Fresh Gentoo Install - Trouble with ALL bootloaders

Quote

Post by skips » Mon Mar 24, 2025 4:48 pm

Hello Gentoo Community,

I've been a gentoo user for at least the last 15 years, mainly on my home server environment. I have decided to upgrade my homelab server after 10 years of running (more or less) PC hardware and I purchased a used Dell R540 rack-mounted server with dual Xeon 6138 Gold CPUs.

I must say the gentoo handbook has become a wonderful document and following it with my fresh install was a bliss.

However, I cannot seem to get my system to boot - my server shows nothing else than "booting gentoo failed".

I have compiled my own kernel using gentoo-sources like I have been doing since my early days. My experience with "new" boot loaders have been very limited as I am still using lilo (with a GPT partition)

on my current operational machine.

On this new install I set my system to UEFI in the BIOS setting and tried grub, systemd-boot and EFI stub. The pattern is always the same: Once I reboot from the liveCD, booting my installation fails with "booting <label> failed".

I have installed gentoo on a 1TB NVMe module installed with a PCIe adapter.

Hoping for some hints how to solve this. I think the easiest is to use Grub going forward and make this work somehow.

From the top, I have created a GPT partition as per the handbook:

Code: Select all

Device            Start        End    Sectors   Size Type
/dev/nvme0n1p1     2048    2099199    2097152     1G EFI System
/dev/nvme0n1p2  2099200   69208063   67108864    32G Linux swap
/dev/nvme0n1p3 69208064 1953525134 1884317071 898.5G Linux root (x86-64)

The EFI partition is formatted with fat and the system partition is XFS-formatted.

installkernel is built with grub USE flag and all others have been disabled.

This is the output of "make install":

Welcome,

The initial message gave me impression that first stage boot loader (BIOS/UEFI) having problem locate boot device. So from your system setup were you able see those NVMe device(s)? maybe you need to enable/disable something.

Have you seen this? https://dl.dell.com/topicspdf/poweredge ... _en-us.pdf

Thanks for the hint. I triple checked my BIOS settings and they seem alright, e.g. regarding the NVMe module in non-RAID mode, etc.
The system seems to be able to "see" the module but fails to boot from it. This is the exact output during the boot attempt:

Code: Select all

Booting from gentoo
Boot failed: gentoo

Booting from Linux Boot Manager
Boot failed: Linux Boot Manager

I guess the second entry is from one of my earlier attempts with systemd-boot.

Could it be that my kernel is misconfigured? I kind of ruled this out before since it doesn't seem to load the kernel in the first place.
Any considerations regarding initramfs? Is there something wrong with my approach from my original post?

skips,

Those messages do not come from the kernel.

The boot sequence is
1. The EFI firmware loads an EFI compatible program of your choice. Often a boot loader but it can be the kernel too.
2. The boot loader does its thing, offers you a menu.
3. You select something to boot, the booot loader loads the kernel and optionally, one or more initramfs.
4. The boot loader exits by jumping to the kernel start address.
5. The kernel does it's initialisation, then mounts the root filesystem. This may be an initramfs.
6a. The initramfs executes its init script and drops you to a rescue shell it something goes wrong
6b Control is passed to /sbin/init to complete system startup.

It sounds like its not getting as far as step 2.

In the chroot, what does

Code: Select all

efibootmgr

tell?

Okay, this makes perfect sense to me.

efibootmgr provides this output:

Please show the content of /boot/grub/grub.cfg.

And also the output of:

Code: Select all

I think you need to use a simple way such in wiki https://wiki.gentoo.org/wiki/GRUB

add GRUB_PLATFORMS="efi-64" to make.conf
emerge grub with 'mount' flag
emerge os-prober (if you use other OS on ohters ssd)
create boot directory in root (I mean /)
grub-mkconfig -o /boot/grub/grub.cfg
emerge installkernell (I use solid kernel only, and I have grub emerged with grub flag only)
mount /efi
grub-install --efi-directory=/efi (sorry you did it already)

the last command should add a grub loader to /efi and gentoo boot element to your UEFI,

Code: Select all

kee /home/ed # efibootmgr | grep gentoo
Boot0000* gentoo        HD(1,GPT,abf721c9-36c7-423d-ab44-16b726c7e4a8,0x800,0x200000)/\EFI\gentoo\grubx64.efi

after that you can choose it in your BIOS, and after your 'make install' command new kernel should be added to /boot directory and grub config should update (installkernel and os-prober help with it) and you can see the same output

skips,

Code: Select all

Boot0005* gentoo        HD(1,GPT,faacf487-8301-44a7-80e6-3b121d89d23e,0x800,0x200000)/\EFI\gentoo\grubx64.efi

This says to load grubx64.efi from the ESP from the directory EFI/gentoo. The \ are correct in the path name above. Microsoft had a hand in writing the EFI specification.
It looks correct.

