#Problems with Linux Mint installation in dual boot (Acer PC

Hi everyone, I'm having a problem installing Linux Mint cinnamon, or I think other Linux distributions in general. On my Acer Aspire E5-475, even though I installed Linux with a dual boot, the Linux boot menu doesn't appear; it boots directly into Windows (I'm using Mini OS, I don't know if that's relevant).

I tried repairing the bootloader with the Linux Mint live installation, but that didn't work either. (I'll attach the boot log to see if that might help.)

At this point, I'm asking for help because I really want to experiment with Linux, but this bad start is honestly making me dislike it, and it makes me sad to feel like Linux is holding me back when so many videos speak highly of it. I really want to experiment and put Windows aside for months to share my experience with others. Any help for this newbie would be greatly appreciated.

(P.S.: I speak Spanish, but since only English is allowed here, I ask for your patience as I would have to translate everything.)

A small second note: my USB drive is booted with Ventoy because the other bootable drives were giving me a lot of problems.

#

Another thing, this happens when I install Linux Mint. I don't know why, it's just a 126 GB partition with no name, as if it were using something, but I actually know what it's doing...

then run boot repair

#

also check the priority list in your BIOS

#

make sure linux mint/ubuntu is first

You may have to look through BIOS settings for something about trusting an EFI file. You may have a function key at boot to access boot menu without going into BIOS, there might be a shimx64 or grubx64 file to try booting to

Can you disable Legacy/CSM support in BIOS and run the boot repair again?

Found possible fix, under Security, it shows select an EFI file as trusted

#

Might only be able to change if a Supervisor password is set

See if you can change it, may need Secure Boot set to custom

Right now is shows Secure Boot mode standard, it might change to custom if you select the efi file as trusted

I tried, but the screen is still black as if it's locked, even after enabling Secure Boot. I give up on Linux in general; it seems my laptop is cursed. Sadly, it also seems that changing operating systems isn't for me, at least... since I used MiniOS, maybe the system is doing weird things, preventing the boot process from working correctly for Linux and Windows. So, I'll try a kamikaze method: switching to a regular Windows 10 and then trying again.

Did it ask you for a name after selecting an efi file?

¯_(ツ)_/¯

Even after setting a supervisor password? You may have to exit BIOS and go back in after that

#

It wouldn't allow you to change Secure Boot mode from standard to custom?

#

Might want to try Windows 10 or 11 and see if there is a BIOS update to fix that garbage. I know I was able to do it on my Acer laptop but it is only a couple years old

#

But that booted into Mint after I installed it and I did that just for a test

You may want to back up everything before installing Windows

.... shit

wise leaf
#

I don't trust Windows

crisp oriole
# wise leaf I don't trust Windows

The method of switching to Windows didn't work xD (I switched to a Windows LTSC) oh well, I'll try the other method which is to install Linux and remove Windows

#

¯_(ツ)_/¯

I don't know how to use that...
