Laptop was previously a Win10 system, Intel Core i5, 8GB RAM, 1TB HDD.

Created a bootable USB key to install Ubuntu 18.04 (no dual boot) and after going through the whole process my expectation was that a simple reboot of the hardware would boot into Ubuntu. I have done this before with different hardware using Ubuntu 16.04.

Result of reboot was a message from the system telling that no boot device could be found.

What am I missing?

  • Did you say yes when asked to install Grub? – Katu Oct 16 '18 at 14:59
  • Acer has an unique requirement of setting "trust" from within UEFI. Similar details: http://askubuntu.com/questions/627416/acer-aspire-e15-will-not-dual-boot & https://ubuntuforums.org/showthread.php?t=2297947 & https://ubuntuforums.org/showthread.php?t=2358003 – oldfred Oct 16 '18 at 15:39

Did you disable secure boot? F2/F12/Del on startup

When following the install process, did you ensure to install grub to the MBR of your boot device (or rather the correct boot device)?

Usually it will be something like /dev/sda or /dev/nvme0n1.

There's a screenshot here that should help to show what I mean (although for an older Ubuntu installer).
