ok lets go back to basics
switch the machine off, insert the USB, switch on whilst ticking the short boot menu key [usually F8 on an Asus]
from the short boot list, select USB and enter, the iSO should now load to ram for testing,
if it loads ok you can select install, when it comes to partitioning use the drop-down box to select your drive/partition, OR select install alongside windows and let the installer sort it out,
many newbies watch bloody you tubes and think they have to partition the HDD themselves, and this causes a myriad of problems, cant find the partition/wrong format/ wrong size/ add infinitum .

On this point, since I definitely am a newbie and I am following along the official Mint installation guide, the first time I tried installing it I chose “Install Linux alongside Windows Boot Manager” because I wanted to have both Windows and Mint…but then the installation took more than one hour until it crasched. The guide is instead suggesting i select “Something Else” and do the partitions myself. Shall I still try to go with the “Install Linux alongside Windows Boot Manager” option (maybe this time it will work) or trying with something else and do the partitions myself?

Hi, my laptop is an ASUS FX553V with Intel(R) Core(TM) i7-7700HQ CPU with 64-bit OS.

After a failed installation, booting Mint from USB now no longer works. First I got an error message that said

“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
Something has gone seriously wrong: import_mok_state() failed
:Not Found"

But I solved it by renaming grubx64.efi to mmx64.efi in my USB

Then now "bad shim signature - you need to load the kernel first" (I read somewhere that I need to disable secure boot, but on my Asus BIOS there is no such option)

It looks like I won't be able to install Mint. I also tried with Ubuntu and it crashed.

What can I do?

I had the same exact problem booting proxmox from usb. Asus B760-PLUS WIFI motherboard. Actually two problems, at first pc notified of gpt header corruption then this mmx64.efi issue. I pulled out all my drives had nothing except bootable usb stick, still the same error. I did reset bios, shorted, took out the battery, turned off secure boot, nothing, still the same. I did upgrade my bios the other day, so i downgraded my bios to an older version and voila, everything worked fine. Something went wrong with bios upgrade or secure boot stored some data about older op system boot information, i don't know. Weird.
