[SOLVED] BIOS doesn't detect GRUB

[Torpus]

I know this is kind of odd, but despite installing GRUB and configuring it "appropriately" it is still not working at all (laptop goes to BIOS menu instead of GRUB after turning it on)

I'm installing Gentoo with chroot

[GDH-gentoo]

What does "not shown in BIOS" mean?

GDH-gentoo,

It means that if you turn on the laptop without a LiveUSB, it goes directly to the BIOS menu after the boot logo. And when you go to the boot options you find none. IDK how is this case called appropriately

Torpus,

The term BIOS is badly defined these days.

Do you really mean BIOS almost as IBM wrote it, 40 years ago :)
Or is it EFI Firmware in legacy or BIOS compatibility mode, or is it EFI Firmware in EFI mode with secure boot disabled?

It matters as grub is installed differently in each case.

NeddySeagoon,

It's Legacy BIOS with EFI support!

There's no secure boot there, and I installed GRUB for Legacy and without EFI (there's no /boot/grub/efi directory and it never existed in previous failed installations of Gentoo). And just like in my previous Gentoo installation attempts, the disk is in the GPT partition table.

pietinger,

I've no UEFI at all (but only EFI support, in this case there's no filesystem for it nor is it installed for GRUB. I know I got this midrange laptop 3 years ago brand new and has absolutely no UEFI)

Thanks for all the info though. I do have a /boot partition with a fat32 filesystem and a 2MB unformatted partition which is necessary to make GRUB work since it's BIOS with GPT

Guess what, the /sys/ folder is empty!!

Also parted shows this about my disk:

pietinger,

I had "no error" but with this:

[pietinger]

Please check your BIOS settings. Do you have something like "SecureBoot" ? If yes, THEN there must be an option named "CSM mode" or "legacy mode". Is it enabled or disabled ?

[Torpus]

pietinger,

Looking back at BIOS settings I find Secure Boot Control disabled. In the boot section there is "Fast Boot" which is enabled and "CSM Support" which is disabled.

Am I supposed to enable CSM?

pietinger,

Well, I think enabling CSM did nothing.

I tried re-installing GRUB after enabling CSM, it gave the exact same output as before with the "No such device" spams.

And by going to BIOS settings, the Gentoo boot option hadn't shown up yet.

Again, my computer has ABSOLUTELY no UEFI. It is Legacy BIOS and has some EFI support which is basically useless for my installation.

Maybe some expert like Neddy could know how to solve this...

pietinger,

Thanks for clarifying me this. I don't want Secure Boot since it makes problems with virtual machines and stuff, I just want GRUB to work.

Now you just made me confused as hell: How am I having UEFI when I had before GRUB working well without any /boot/grub/efi directory??

If you say it is a UEFI capable system, then of course it is. For the UEFI bloat is harmless, but it's bloat to my originally Legacy BIOS system!

I think someone else who knows about Legacy BIOS can figure this out.

Maybe the "No such device" messages can give a clue..

edit: Aah wait... I probably had to put GRUB_PLATFORMS="efi-64" BEFORE emerging GRUB since I have a GPT partition table

I'll be back in a sec...

No, this just made it even worse, back to GRUB_PLATFORMS="pc" as it originally was in previous installs.

Torpus,

please wait ...

What you have tried now is to install an UEFI boot ... => grub-install --target=x86_64-efi ... this is something you dont want ...

GRUB_PLATFORMS="pc" is correct for a CSM boot ...

... you must only enable CSM mode in BIOS ... then boot WITH this option into our GentooInstallCD ... CHROOT into your gentoo installation (link I gave) ... install grub with

"grub-install /dev/nvme0n1"

There should be no errors. If so, please tell us (and wait)

Torpus,

I think I have edited mistakenly your post

I could reach it with my browser go back. Please allow me to paste it here:

pietinger,

Yep that was it   I had GRUB_PLATFORMS="pc" and then totally neglected the EFI arguments when installing GRUB as a bootloader.

Really sometimes I get too dumb!! 

But...

So, as if you're telling me I had to wipe the entire NVMe disk and leave nothing from it and reinstall Gentoo from scratch AGAIN. I do not wish that as I've spent days and days compiling my apps I wanted to use.

Your BIOS does not support booting from this type of media
If nvme media works through pci interface, it is not a type of odd in this way
