This shows a few interesting things: - The disk path for both Boot0000 (the Windows boot entry) and Boot0004 (the Ubuntu boot entry) match, which indicates that the Ubuntu boot entry is correctly set up to use the same ESP that Windows was using. Please confirm that /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi and /boot/efi/EFI/ubuntu/shimx64.efi are both present on your system. - The currently-booted option, Boot0001, is also pointing at the Ubuntu bootloader on the hard disk. Can you describe exactly how you booted this system to Ubuntu? - All of the boot entries in your list show "junk" characters, "RC", at the end of the device definition - *except* for Boot0004, which is the (non-functional) boot option created by the Ubuntu installer using efibootmgr. I don't have a straightforward way to include this 'RC' for testing, and I don't know what this is supposed to mean. But since you have two other ubuntu entries that do have the 'RC' appended already, we could try making one of those the default and see what happens. Could you try running: sudo efibootmgr --bootorder 0001,0004,2002,0000,2001 and rebooting, and see if this takes you to the grub menu on boot? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1437797 Title: I can't boot ubuntu after installing it dual-boot from kubuntu 14.10 CD prallel to windows 8.1, UEFI secure boot, on an Acer Aspire E15.
