Iam trying to install Ubuntu on my Acer-Laptop.

This laptop normally runs with Windows 10, but I chose the option to remove Windows from my disk, which was offered by the Ubuntu-Installer.

I can successfully install Ubuntu from my USB-Stick. When the installation proccess is done, Iam getting the expected message that everything is fine and I should now reboot my computer.

However, when I now reebot my Computer, Iam getting the following error:

No Bootable Device

My BIOS boot-options are the following:

Boot Mode: UEFI
Secure Boot: Enabled
Boot priority order:

1. HDD0: LIETON CV3-8D256
2. HDD1: WDC WD10SPCK-21KHST0
...

Ubuntu should be installed on both disks, since I tried both of them via Ubuntu-Installer.

I tried the following things:

  • Using boot-repair, as its described in this thread (german language)
  • Installing Ubuntu Version 18.04 again multiple times
  • Installing Ubuntu Version 17.04 multiple times
  • Downloaded mand different images from different websites and reflashed my USB-Sticks multiple times using Rufus

but nothing worked.

I want to say that I do NOT care about the data on my disks. I got multiple backups and everything on them can be destroyed if needed.

I also want to say that I do nearly know nothing about how Bootloaders and all this stuff works, Iam normally used to just plug my stick in, install the OS and everything works fine, but it seems like the ouput of the following commands may be interesting for you, since those have been requested on other forums:

sudo parted -l:

    All Acer require you to set UEFI password and enable "trust" on the grub/ubuntu .efi boot files in the ESP from within UEFI. http://askubuntu.com/questions/627416/acer-aspire-e15-will-not-dual-boot & https://ubuntuforums.org/showthread.php?t=2297947&p=13369742#post13369742 & https://ubuntuforums.org/showthread.php?t=2358003 – oldfred May 03 '18 at 03:33

I believe this https://help.ubuntu.com/community/UEFI article holds all the information you need to complete a successful setup.

  • Please note that at this moment your install and your device are both configured (hypothetically) for UEFI. The article has info for repairing installs that go wrong. – M K May 03 '18 at 00:34

And as always, a couple minutes after I ask a question, I find a solution (btw. my internet-connection went down, thats why Iam asnwering that late.):

Open your BIOS (In my case press F2 while booting)

Got to the Security-Tab and look for Select an UEFI file as trusted for executing. If its disabled, like in my case, just create a security password.

select an UEFI-File as trusted and reboot.
