I had windows 8 , I dual booted windows with ubuntu 14.04 after a while. Now ubuntu is in partition 1 sda1
and you type this command in Terminal
sudo fdisk -l
WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

Partition 1 does not start on physical sector boundary.
It is clear that partition is not at 63 sector and not multiple of 8. After installing ubuntu, when I boot my system it directly boot up into ubuntu and GNU Grub 2.02 shows only Ubuntu Advanced options for ubuntu system setup
There is no windows boot manager displayed. I am completely beginner . Please help me out and explain clearly
I am also adding the result of sudo parted /dev/sda print

being useless with GPT disks. Trysudo parted /dev/sda print
orsudo gdisk -l /dev/sda
instead. Edit your question to add one or both of those results. – Rod Smith Aug 06 '15 at 23:15
