if cannot boot windows cannot configure easybcd settings. idea how can grub2 boot menu appear , not boot straight ubuntu?
need reinstall grub 2 since doesn't appear change grub config boot windows 7 partition , configure mbr easybcd?
i not know easybcd.
have tried grub find windows?
it should find windows , let boot it.code:sudo update-grub
if not want grub update, choose no drives, use spacebar unchoose also. easybcd require install partition?
grub remember reinstall on updates:
sudo dpkg-reconfigure grub-pc
spacebar choose drive, enter accept, not choose partitions
if install partition understand using blocklists less reliable. hardcoded address find boot files. movement of files partition movement, file updates or filechecks may move files , require grub reinstalled boot.
