I have Ubuntu already installed. I wanted to get windows 7 as well, I followed the instructions I was given, to partition my hard drive and to format it to a NTFS for Windows but now When I try to boot from HDD I only get Windows. I am seeing that I was (if done right) to get a GRUB menu at start you, so I may pick which one I would to start up.
I would much thankful of your help, also I have no issue with having to flash my hard drive and start from scratch.
