 Posted: Thu Jan 09, 2025 9:20 am Post subject: The gentoo system could not be started |
 |
|
Hi, I just installed the gentoo system, but when I reboot, I found that I could not enter the system, only the following information was prompted. And I installed a binary kernel. Could anyone give me some advice? I will provide more information if necessary. Thanks sincerely.
| Code: | Loading Linux 6.6.67-gentoo-dist...
Loading initial ramdisk...
error: you need to load the kernel first.

The backup GPT table is corrupt, but the primary appears OK, so that will be used.

cien,
| Code: | | Loading Linux 6.6.67-gentoo-dist... |
is some text of your making printed by grub, just before it loads the kernel.
Likewise | Code: | | Loading initial ramdisk... |
just before the initrd is loaded.
Two questions.
What is the output of It should list all of you installed kernels and initrd/iniramfs files.
It may be /efi rather that /boot on your install.
What is the content of grub.cfg?
That will be in /boot/grub/... or /efi/grub/
It looks like loading the kernel failed for some reason.

IIUC that sequence of messages means that GRUB read and loaded the initramfs, but couldn't do so for the kernel One possible cause that Google found me is that you are using secure boot but something is wrong - so if you did, try turning it off in BIOS, and see if that gets you booting.

To be honest, I don't know if it's because I'm confused with uefi or boot, I don't know where to identify them. |

Thanks for your reply, I checked and the secure boot is disable, legacy support is enable, and fast boot is disable. |

cien,
That's all self consistent. Good.
What does | Code: | | file /boot/kernel-6.6.67-gentoo-dist |
say about your kernel?
