This question already has an answer here:
Everything went well during installation, I created a 50GB partition for Linux, chose the "Install alongside windows 10" Option, because "something else" did not work for me before. However, after rebooting, it boots directly into Windows 10. I've tried going to the BIOS to change the BOOT order but Ubuntu doesn't even show up there, I tried opening the boot menu (pressing f12 key on my laptop during reboot) and the only option there is windows boot manager, which also boots to win 10.
I tried boot-repair and it said it repaired succesfully but the problem still remains. Here's the report: http://paste.ubuntu.com/p/zkWJMFpJwb/
My computer runs on UEFI and I've already disabled secure boot. I also tried Legacy boot but no luck there either.
Please help, I can't figure out how to get the Grub menu, so I can actually choose which system I want to boot.
