GRUB fails to install

[Karthikeyan]

I was installing the latest Peppermint OS 6 side by side of Windows 8. At the end when the GRUB was about to be installed, a failure message was saying "grub-efi-amd64-signed failed to install into /target/". Without GRUB I couldn't boot into POS6.

I enabled secure boot and entered peppermint and ended up in this screen!




Ask for any missing details, I will provide. Please help to resolve this issue.

PS:My problem is very similar to http://forum.peppermintos.com/index.php/topic,1904.0.html, but the user didnt mention GRUB installation failure nor could I understand the solution provided. Please help.

Can you boot to the LiveCD/LiveUSB, open a terminal (Ctrl+Alt+T)  and post the output from running this command:

Code: [Select]

sudo fdisk -l

Code: [Select]

peppermint@peppermint ~ $ sudo fdisk -l

Is there anything on the 500GB HDD that you need to keep .. or can it be completely formatted ?

[Karthikeyan]

Oh I forgot the most important...I am installing along side Windows 8.

[PCNetSpec]

I take it Windows is preinstalled and you don't have the installation media ?

[Karthikeyan]

Installation media of what? I dont know what an installation media is in the first place...

[PCNetSpec]

media = disk or whatever media the installation came on

usually a DVD, but could be a USB stick

So do you have the installation media for reinstalling Win 8 ?

[Karthikeyan]

No not a media for reinstalling Windows 8. Does a recovery drive count as a installation media? Because I have one. And are you hinting at erasing Windows and reinstalling it?! 

[PCNetSpec]

Formatting the drive away from a GPT partition table and reinstalling Windows 8 in legacy BIOS mode would certainly have been the easiest option if it were possible.

let's have a look at your GPT disks structure

can you boot to the LiveCD/LiveUSB .. connect to the internet, and install gdisk:

Code: [Select]

sudo apt-get install gdiskthen post back here the output from:

Code: [Select]

sudo gdisk -l /dev/sdaand

Code: [Select]

uname -a

Hi Karthikeyan, how's it going?  For future reference could you please encapsulate terminal outputs with the # code function.  It preserves the original format.  This function is located above the Embarrassed emoticon in the forum editor.  I've done this for you this time  - many thanks  !

[PCNetSpec]

I don't think there's any SAFE way to do this (but I'm still reading).

If the machine won't install Peppermint 6 64bit in EUFI mode, then to install GRUB on a drive with a GPT partition table requires an EF02 bios_boot partition to be present on the drive.

I'm unsure how to achieve this without destroying Windows or Windows EFI booting .. or if the bios_boot partition can go anywhere as long as it's flagged correctly.

I'm trying to figure it out.


Did you try installing the 64bit version in UEFI mode ?
(ie. NOT in legacy BIOS mode, but with secureboot disabled)

Are you able to boot a Peppermint 6 64bit LiveCD/LiveUSB in UEFI mode (with secure boot disable) ?

If so, have you tried running boot-repair:
https://help.ubuntu.com/community/Boot-Repair
whilst in UEFI mode (with secure boot disabled) ?

[Karthikeyan]

Yes installed the 64 bit Perppermint OS 6 in UEFI mode.
Yes can boot a LiveUSB without secure boot.

Currently running codes from the Boot Repair link you gave. Will update some time

Please do let us know if Boot-Repair helps.
