I installed Ubuntu 17 but it would not boot up after install was complete. I think it is a problem with the MBR. I tried installing it again and I get the error
grub2 install failed: installing for i386-pc platform grub2 -install :warning this GPT partition label contains no BIOS boot partition……..
Here is what i get via fdisk

Answer
you need to install grub in efi mode try :
sudo apt-get install grub-efi
install-grub –target=x86_64-efi
if you get the error “Can not find EFI directory”, then you have installed in bios mode.
It can be converted, but to avoid future problem maybe just reinstall.
