If you did format your hard drive what was unnecessary but if you did you have to create new partition table, Windows uses NTFS commonly and Ubuntu uses EXT4 nowadays. –  JohnnyEnglish Feb 5 at 10:22

if you want to install Windows and Ubuntu on the same machine firstly you need to install Windows because Windows don't wanna see any other OS's installed on Hard Drive. To find out of the first steps and how to install Windows you can find on its official website and ways of installing Ubuntu including dual-boot over here what partitions do you need for Ubuntu and sharing with other OS's I've already provided in upper comment. –  JohnnyEnglish Feb 5 at 11:06

1- boot from windows 7 or XP CD. 2- select repair --> cmd prompt. 3- input bootRec.exe /fixmbr
