Thank you for taking the time to report this bug and helping to make Ubuntu better.

This is a support comment & suggestion only. Is there a reason you didn't use the latest 18.04.3 which uses the HWE stack and thus has later kernel, modules & X support. If you didn't want the hardware enablement stack to be used, fair enough.

I didn't see a glaring issue on why you got your errors

but in your case I'd try the later Ubuntu 18.04.3 LTS which uses HWE (https://wiki.ubuntu.com/Kernel/LTSEnablementStack)

Hi Chris,Thank you for writing.Actually I am struggling to make my HP Envy laptop, dual boot with Ubuntu since quite a few days.Initially I tried installing latest 18.04.3 using live USB; my installation went through however windows 10 started booting by default and there was no change in behaviour even after disabling secure boot. Over the period of time I realized that it has something to do with GRUB installation as during booting I was not able to see GRUB coming into action.While I was still trying to find a resolution of this issue, my live USB booting started giving me errors saying &quot;EFI boot failed&quot; and again I was clueless. Meanwhile, I found this link:https://www.lifewire.com/fix-uefi-bootloader-issues-when-dual-booting-2200655which I thought was worth trying, so I tried installing Ubuntu again from already available USB stick which was smaller in size and it was already having that older Ubuntu image and that is where I landed in this error.By the way, following the link above when I tried using efibootmgr command after booting from older version of live usb stick, I was surprised to see that &quot;Ubuntu&quot; was missing there in list. Now, I am back to the same position and thinking to start the process all over again!I would highly appreciate any suggestions in this regards.Thanks,Shrenik.From: Chris Guiver &lt;<email address hidden>&gt;Sent: Wed, 04 Dec 2019 08:45:39To: <email address hidden>: [Bug 1855004] Grub install failed and installer crashedThank you for taking the time to report this bug and helping to makeUbuntu better.This is a support comment &amp; suggestion only. &nbsp;Is there a reason youdidn&#39;t use the latest 18.04.3 which uses the HWE stack and thus haslater kernel, modules &amp; X support. &nbsp;If you didn&#39;t want the hardwareenablement stack to be used, fair enough.I didn&#39;t see a glaring issue on why you got your errorsDec &nbsp;3 20:07:28 ubuntu ureadahead[1063]: ureadahead:/usr/lib/x86_64-linux-gnu/gconv/gconv-modules.cache: Error retrieving chunk extents: Operation not supportedDec &nbsp;3 20:07:28 ubuntu ureadahead[1063]: ureadahead:/usr/lib/ibus/ibus-engine-simple: Error retrieving chunk extents: Operation not supported..Dec &nbsp;3 20:07:28 ubuntu ureadahead[1063]: ureadahead:/etc/sane.d/epsonds.conf: Error retrieving chunk extents: Operation not supportedDec &nbsp;3 20:07:28 ubuntu ureadahead[1063]: ureadahead:/usr/bin/unsquashfs: Error retrieving chunk extents: Operation not supportedbut in your case I&#39;d try the later Ubuntu 18.04.3 LTS which uses HWE(https://wiki.ubuntu.com/Kernel/LTSEnablementStack)--You received this bug notification because you are subscribed to the bugreport.https://bugs.launchpad.net/bugs/1855004Title:&nbsp;Grub install failed and installer crashedStatus in grub-installer package in Ubuntu:&nbsp;NewBug description:&nbsp;On a pre-installed windows 10 HP laptop, Grub installation failed and&nbsp;installer crashed.&nbsp;ProblemType: Bug&nbsp;DistroRelease: Ubuntu 18.04&nbsp;Package: ubiquity 18.04.14.6&nbsp;ProcVersionSignature: Ubuntu 4.15.0-29.31-generic 4.15.18&nbsp;Uname: Linux 4.15.0-29-generic x86_64&nbsp;ApportVersion: 2.20.9-0ubuntu7....