This goes on to load the file grub_stage2 (from memory) from /boot/grub/.
That in turn displays a menu for you to choose what to boot.
/boot can be the ESP.

Hence sMueggli asking for /boot/grub/grub.cfg, asit populates the boot menu.
If it never gets that far the error is with the grub build or install.

Along with /boot/grub/grub.cfg, tho output of

Code: Select all

 ls -l /boot

will be good, so we can see that the files listed in the menu actually exist.

emerge installkernell (I use solid kernel only, and I have grub emerged with grub flag only)
mount /efi
grub-install --efi-directory=/efi (sorry you did it already)

the last command should add a grub loader to /efi and gentoo boot element to your UEFI,

Code: Select all

after that you can choose it in your BIOS, and after your 'make install' command new kernel should be added to /boot directory and grub config should update (installkernel and os-prober help with it) and you can see the same output

        echo    'Loading initial ramdisk ...'
        initrd  /EFI/Gentoo/intel-uc.img
}

Tries to load a a kernel from /EFI/Gentoo/vmlinuz-6.12.16-gentoo.efi
Thats not wrong but its an efi stub kernel.
There is no initrd to load kernel modules from. That's OK if you made your own kernel.
We don't know that EFI/Gentoo/ exists and is populated. We haven't asked yet.
Anyway, that's doing it the hard way, so we can come back to that.

Its not until we get into the advanced menu that we get

Code: Select all

menuentry 'Gentoo GNU/Linux, with Linux 6.12.16-gentoo' --class gentoo  --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-6.12.16-gentoo-advanced-bce381c4-6226-467c-954b-c9e6314f8572' {
                load_video
                if [ "x$grub_platform" = xefi ]; then
                        set gfxpayload=keep
                fi
                insmod gzio
                insmod part_gpt
                insmod xfs
                search --no-floppy --fs-uuid --set=root bce381c4-6226-467c-954b-c9e6314f8572
                echo    'Loading Linux 6.12.16-gentoo ...'
                linux   /boot/vmlinuz-6.12.16-gentoo root=UUID=bce381c4-6226-467c-954b-c9e6314f8572 ro
                echo    'Loading initial ramdisk ...'
                initrd  /boot/intel-uc.img /boot/initramfs-6.12.16-gentoo.img
        }

Which is much more like we expect and all the bits are in /boot to support.

Do you get a grub menu at all?
I think that's the 5th entry in the advanced menu. The first 4 all want various efi stub kernels.
Does the 5th entry in the advanced menu boot?

Regards,

grub.cfg looks like wrong, so after 'make install' command grub.cfg was regenerated or not?

in your 'ls -l /boot' output I see *.old after kernel update, but there doesn't exists grub.cfg~ - previous config
install kernel had to run grub config update as

Code: Select all

grub-mkconfig -o /boot/grub/grub.cfg

It looks like the gentoo entry in efibootmgr is correct; however, there is the old systemd-boot entry and some "Hard drive C:" options. Is it possible to regenerate this boot manager list and start over from scratch?

To your point, grub never loads and I cannot get passed the failed boot message as listed above.

skips,

Since grub never loads the content of grub.cfg has no bearing on the problem yet.

You can use efibootmgr to remove entries and reorder them.
That won't help either as your gentoo entry is first in the list.

It has to be the way grub is built or installed.
Please post the output of emerge --info.
You should have an entry for grub there.

I'm a syslinux user but that's not a reccomendation.
The information on it is both sparse and conflicting.

Regards,

NeddySeagoon

Computer users fall into two groups:-
those that do backups
those that have never had a hard drive fail.

I still believe your first stage boot load (UEFI) having trouble finding boot device.

Can you share fdisk -l /dev/nvme0n1 or blkid, so we can see what is UUID for the device.

The last output of grub.cfg looks good.

Does the firmware have a "Secure Boot" configuration? And if so, is Secure Boot disabled?

Maybe it is a problem with the PCIe adapter? Is it possible to use another slot? Is the NVME device ready when the firmware tries to load the binary?

Is your problem similar to https://www.dell.com/community/en/conve ... 2df9bea0ec?

I think we are getting closer. It's great that we can rule out (at least major) configuration issues. I'll try using another slot and/or adapter later tonight.

For now, here's fdisk -l:

Your disk identifier is "22815EBB-883E-4203-954F-FEB71745D890" whereas your uefi boot string use "faacf487-8301-44a7-80e6-3b121d89d23e" I suspect that could be a issue.

I am not UEFI user and I don't have existing system to test. but if you can update your uefi boot entry to use the "22815EBB-883E-4203-954F-FEB71745D890" to see if that help.

