[SOLVED] Unable to install Kubuntu 14.04.1 LTS on UEFI system.

americast · 02-17-2015, 11:06 AM

Hi all,
I am trying to install Kubuntu 14.04.1 LTS as the second operating system on an HP Probook (powered by intel core i3). I have disabled secureboot and fastboot from UEFI/BIOS settings. I had created a live image of 'kubuntu-14.04.1-desktop-i386.iso' on a pendrive. The installation went fine. But, the system does not boot into grub. It only boots Windows 8.1 (which came preinstalled).
I had applied the command

Code:

bcdedit /set "{bootmgr}" path \EFI\ubuntu\grubx64.efi

in command prompt but it bore no fruit. I had created the live usb using Universal USB installer. Any help would be appreciated.

Gramercy...

I think you have to use the 64 bit version for uefi

I just installed Debian on a UEFI system by changing the boot order in BIOS to boot from Debian's UEFI partition then running update-grub as root -- that added Windows's boot loader to GRUB's menu and now I can dual boot.

Not all uefi systems seem to be standard.

As you mention that the install went OK but then not booting. We need to get more info as to what you see. Why do you say it isn't booting to grub?

Looks like you are trying to chain load grub too. Did you do that originally?

Thanx to you all...

The 64 bit version is called "kubuntu-14.04.1-desktop-amd64.iso". I guessed it was for systems having AMD processor. Will it work on Intel 64bit?

I mean, grub does not appear during boot. It directly goes into Windows.

I don't see any such option in BIOS.

Again gramercy...

Yes, AMD64 is the name of the architecture as it was invented by AMD and is cross licensed to Intel in exchange for use of the i386 (32 bit) architecture (put simply).

Then the install may not have been correct or, as mentioned, you may need the 64 bit version. Did you use automatic or manual partitioning and were you prompted to create a UEFI partition? You may not find it as easy as I did as I understand that some machines are easier to work with than others but I wouldn't start complicating things and messing with third party tolls until you know you have to.
This talks about some UEFI installation tips:

I'll try to dig out the page I found which started me on my way also.

Tried with amd64. The issue remains the same- installation goes successful but it does boots to Windows when installation process requests a restart. Instead of the installation continuing, Windows comes up.

Here's a screenshot of my disk setup configuration: https://www.dropbox.com/s/1t3sy0mid2...shot1.png?dl=0

I would like to stress on the fact that Ubuntu had requested me to create the biosgrub partition (without mentioning the size) when I had clicked on "Install Now".

I can't tell whether that's completely right but it looks like it is. Whne you go into BIOS do you still only see Windows as a choice of partitions to boot from? Is there an option in BIOS to ask it to search for bootable partitions?

Try using the Kubuntu 14.04 64 bit version with these instructions:

americast · 04-05-2015, 11:45 AM

I tried following the instructions on this website: https://sites.google.com/site/easylinuxtipsproject/6

The issue is I get an error when I try to mount the EFI partition, which I guess is sda2 (see image here: https://www.dropbox.com/s/1t3sy0mid2...shot1.png?dl=0). Here's what I get:

Code:

sudo mount /dev/sda2 /mnt/boot/efi
mount: mount point /mnt/boot/efi does not exist

Also, when I try to reinstall grub, I get an error:

Code:

sudo grub-install /dev/sda
Installing for i386-pc platform.
grub-install: error: failed to get canonical path of `/cow'.

Gramercy...

colorpurple21859 · 04-05-2015, 01:47 PM

Code:

sudo mkdir /mnt/boot/efi
sudo mount /dev/sda2 /mnt/boot/efi

may have to edit your /etc/fstab to add /dev/sda2

Are sure your booting in efi mode with kubuntu or into windows in efi mode?

beachboy2 · 04-05-2015, 04:25 PM

americast,

I am assuming that your personal data has already been backed up to an external drive or similar.

From your Dropbox snapshot, your Windows FAT32 (boot) partition is /dev/sda2 and your Kubuntu system installation (ext4) partition is /dev/sda8 (NOT sda2).

This link shows how to correct the situation using chroot, but do make sure that you select sda8:

http://askubuntu.com/questions/88384...alling-windows

Here's how:

1. Boot from the live Ubuntu DVD, select "Try Kubuntu" and access the Terminal.

2. Determine the partition number of your main partition (sda8)

3. Mount your partition:

Code:

sudo mount /dev/sda8 /mnt

Then carry out instructions 4. to 9.

Did exactly as you said. Still boots into Windows. Did not get any errors during installation.

americast,

Well at least there is some improvement with no errors being reported.

I think it is just a matter of correcting Grub.

This procedure is similar to what you have already done but with certain variations:

Timothy Miller · 04-06-2015, 11:40 AM

Just a quick question learned by having the same issue. Do you have anything in the firmware something similar to "allow legacy compatibility"? I had something like that which required being turned off to prompt the installer to actually INSTALL grub-efi, otherwise it wouldn't install grub.
