Error "Failed to open EFI\BOOT\mxx64.efi not found" Linux M

Hello!
I had a problem trying to install Linux Mint. To make a long story short, I used the OS several times on my USB stick to test things and make sure everything was fine... and everything was working perfectly. Then, when I tried to install the OS permanently on my machine, the Live Session wouldn't start from the stick, the following error showed up during startup on my PC:
"Failed to open EFI/BOOT/mxx64.efi not found
Failed to load image ??: Not found
Failed to start MokManager: Not found
Something has gone seriously wrong: import_mok_state() failed: Not found"
After formatting the stick several times, attempting to put Linux Mint on it, several restarts, and multiple searches, nothing works, even though everything was fine until now...
What should I do?

Hello
You may have tried to install in EFI mode while your system was in classic BIOS or MBR mode.
Not all Live-iso are always suitable for proceeding to an installation; sometimes you need to change the tutorial and also the ISO before installing.
This time you need to change the tutorial and maybe the ISO again to perform a "boot manager repair" on the partitions or on the hard drives of the PC. We will wait for installation specialists in Mint or Ubuntu for practical guidance.
Hello,
Difficult to interpret without further details.
We don't know what's on the hard drive (nothing, another operating system, dual boot, or replacement in the latter case?) but if there is something and on a recent computer, there is a good chance that the BIOS is booting from UEFI and that the partition table is GPT.
Among the commonly documented causes:
-Disable the secure boot in BIOS and boot not by letting the system automatically read the USB key but by calling the Boot Manager using the appropriate function key at startup and choosing the USB device in its UEFI form.
-The problem is often mentioned with at least some versions of Rufus and certain poorly made Linux Mint ISOs. The configuration of Rufus during creation is well documented all over the Internet and should not pose a problem; however, installation will then be impossible unless the Rufus ISO is modified accordingly, which is a bit technical. In the presence of such a cause, it is often quicker to test (at least if we start from Windows) by creating the key via Ventoy (or Balena if we start from Linux).
Hello,
to be more precise, Windows 11 is already installed on my machine.
So to try to solve my problem, can I disable secure boot and create my USB stick using Ventoy?
If the Linux Mint ISO is faulty and thus conflicts with Rufus, yes, it doesn't hurt to try.
But that still doesn't tell us whether we want to install Linux Mint instead of Windows 11 or as a dual boot.
In the first scenario, the disk must be formatted; in the second, we need to create a new partition by shrinking the space on the first one. In the second case, the standard Linux installation will automatically create the necessary Linux partitions, which we can manage the size of by choosing a custom installation.
I want to completely uninstall Windows, sorry for the lack of precision...
My problem was solved by disabling secure boot and using Ventoy.
Thank you very much for your help, and have a great day!
