I cannot boot Ubuntu installed alongside with Windows 8.1 on my laptop with UEFI (Sony SVP1322R4RBI).
I followed the instructions on dual boot Windows 8 and Ubuntu, tried Boot-Repair with «recommended repair», then I manually set {bootmgr} option using Windows bcdedit, both
bcdedit /set {bootmgr} path EFIubuntugrubx64.efi
and
bcdedit /set {bootmgr} path EFIubuntushimx64.efi
But there is no any effect, the laptop boots directly into Windows.
Here is the report of Boot-Repair http://paste.ubuntu.com/9616775/
Maybe some advanced options would be helpful...
UPDATE 01
Here is my UEFI BIOS screens: link to dropbox (I cannot post images)
I've tried all F-keys, but I can't load boot menu.
Solved
I've renamed grubx64.efi
into EFIBootootx64.efi
, now everything is ok! As I understand, some models of Sony VAIO use only bootx64.efi
bootloader.
