I recently migrated from a wubi install to a full install on my windows 8 machine. i referred to this article https://help.ubuntu.com/community/MigrateWubi and adopted the automatic migration. Everything went well until i booted. on booting i couldn't see the option to boot into windows in the grub menu. so how do i fix this so i can boot into windows too. Any help really appreciated.

Thanks in advance!
