Dual Boot Installation with Windows 7 and XP

How to Setup a Dual Boot Installation with Windows 7 and XP​


   Information
This will show you how to install Windows 7 and XP to dual boot with when you already have either Windows 7 or XP installed first.
   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
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.
   Warning
To stop XP from deleting your Windows 7 System Restore Points everytime XP is started, then see System Restore Points - Stop XP Dual Boot Delete to hide Windows 7 from XP.

OPTION ONE

When XP is Installed First


NOTE: If you have a RAID setup, you will need to have the Windows 7 RAID drivers on a USB flash drive available to select and load while installing Windows 7.
1. Do step 2 or 3 below for where you wanted to install Windows 7 at.

2. To Create a New Partition from the XP Hard Disk Drive
A) With your Windows 7 installation disc boot into the Command Prompt from the System Recovery Options screen.
NOTE: Make sure that the CD/DVD drive is selected first in the boot order in the BIOS.

B) In the command prompt, select and shrink the XP volume by how many MB (1024 MB = 1 GB) you want to have for this Windows 7 partition. (See screenshot below)
NOTE: You would do steps 2 to 9 in METHOD TWO at that link. Windows 7 will need a minimum of 16 GB (16384 MB).
XP-W7_1.jpg
C) Click on the X at the top right corner to close the command prompt. (See screenshot above)

D) Click on the X at the top right corner to close System Recovery Options. (See screenshot below)
XP-W7_2.jpg
E) Go to step 4.
3. To Use a Separate Hard Disk Drive than the XP Drive
A) Boot from your Windows 7 installation disc.
NOTE: Make sure that the CD/DVD drive is selected first in the boot order in the BIOS.
4. Click on the Install now button. (See screenshot below)
XP-W7_3.jpg
5. When you get to this point, select the partition (step 2) or hard drive to install Windows 7 on. (See screenshot below)
XP-W7_4.jpg
6. Finish installing Windows 7.
NOTE: You would start at step 9 in that link to finish installing Windows 7.

7. When finished, restart the computer to have the option to boot from XP (Earlier Verision of Windows) or Windows 7. (See screenshot below)

   Note
If you are only booting into Windows 7 and do not have XP listed in the Windows Boot Manager, then you can install only EasyBCD (step 8 Option Two below) to add XP (or Windows 7) while started in Windows 7 the same way to the boot list.

Example.jpg



OPTION TWO

When Windows 7 is Installed First





   Warning

1. To Create a New Partition from the Windows 7 Hard Disk Drive

    • bootrec /FixMbr
    • bootrec /FixBoot
    • bootrec /RebuildBcd
  • Exit the command prompt and restart the computer.
  • At this point, Windows 7 should boot up the same way before trying to install XP.
  • Continue to step 8 below and run EasyBCD from Windows 7 instead.

7. In XP, download and install .Net Framework 2.0 (32-bit) version or .Net Framework 2.0 (64-bit) version first, and EasyBCD (free version) for your 32-bit (x86) or 64-bit (x86) XP.
NOTE: In XP, Net Framework is required to be installed to run EasyBCD. After you click on Register (at bottom of link) for the free EasyBCD, registration is not required to download it.

That's it,
Shawn

I assume you mean you installed XP on another partition?

Please post a screenshot of Disk Management window.

Hi guys,some help needed please.

I bought a new hard drive so I can duel boot my pc, xp and win 7. I also bought 4gig of ram to replace the 2gig I had in there. So before doing anything else I took out the old ram and put in the two sticks of new (in duel ram mode.) Booted the pc up and the post screen shows 4gig of ram in duel mode. Xp only shows 3.50 because it's only 32 bit as expected. I've now put in the new hard drive, formatted it and installed 32 bit win 7, but that only shows 3.50 of ram as well. :confused: So am I wrong in thinking that both 32 and 64 bit win 7 should show the full 4gig like Vista.

If win 7 32 bit is not able to show 4gig is it to late to uninstall it and put 64 bit on.

Hello Ash,

Yes, you can format the 32-bit Windows 7 and install the 64-bit Windows 7 if you like, and if your computer has a 64-bit CPU and 64-bit driver versions for all of your devices.

Afterwards, you may need to remove the old 32-bit Windows 7 from the Boot Manager list as at startup though from within the new 64-bit Windows 7 installation.

Hi Brink, thanks for the quick reply.

Just checked with a friend who's done the same as me and he says his 32 bit win 7 is showing the full 4gig. Can you think of any reason why mine isn't.

Could be because of the RAm he has in his laptop/desktop...

Some RAM report less because of the quality of RAM or some settings in the BIOS that is limiting it

Hi Brink, yes it was a clean install on a new drive.

Hi Zidane24, yes you could be right. but I wouldn't know were to start looking or what I was doing to be honest. I'm just afraid that if I take off 32 bit win 7 and put 64 bit win 7 on, the ram might still only show 3.50 gig.

As for the quality of the ram, it's Corsair XMS2 and it's in a desk top pc.

Thanks anyway guys. I'll give the store were I bought if from a call tomorrow.

Do you by chance have a integrated graphics chip?

If you do, then the missing 512MB may be allocated to it in the BIOS thus only giving you 3.5 GB available.

It may sound silly but what have you got to lose by installing the 64-bit W 7 to see what it'll report, if you don't like the outcome put the 32-bit back on. ;)

I have a problem booting to XP on another drive now that I installed Windows 7.

I have XP installed on one hard drive and I had Vista on another drive and upgraded to Win 7 on that drive. I used to be able to go to my bios under Boot Device Priority and change what drive I wanted to boot too and I could use XP. Now that I have Win 7 installed the XP drive is not showing up in Boot Device Priority. In my bios under Hard Disk Drives I see my XP and my Win 7 drives but when I go to Boot Device Priority I see only my Win 7 drive and one of my dvd drives. I can't find anything to change in my bios that will help show my XP drive anymore. Any advice? Would EasyBCD work for me?

Did you mean in the OS list in the Windows Boot Manager at startup instead of the boot priority list in BIOS?

Hi Brink,

It is in the bios. I get there when the computer starts and I push F2 and it goes into the bios. Then I could decide what drive I wanted to boot using Boot Device Priority. I don't know what the Windows Boot Manager is or how to get to it.

Mindcrime,

The "Windows Boot Manager" is the list of OS's that you can select from at startup for what OS you want to be started. You can see a sceenshot of it in the Example at the top of this tutorial below. See it and the related links for more about this.

http://www.sevenforums.com/tutorials/2282-default-operating-system-change-default-boot-os.html

You can do step 7 on in METHOD TWO in the tutorial on the first page here to use EasyBCD to make sure XP is added to the "Windows Boot Manager" so that you can select from either XP or Windows 7 at startup.

Hello Dnguyen, and welcome to Seven Forums.

Since you E: drive with XP is listed as the boot drive, use EasyBCD to remove the Windows 7 entry, then readd Windows 7 using the D: drive in step 10 of METHOD TWO in the tutorial instead of E: .

Hope this helps,
Shawn

Hi guys, I've fixed the problem I had with only 3.50 of the 4GB of ram showing in win 7.
A bios flash fixed it. :doh:

The only other issue I have is it doesn't matter if I'm in xp or 7, my xp drive stays as the c drive. Not that it's much of a problem.

Thanks again to all that replied to my post. :thumbsup:

Hello Gohorns, and welcome to Seven Forums.

Microsoft is correct, but that is the purpose of METHOD TWO in the tutorial to repair it afterwards if you already had Windows 7 installed first.
