Dual Boot Installation with Windows 7 and Vista

How to Setup a Dual Boot Installation with Windows 7 and Vista

information   Information
This will show you how to install Windows 7 and Vista to dual boot with when you already have either Windows 7 or Vista installed first.
Note   Note
With a dual boot installaton, you will have two operating systems (OS) installed. When you start the computer, you will have the choice to choose which OS you would like to start up to. This method is the easiest way of doing a dual boot with these two operating systems.
Tip   Tip
When dual booting with another OS (ex: Vista or XP), you may not always have that OS partition show up in Computer with a driver letter in Windows 7. If this happens, then you will just need to add a drive letter to the OS (ex: Vista or XP) partition in Windows 7 Disk Management for it to show up in Computer with a driver letter.

Here's How:
1. If Installing Second OS on a Separate Hard Drive
NOTE: This is if you are going to install the second OS (Windows 7 or Vista) on a separate hard drive than the first OS in installed on.
A) Go to step 3.
2. If Installing Second OS on another Partition on the Same Hard Drive
NOTE: This is if you are going to install the second OS (Windows 7 or Vista) on a different partition on the same hard drive than the first OS is installed on.
A) If Vista was installed first, then create a new partition for Windows 7 (second OS) to be installed on later if you do not already have one to use. (See screenshot below)

B) If Windows 7 was installed first, then create a new partition for Vista (second OS) to be installed on later if you do not already have one to use. (See screenshot below)

3. Insert the second OS (Windows 7 or Vista) installation DVD, and restart the computer to start installing it.
A) If Vista was installed first, then select the new partition (step 2A) or drive and do a clean install of Windows 7 (second OS) on it. (See screenshot below)

B) If Windows 7 was installed first, then select the new partition (step 2B) or drive and do a clean install of Vista (second OS) on it. (See screenshot below)

4. When the second OS is finished installing you will now have the option to select which OS to start to in the Windows Boot Manager screen at start up. (See example screenshot at the top of the tutorial)
NOTE: Whatever OS you install last will be the OS listed first in the Windows Boot Manager screen at startup.

5. This is what you will see in Disk Management below if you installed the second OS on another partition on the same hard drive (step 2).
A) If Vista was installed first. (See screenshot below)

B) If Windows 7 was installed first. (See screenshot below)
