I'm new to linux and trying to dual boot Ubuntu 16.04 alongside with Windows 10 (single-HDD Toshiba, Win 8 was pre-installed)
There were no issues during install but I'm not able to load into Ubuntu (or see any bootmanager menu at all). After trying several suggestions, I'm now able to boot Ubuntu via grub only if I hibernated from Windows or if the laptop wakes up from a complete discharge.
Booting after shut down/restart from either OS directly boots Windows without any boot manager.
The BIOS/UEFI settings only list an option to alter device boot order; no option to choose boot manager or which partition within the (only) HDD.
Things I've tried:
--Disabled fast-boot & secure-boot
--Reinstalled Ubuntu after wiping its partition
boot-repair (pastebin here)
bcdedit /enum lists only Windows 10. Setting the path to
\EFI\ubuntu\shimx64.efi (as suggested by boot-repair) did not change anything.
grub-install from a live-USB, which gave an error related to blocklists (see comment thread here)
