I had Windows 10 on my Acer aspire ES14 (1T hdd, 4Gig RAM, Intel celeron N3350), but due to the latest update, it created a conflict where the update would happen, but not complete, and that would create a 100% disk usage problem.
After repeated re-installs, it led to re-installation problems with Windows recovery.
So I decided to rather install Ubuntu. I was a novice wrt Ubuntu and clueless. I have since learnt a little bit.
I installed Ubuntu 19.10 as a single boot, thus wiping the hard drive completely. All went well with the installation, and when asked to restart and remove the installation media (live usb drive), i found the message appearing, no bootable device.
I have tried using UEFI to address the issue: 1. I disabled SECURE BOOT and even re-installed ubuntu (a clean install, wiping the hard drive again), but this still shows no bootable device. 2. I attempted to switch to LEGACY, but do not have the feature that allows such a switch. Basically i'm stuck in UEFI.
I ran a boot info, and as follows, is the report: http://paste.ubuntu.com/p/pt7j7wzYsH/
Basically I can only use Ubuntu, by leaving the live USB in, which gives limited functionality.
Please can anyone help me to ensure Ubuntu loads directly from the HDD? Please include step by step instructions as Im still very new to this, and even copying boot loader files to the ESP leaves me bewildered...
