I went and bought myself an external CD-ROM.
Booted, chrooted and fixed "installkernel".
Now I don't remember if the GRUB also was updated, but I don't think so.
However - just in case I want to reinstall it.
But the HB is now contains too much information and I don't remember what/how the GRUB was installed.
Is there a way to find out?
I think I used EFI with GPT label but I'm not sure...
Thank you. |

This provides some insight as to how grub was installed. |

Hi,
This weird.
I also have GPT as label on the fdisk output and x86_64-efi directory in /boot/grub.
But trying to install it as EFI results in an error.
Thank you. |

| What is the command you used to attempt to install grub? And, do you have GRUB_PLATFORMS="efi-64" in /etc/portage/make.conf? |

Hi,
The commands are:
| Code: |
grub-install /dev/sda
you'd grub-install --efi-directory=/boot
you'd grub-install --target x86_64-efi --efi-directory=/boot
|
And yes - I do have this line...
Thank you. |

This line from your mount command output | Code: | | /dev/sda1 on /boot type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro) |
would indicate that grub-install /dev/sda should be grub-install /dev/sda1
| Code: | you'd grub-install --efi-directory=/boot
you'd grub-install --target x86_64-efi --efi-directory=/boot |
The FX-8350 computer is set up with the currently suggested scheme using an /efi directory. It was | Code: | | grub-install --target x86_64-efi --efi-directory=/efi |
and that is mounted on the 1st partition. |

Hi,
does not yield anything...
Running:
| Code: |
grub-install /dev/sda1
|
or
| Code: |
grub-install --efi-directory=/efi
|
both rsults in the:
| Quote: |
[/usr/lib/grub/i386-pc/modinfo.sh doesn't exist. Please specify --target or --directory
|
Now this:
| Code: |
grub-install --target x86_64-efi --efi-directory=/efi
|
results in:
| Quote: |
Installing for x86_64-efi platform.
grub-install:error: Failed to get canonicl path for /efi
|
Thank you. |

Let's stop guessing your setup. Post the outputs of:
| Code: | $ lsblk -o name,mountpoints,partlabel,parttype
$ ls /sys/firmware |

Hi,
The output is:
| Code: |
loop0
sda
|----------sda1/boot c12a7328-f81f-11d2-ba4b-00a0c93ec93b
|---------- sda2 0657fd6d-a4ab-43c4-84e5-0933c84b4f4f
|---------- sda3 / 0fc63daf-8483-4772-8e79-3d69d8477dc4
|
All 3 are directories...
Thank you. |

Alright, disk /dev/sda has a GUID partition table (GPT), partition 1 is marked as the EFI System Partition (ESP) and is mounted at /boot, so likely this computer supports UEFI, and your normal GRUB update command should be grub-install --efi-directory=/boot. However:
your rescue medium has not booted in UEFI mode, or otherwise there would be another directory named efi. That's why you are having trouble, particularly with updating EFI variables:
| ONEEYEMAN wrote: | Installing for x86_64-efi platform.
EFI variables are not supported on this system.
EFI variables are not supported on this system.
grub-install: error: efibootmgrfailed to register the boot entry: No such file or directory. |
It may not matter, though, because you are using GRUB, so the pathname in the ESP's filesystem of the executable that the firmware should run doesn't really change.
Given all of this, with /dev/sda1 mounted, try this:
| Code: | # rm -r /boot/grub/x86_64-efi # Wipe all old GRUB modules
# grub-install --no-nvram --target=x86_64-efi --efi-directory=/boot # This one time only
# grub-mkconfig -o /boot/grub/grub.cfg |
And if all commands succeeded, try rebooting the computer.

I am interested as to why it is looking for the modinfo.sh file here; /usr/lib/grub/i386-pc/modinfo.sh
The modinfo.sh file on my amd64 machines using UEFI are here; /usr/lib/grub/x86_64-efi/modinfo.sh
The wiki.gentoo.org grub entry says; | Quote: | | grub-install accepts a --target option to set the CPU architecture and system platform. If unspecified, grub-install will attempt to guess the correct values; on an amd64/x86 system in BIOS mode it will use i386-pc by default and in conjunction with a GUID partition table (GPT) a "BIOS boot partition" will be automatically used when present. |
I'm guessing at some time your system was booted in the BIOS mode, not UEFI, and grub guessed i386-pc for you.
Is your pc actually booting into UEFI mode? or BIOS mode?

Because the rescue medium did not boot in UEFI mode, so grub-install without a --target option autodetects the target as i386-pc, i.e BIOS, and tries to copy the BIOS variant of its modules, which are expected to be in /usr/lib/grub/i386-pc.

GDH-gentoo,
Should I back-up the content of the folder or just delete it?
Thank you. |

You can back it up for safety if you want to. Just make sure that it is empty or removed before grub-install, and that it has been repopulated after.