Alternative, if that does not help, I suspect your system UEFI firmware may not recognize the NVMe on the PCIe adapter as "disk" therefor the "HD(1,GPT..." is not working. so it is possible you need to use "PciRoot(0x0)/Pci(0x1C,0x0)/Pci(0x0,0x0)/NVMe(0x1,faacf487-8301-44a7-80e6-3b121d89d23e,0x800,0x200000)" as boot entry string. Please note those PciXXX number may need to change depend on how you PCIe card plug in on your board. you can use lspci to list them. However I am don't know how to identify PCI list output, but I suggest you still try to list them here, so someone can help and identify the PCI path.

Another possibility is that in system setup (F2) SATA Settings details/Embedded SATA you need to set right type "AHCI Mode" and NVMe Settings details/NVMe Mode type is " Non RAID"

my primary thinking is that your board UEFI not able to find the device. I don't know if you have way to verify that at UEFI level you can actually detect that NVMe device.

Maybe you can use Boot Manager main menu/System Utilities that enable System Utilities and use One-shot UEFI boot menu/System Utilities to lunch Launch Diagnostics to see if there any tool to help you identify and verify UEFI know something about the NVMe device.

The output of efiboomgr references the partition UUID, and not the disk UUID. The EFI-System-Partition has to be a partition.

.

OK, we should still review if the partition UUID match or not.

Explain why I think it is disk UUID wrote: I am just reading UEFI specification v2.10 :: Protocols Device Path Protocol :: 10.3.5.1. Hard Drive :: Table 10.54 Hard Drive Media Device Path. In that table The forth(4) field is already specific partition number (in reference to "HD(1,GPT,...)" That "1" is refer to partition 1, so that following UUID would be a disk UUID in the event where a system have multiple bookable "disk"s a way let UEFI firmware to identify which "disk" for boot.

sMueggli,

I have confirmed that UUID field indeed refer to partition UUID from the specification.

Boot Manager :: Firmware Boot Manager :: Boot Manager Programming :: Load Option Processing wrote:The boot manager must also support booting from a short-form device path that starts with the first element being a hard drive media device path (Hard Drive Media Device Path ). The boot manager must use the GUID or signature and partition number in the hard drive device path to match it to a device in the system. If the drive supports the GPT partitioning scheme the GUID in the hard drive media device path is compared with the UniquePartitionGuid field of the GUID Partition Entry ( GPT Partition Entry ). If the drive supports the PC-AT MBR scheme the signature in the hard drive media device path is compared with the UniqueMBRSignature in the Legacy Master Boot Record ( Legacy MBR ). If a signature match is made, then the partition number must also be matched. The hard drive device path can be appended to the matching hardware device path and normal boot behavior can then be used. If more than one device matches the hard drive device path, the boot manager will pick one arbitrarily. Thus the operating system must ensure the uniqueness of the signatures on hard drives to guarantee deterministic boot behavior.

It is said "If a signature match is made, then the partition number must also be matched"

whereas the GUID Partition Entry specify "UniquePartitionGUID"

GUID that is unique for every partition entry. Every partition ever created will have a unique GUID. This GUID must be assigned when the GPT Partition Entry is created. The GPT Partition Entry is created whenever the NumberOfPa rtitionEntries in the GPT Header is increased to include a larger range of addresses.

Thanks for clarifying. I checked the partition IDs and the EFI partition matches up with the boot entry.

Code: Select all

/dev/sr0: BLOCK_SIZE="2048" UUID="2025-03-23-18-17-27-00" LABEL="Gentoo-amd64-20250323" TYPE="iso9660" PTTYPE="PMBR"
/dev/nvme0n1p3: UUID="bce381c4-6226-467c-954b-c9e6314f8572" BLOCK_SIZE="512" TYPE="xfs" PARTUUID="68bbd7e7-c72c-4f78-b1d6-02c30175ba48"
/dev/nvme0n1p1: LABEL_FATBOOT="efi-boot" LABEL="efi-boot" UUID="8370-A3D4" BLOCK_SIZE="512" TYPE="vfat" PARTUUID="faacf487-8301-44a7-80e6-3b121d89d23e"
/dev/nvme0n1p2: UUID="1db07912-2968-4868-b09d-c0970c27fd0a" TYPE="swap" PARTUUID="bdd39b2f-5b5f-4abc-8e74-dc787e908421"

I'm seriously puzzled.

Quick update on this: I swapped the PCIe adapter for another module and used it in another slot.
Sadly, the issue prevails. I checked disk and partition UUIDs remained unchanged. Could it be that my NVMe module does not work in this setup?

Did you try to use One-shot UEFI boot menu/System Utilities to lunch Launch Diagnostics to see if NVMe device visible at UEFI firmware boot manager?
