Please, help my with a problem. I try to install Ubuntu 15.04 (or 14.10, it's not important) dual boot windows 10. My notebook is Lenovo z570 with BIOS not UEFI and installed windows 10 x64. When i installed windows 10, she parted disk to GPT, which led to problems with installing Ubuntu. After Ubuntu install, and reboot, GRUB2 not run, instead this windows boot manager start.
The following description of the disk
Disklabel type: gpt
Disk identifier: D1CB061A-38BF-48CE-BD0D-67E9E1DC0AB2
Device Start End Sectors Size Type
/dev/sda1 2048 923647 921600 450M Windows recovery environment

/dev/sda7 945326080 976773134 31447055 15G Linux filesystem
I created BIOS Boot Partition, and tried to reinstall grub (grub-install by chroot to /dev/sda ) but this not work.
Maybe i'm doing something wrong...
Is there a way to intall Ubuntu dual boot Windows 10 at GPT/BIOS ?
