki page I linked to in my last post, read the appropriate section of the manual (there's a link at the top of the forum), search the forum to find the help and advise that's already been given to others because maybe that will also be your solution, and if not, start a new topic about getting a live USB to boot on your specific computer.

One tip I can give you is to format the USB stick again in Windows, as Fat32, then try burning the iso with Rufus again, making sure you choose the appropriate options to make it UEFI-bootable. Sometimes things get messed up when you reburn isos to already-used USB sticks and you need to wipe them clean by reformatting them and start over fresh.

Edit: first, do what fehlix suggested below. He knows more about fixing booting issues (and about many other Linux things) than I do.

You might probaly "fix" the issue in a way as mentioned here: https://forum.mxlinux.org/viewtopic.php ... 02#p520002
by copying grubx64.efi to mmx64.efi within the /EFI/BOOT folder on the USB-stick.

But, I think it is too much to ask for a user to mix test repo packages with stable packages. I know a little but, just consider me a regular user. I do not feel comfortable installing any kernel this way.
