I tried installing 15.04 to a brand new Acer Aspire E15 laptop (that came with Windows 8 or 8.1) from a live USB. The installation went off without any warnings, but it won't boot to the HDD (live USB still works fine).
I tried searching for related problems, but just about every one was about trying to dual-boot Windows/Ubuntu - I did a full, clean install of Ubuntu (using the installer option to wipe the existing HDD partitions). The remainder suggested using boot-repair, so I tried that. That, too, worked without a warning, but it still won't boot from the HDD. The output is here: http://paste.ubuntu.com/12015975/
(A couple threads also suggested manually enabling the boot flag on the boot partition, but when I checked with gparted, it was already set.)
During boot, there are a few errors flashed briefly before the "default boot device missing or boot failed" error. They flick by quickly, but they look like they say there's a missing "/EFI/Microsoft/Boot/grubx64.efi", and then another one with a similar name but that seems to have the word "manager" in it.
This is my first time installing Ubuntu on a device with UEFI, so it's entirely possible I just missed some common and obvious step that disables some security thing. For example, in the BIOS there are options to "erase all secure boot settings", "select an UEFI file as trusted", and "restore secure boot to factory default" - I didn't touch any of those. One thread led me to a video about "unlocking hidden pages" in the InsydeH20 BIOS manager, but that only seems necessary to enable virtualization.
