Missing boot option on startup

[mdooley]

That's what I would have done. I'm going to research the EFI business and see what I get. This can be solved!

Edit: Dang! This is going to be a bit of work. We've run into (I think) the Acer BIOS limitations. For starters, see this -

https://community.acer.com/en/discussion/492267/acer-es1-432-no-uefi-or-legacy-option/p2

I'll keep on this, but unless someone else chimes in first, I may not get you the best resolution for your problem within the next four hours. Hang tight and I'll see what I can come up with.

Edit2: See - system installation - Unable to install Ubuntu on Acer Aspire ES1-533 - Ask Ubuntu and go down to the second answer that begins with:

"The problem can be solved as follows:

1. Boot Ubuntu Live DVD/USB in testing mode and open terminal

2. Run installation process without installing bootloader by:

sudo ubiquity -b "

This might help you out. Good luck Russell.

There is a link to a very nice page on managing EFI boot loaders - Managing EFI Boot Loaders for Linux

Edit3: Searching our forum, I found this - Ubuntu 16 MATE - UEFI - no bootable medium after install - #3 by Ciprian_Cucu which kind of sounds like your first request for help. The Askubuntu page i linked to in the 2nd edit has links to other pages that explore the EFI business.

It would be nice if someone personally experienced with an Acer EFI install would speak up as I have no personal knowledge/experience of this matter. Sigh...

Install UM with UEFI or Legacy mode?

With my computer changing the boot order requires a UEFI password. Once the password is set, I can Disable UEFI Secure Boot (But it works fine with the secure boot on), and change the boot order to boot from DVD Drive and USB Devices first. For some reason the settings refused to save if i didn’t create a UEFI password. After installation I go back into UEFI and set the OS Boot Order to boot from Ubuntu first rather than windows first.

Hi, if you don’t have a UEFI based system (Windows 8 or 10) installed, there isn’t any real need for it as you are most likely already booting from “Legacy BIOS” and UEFI is indeed switched off!. So Ubuntu doesn’t really need to worry about whether or not the PC is UEFI compliant!. Case when Ubuntu must be installed in UEFI mode Having a PC with UEFI firmware does not mean that you need to install Ubuntu in UEFI mode. What is important is below: if the other systems (Windows Vista/7…

Edit4: And this afternoon, I discovered a post on the Ubuntu forums. Please see - [SOLVED] GRUB Menu not showing after Ubuntu Installation

I think that you are going to have to change some settings in your BIOS before you can begin to solve this problem. Again, good luck @Russell_Fry

Edit5: See UEFI Installing - Tips (which is the ubuntuforums UEFI Installing page) and in particular, the section that begins with

"All Acer require supervisor password & enable "trust" on Ubuntu/grub efi files.
