No boot options in Grub/Kernel option unavailable

[andreas_pan]

Hello,

There’s no option to select a kernel and enter the system upon boot. I can only choose metest.

When I go into Grub it says that it hasn’t loaded a kernel (or something along those lines).

Also, when I go into uefi, I don’t see the vmlinuz line (apologies for the inaccuracy).

I was trying to remove the ghost kernels following the instructions on this forum named ‘how-to-remove-a-ghost-kernel’.

After I was finished, I ran:

sudo ls /etc/mkinitcpio.d/*.preset

The result was:

etc/mkinitcpio.d/linux510.preset

I also ran:

sudo ls /boot/*

But I don’t remember the output.

Hello,

Start from here

Error: file '/boot/vmlinuz-5.12-X86-64' not found you need to load the kernel first

Typical n00b mistake. What you should have done was let the update finish, because it’s a very CPU-intensive and I/O-intensive procedure, and that’s why the system appeared unresponsive. Yes, and that’s because the initramfs is only generated at the end of the update procedure, and only then is GRUB updated as well. Okay, boot up from the Manjaro CD/USB ─ any recent one will do; it doesn’t have to be the latest ─ in live mode, and then open up a terminal window. In this…

Hi there,

Thanks for the reply. So, here is the output:

I followed the instructions and then restarted the computer but the problem persisted: the only boot option was to go into memtest.

[bogdancovaciu]

Just my guess … you still have Fast Boot enabled in BIOS and also … not sure, but you might did the update from Live Media in the chroot of the installed file system, but the kernel install probably you did it outside the chroot …
If you get stull like

@andreas_pan

local (0.6.7-2) is newer than extra (0.6.6-11)

use

sudo pacman -Syyuu

[stephane]

also theses point to see , with chroot

ls /etc/mkinitcpio.d/*.preset
ls /boot/
ls /lib/modules/*

There’s no option to select a kernel and enter the system upon boot. I can only choose metest.

When I go into Grub it says that it hasn’t loaded a kernel (or something along those lines).

Also, when I go into uefi, I don’t see the vmlinuz line (apologies for the inaccuracy).

If you see memtest as a boot option, then your system is not booting up in native UEFI mode. memtest86 only runs with legacy BIOS boot, and if the system is set to boot in UEFI mode, then the memtest86 entry will not be shown in the GRUB menu; instead you will then see an entry to enter the UEFI settings.

Installing the boot loader in legacy mode is also different from installing it in UEFI mode. In UEFI mode, the boot loader is an EFI executable stored in the EFI/boot directory of the EFI system partition. In legacy BIOS mode, the boot loader is a 16-bit real-mode executable stored in the master boot record.

If you mix up both methods of booting, trouble will arise.

So here’s the output:

> [manjaro /]# ls /etc/mkinitcpio.d/*.preset
> /etc/mkinitcpio.d/linux515.preset
> [manjaro /]# ls /boot/
> grub                                intel-ucode.img       memtest86+

> [manjaro /]# ls /bin/modules/
> ls: cannot access '/bin/modules/': No such file or directory

[andreas_pan]

I still get the following:

[manjaro /]# sudo update-grub

[andreas_pan]

I do run the legacy mode (I tried uploading two pictures to show but I’m not allowed to upload pictures on a post).

[stephane]

can you try , with chroot

pacman -Syy
pacman -S linux515

[andreas_pan]

I think it worked. This is the output:

[manjaro@manjaro ~]$ sudo su -
[manjaro ~]# manjaro-chroot -a

I’ll try rebooting and will let you know.

Worked like a charm. Thank you guys!
