You have been subscribed to a public bug: Many systems including HP, Sony & Toshiba modify UEFI to use Description as part of boot. But they all will boot the fallback or default entry of /EFI/Boot/bootx64.efi. Some systems have that file, some do not even have the /EFI/Boot folder. Boot-Repair already backs up the bootx64.efi. I am having to suggest the rename to many users in forums.
There should at least be a repair option to copy shimx64.efi to /EFI/Boot/bootx64.efi. There may be a few systems that even use that as the Windows default so the copy should not be a default. See this previous bug, but that bug was more on the Windows boot file bootmgfw.efi rename. https://bugs.launchpad.net/boot-repair/+bug/1205947 Also one Brand Acer requires the UEFI Ubuntu/grub shim files to be set as "trust" after creating UEFI supervisory password. I usually see Acer label in Summary Report so suggest that fix, but if Acer seen that should also be suggested. http://paste.ubuntu.com/12125054/ Label: /dev/sda4 BA1A3D0A1A3CC4E3 ntfs Acer VGA: Subsystem: Acer Incorporated [ALI] Device [1025:0940] References: Vendors violated UEFI specs - http://hwe.ubuntu.com/docs/ubuntu-bios-uefi-requirements.pdf [quote]Firmware should not enforce any boot policy other than the mechanism specified in Section 3 of the UEFI 2.3.1 specification [UEFI 2.3.1].
