Hey everyone! I'm trying to set up Linux Mint on my computer and I've run into some frustrating issues. I've followed the steps from the installation guide up until the point where I'm supposed to boot from my USB drive. My plan is to have a dual boot system where I can run Linux alongside Windows 11, which is currently on a separate drive.
Here's what I've done so far:
1. I disconnected the Windows drive and connected a blank 1TB SSD for Linux, then plugged in my USB with the Linux installer.
2. I booted from the USB and started the installation, but it stalled on the "Who are you?" step for hours.
3. After restarting, I got an error saying: Failed to open EFIBOOTmmx64.efi - Not Found.
4. I formatted the USB, flashed it again with Linux Mint, and tried booting it but got the same error. Now I can't boot from the USB at all.
I've read online that this might have to do with secure boot settings, which I toggled ON and OFF, but still no luck. What am I missing here? Any help would be greatly appreciated! 🙏

When installing, follow the instructions specific to the distro you’re using. The mmx64.efi error suggests an issue with secure boot. If you plan to disable it, be aware that not all distros will handle it the same way, so check the documentation for your version of Linux Mint!
I recommend booting into something like GPARTED to format your 1TB SSD again. After that, try booting from your Mint USB once more.
Honestly, if your Windows and Linux are on different drives, you might not even need a dual boot setup. You can just choose which drive to boot from directly. If you connect the Windows drive, it will boot into Windows, and if you connect the Linux drive, it will boot into Linux. Just remember to keep secure boot turned off, though!
Definitely! As long as all drives are connected, you can install both OSes. Just make sure to disable secure boot. After that, you should see the boot menu allowing you to choose your OS at startup.
Have you checked out this link? [GitHub WLI](https://github.com/rltvty2/wli). It might help with your installation issues!
Wow, I had no idea this existed! I'll definitely give it a shot. Thanks!
Make sure to verify your ISO before writing it to the USB. If it still fails to boot, your USB drive might be faulty. You could try another USB stick if you have one available.
Is there a way to still get a menu at startup where I can choose which OS to boot into, even with them on separate drives?
