gpt detected. please create bios-boot partition (>1mb, unformatted filesystem, bios_grub flag). can performed via tools such gparted. try again.i attaching screenshot of gparted, view of disk system :
alternatively, can retry after activating [separate /boot/efi partition:] option.
-dev-sda - gparted_001.png
sda1 = windows 7 c:/
sda4,5,6 = windows 7 partitions (all data)
sda7,8 = ubuntu installation , swap area
how proceed solve problem, can continue use windows 7 , ubuntu in dual-booted harmony ? if have make new bios-boot partition, how go it? if not required, easy fix?
no expert here, have tried running update-grub in terminal see if picks windows partitions , adds them boot menu?
open terminal , run following:
again, post output here if doesn't work.code:sudo update-grub
