Windows 7 Lost After Installing Windows XP

Some month ago my friend tried to install Windows XP as Dual boot operating system while windows seven is already installed into the computer. After finishing all installation process he restarted his computer, he gets shocked ! because he lost Windows 7, and Windows XP started directly without asking for OS selection...

He asked me about that but I didn't know about this at that time...
after some month the same problem occurred with me...incidentally I have found the solution to this problem which is occurred because of the reformation of the boot manager.

Step-1: Insert Windows 7 installation disc...

Step-2: Restart your computer, wait... when " INSTALL NOW " message gets displayed, don't select it, instead of this select Repair Option.

Step-3: Select Boot Repair related option and follow procedure... Restart, your problem should be solved.

  2. 1. Boot from your Windows 7 DVD.

  4. The windows 7 repair will fix the Windows 7 boot issue but you may have to use bcdedit to manually add back in the {ntldr} entry that makes windows xp/nt function.

    here is an excerpt from:

    you would do this in Windows 7 after running through the steps outlined by sabertooth.

    1.Open an elevated command prompt.
    2.Type the following to create a boot loader for Windows XP.
    bcdedit /create {ntldr} /d "Windows XP"
    3.Type the following to set the device to where Windows XP is installed. I used D: in this example. Replace it with the drive letter of your XP installation.
    bcdedit /set {ntldr} device partition=D:
    4.Type the following to set the path.
    bcdedit /set {ntldr} path \ntldr
    5.Type the following to add this boot loader to the boot up screen.
    bcdedit /displayorder {ntldr} /addlast
    6.Reboot the computer.
