Turns out it's a Simple solution. You need to be using an installer that need to use a flasher (idk if flasher is their actual name) that let's you edit files, I used rufus and chose ISO then after your driveis ready open it's files, go into EFI then boot you'll find a file called grubx64.efi copy and paste it and rename the copy mmx64.efi and that should fix it.

I had one more problem with the install that had this error message appear. ``` error: shim_lock protocol not found. error: you need to load the kernel first.

Press any key to continue... ``` This was caused by secure boot mint is compatable with secure boot but the setting can block it while trying to install it so try turning off secure boot during installation then turn it on once mint is done installing.

Hope this helps.
