I want to install Linux/Ubuntu on this desktop but cannot boot from the USB to do so. I am not concerned about dual boot or partitions.

  • The Acer Aspire TC-895-UA92 Desktop is not booting from the USB. The USB has been made into a bootable USB using rufus on windows by burning the 18.04 ubuntu iso image onto it.
  • Starting the desktop again after shutting down, the bottom of the screen on start up says to push F12 for the boot menu and Del (delete key) for the BIOS. The key F12 is pressed but no change in the boot start up of Windows occurs. No other key works for the boot menu, and only Del works to bring up the BIOS screen.
  • From the BIOS there appears to be no option to enable F12 option as mentioned in SU answer or as displayed in this YT video for another Acer computer. I have looked repetitively for it and failed to find any reference to F12 but there is an option for Boot Menu which should activate via F12 but does not function in my case.
  • At the BIOS, the Boot Options tab, I changed the order of the Boot Device to be the Removable Device to be the 1st Boot Device, and have the HDD Windows Boot Manager to become the 3rd Boot Device.

After restarting multiple times, and using all options of F12-F1 and Esc only Del works bringing it back to BIOS setup or the Windows start.

The desktop comes with a keyboard in the box of which the Function keys are not working without pressing them with the Fn key or Alt. So you cannot just press F12.

You can use a different keyboard where this is not a default and then use F12 which will bring up the boot menu allowing you to choose the device to boot from when the order of the OS is after the USB or you can press the Fn key with the function keys.

In addition to Vass note about actually "pressing F12" when it needs a meta key pressed, please note you may need to disable secure boot.

It has to be formatted as GPT and not MBR in order for an Acer 895 to recognize it.
