If you have Windows Vista installed and have installed Windows 7 in another partition using a clean install, the Windows 7 bootloader will automatically add an entry for Windows Vista. By any chance, if you have managed to screw this up and want to add the Windows Vista boot option to Windows 7′s bootloader, just follow these steps.
Assuming that you installed Windows 7 on C: and Windows Vista was installed on D:
To Add Windows Vista Boot Option to Windows 7 Boot Menu
Open Command Prompt as an administrator or an elevated prompt and type
C:>bcdedit
This will list the current boot manager configuration. Note down the identifier key which is in the format
{e96c8447-8171-11de-9007-b10454ebd432} or something like it.
C:>bcdedit /copy {current} /d “Windows Vista”
This will copy the current bootloader into a new entry for Windows Vista. However selecting it will still boot into Windows 7.
C:>bcdedit /set {e96c8447-8171-11de-9007-b10454ebd432} device partition=D:
C:>bcdedit /set {e96c8447-8171-11de-9007-b10454ebd432} osdevice partition=D:
These two commands will set the new boot entry to point to your Vista partition and load from it.
You can reboot and see the changes. You can also Run > MSCONFIG and check out the entries in the Boot tab.

As Manan pointed out, You can also use EasyBCD to edit and manage your bootloader entries using a GUI.

My two hard drive, a 160G (the three areas, C, D, E), a 1T (a district, F 930 + G, partition approach is extended.) Because I can use only one system, so the installationWindows 7, When he deleted the C drive and then rebuild; results of reconstruction, it more than a 100MB disk. Do not know what to use, and did not feel too comfortable. More a 100MB disk. To exit the installation.
PQ prompted board disk error, come on, whether it, cancel, found that even a second hard disk is also wrong? Windows 7 to do what? I installed Windows 7 did not come across when hitting the second hard drive, because I have been a lot of important information in the 1T’s hard drive.
Depressed the problem came. Board PQ, found two hard drives are all yellow error. Well no matter. Exit PQ.
Mounted Windows PE (XP), found that disc still think that an alternative, not to install Windows 7, boarded the PQ, prompted an error, point of repair.
Depressed, point of this fix, the problem out big (funeral), restored, enter the PQ, two hard drives is still yellow.
Well, dare not touch, boarded the Ghost restore XP, This is just great the first zone plate are all gone. However, to a second hard drive to check the logic area (1T).
That is not not restored?
And then into the XP CD, new clothes look at the steps in the XP installation partition, found that all disks are in, delete the Windows 7 built on the two disks. Reconstruction back to the system area.
And then finally can use Ghost to restore a Windows xp.
The strange thing is that Ghost is still not detected D, E area, but access to XP, all the partitions still exist.
Currently the data is backup, D, E zone data. Depressed, the next really big play. . There F disk is 930G, I have been using the 900G, the 900G do not know how to back up.
Lessons ah, we, when you install Windows 7, if the original hard disk with data, do not build disk partition with Windows 7, Windows 7 build after-hours used, PQ will prompt an error. NND, the connection did not move off the second disc is also wrong. Although the data also, but he’s very dangerous, do not know how to run.
