ubuntu windows10 in GPT HDD GRUB Boot

some thing wrong with my input, I can just use English  -_-!!!

The HDD have two kinds of formart, GPT and MBR ,win10 and new version are GPT by default which CAN NOT use EasyBCD!!!   but we can use ubuntu boot menu(GRUB style).

we can use USB Ubuntu System and start with UEFI Mode(we can select it in BIOS),then we can  run the script below to install auto boot repair soft:

sudo add-apt-repository ppa:yannubuntu/boot-repair
sudo apt-get update
sudo apt-get install boot-repair boot-sav

(must with internet)

then we can run Boot Repair, it will reinstall ubuntu GRUB menu into HDD

then we can also run GParted tool to resize or reconfig our HDD partion.

Boot Repair Result:

and it will generate a boot detail log.
