I tried to install Ubuntu 18.04 on Acer TravelMate P278-MG, but it bootloops 1. It starts up, shows Acer logo 2. It says:
System BootOrder not found. Initializing defaults.
Creating boot entry "BootXXXX" with label "ubuntu" for the file "\EFI\ubuntu\shimx.efi"
Reset System
Where XXXX - number, depending on the BIOS configuration(I tried Legacy, UEFI with SecureBoot on and off, different boot devices(there is Linplus lite boot device, which is strange)) 3. goto 1.
I found the solution on another forum. Two steps. Select a UEFI file as trusted and given it a custom name. Then go to the boot menu and select it as first priority as described below.
I want to add something to Melebius' answer for users with HP UEFI/BIOS:
In those cases, there is no option to choose a trusted UEFI file, however, there exists the option for a Customized Boot under the Boot Options menu. You have to add custom boot path and enter
EFI\ubuntu\shimx64.efi
. Then you have to change the boot priority and put Customized Boot on top of the list for UEFI Boot Order.Addition to the answer of @Xeno you have to GO to "BOOT ORDER" and MOVE the "Custom Boot" at the top of "OS Boot" it should be like:
It may be a lifesaver so I've felt the need to add this answer.
