You might throw insults at some things. Throwing insults at people normally does not help in getting answers.
Ubuntu live CD also allows you to install OS on disk and verify that your laptop can boot generic Linux OS.
People are trying to understand your setup why trying to guess what hardware you are using with you giving as little as possible.
Secure boot tends to work with Windows, but it is highly likely to break with Linux. Keep it off with Linux.
MSI GF63/75 manuals show that they support both UEFI and Legacy boots. Change to legacy boot. Make sure that you have nvme and ssd devices listed in boot device list. Both laptops have manual page telling how to change boot mode.
I didn't insult anyone? I mentioned wanting to install it internally instead of running by USB because I see LibreELEC is used often by USB, which I know it can do, but I don't want, for reasons I listed. I fail to see how that offends any actual people.
No one asked for my laptop. I didn't list it because I frankly didn't think it was needed, the LibreELEC installer just says "Generic" for Intel/AMD so I figured it didn't matter, we're also very far removed from laptops having actually different parts and firmware than desktop computers. It's an MSI GL63 8RD.
SecureBoot is off. UEFI is changed to Legacy. Doing a new, fresh install with these settings changes, and nothing changed, still doesn't boot, and BIOS still doesn't recognize any boot devices. Posted a new log. Don't know if it's any different.
I'm trying to install it to an NVMe drive, although like I said I also tried a SATA HDD where the same thing (read: nothing) happened.
I guess I'll try some older versions. Maybe something bugged out. I don't know.
EDIT: Tried some older ones, nothing's worked yet. Also tried Rufus instead of the USB-SD Creator downloaded from the LibreELEC site (since sometimes the program writing to the USB is an issue, have never had success with balenaEtcher, but Rufus always works). Still didn't work.
EDIT 2: Tried the latest nightly (https://test.libreelec.tv/12.0/Generic/G…-248f521.img.gz) and nothing changed.
Why doesn't this work for me? I'm assuming it's an issue with syslinux? Ubuntu and other distros that use GRUB work fine for me...
The main reason I want to use LibreELEC on this laptop is that I want to use it as an HTPC, since I actually have it here. Naturally, with 16GB of RAM, four (counting USB-C) USB ports, battery backup to protect against power flickers or bad weather, and an internal SATA slot, it's beating the crud out of the nVidia Shield TV.
I have a much stronger laptop I use for personal use, I like to recycle old hardware when I can and using this laptop as an HTPC is how I'd like to repurpose it as I would get great use out of it.
Why LibreELEC specifically instead of Windows or Linux? LibreELEC can use the Amazon Fire Stick remote I have here. Windows and Linux distros can't. It syncs (it's recognized as "AR" in the respective Bluetooth menus) but no program recognizes it as an attached device. I don't know how LibreELEC does it, but it does. Works perfectly fine with it.
