Need to dual boot Windows 7 and XP, with Windows 7 installed first.

Hello,  I recently installed Win 7 64 bit on a new HDD.  I still have a lot of software (games) that doesnt work right on Win 7 so I'd like to put XP Pro 32 bit on the same disk, either as a dual boot, or by using a virtual machine.  I made a separate partition for XP already but I can undo that if it recommended that using a vm would be better.  
Thank you!

What version of 7 are you considering? If it is Enterprise/Professional/Ultimate, the n XP Mode might be a good solution for you as a fallback plan.... It seamlessly integrates Windows Virtual PC, with a licensed copy of XP, into your Win7 enviroment......

Meaning you can install an app on the Virtualized XP, and have a shortcut to it on your Win7 menu, and it runs under the XP environment, but while you are logged into Win7....

Hi Johnb6767, Win 7 Ultimate is already installed on the HDD.

Ive tried to get these programs that I want, to work on 7 but theres dependencies, as well.  Such as punkbuster A and B.  It appears that it would be waaaay easier to dual boot than to mess with all the little glitches with these programs.

EasyBCD http://neosmart.net/dl.php?id=1 should do the trick - install XP on the spare partition, repair the Win7 boot loader with the Win7 DVD and set up the XP as a boot option with EasyBCD.

Hi yarwell.  Ok.  So can you explain the steps?  I presume I need to boot to the xp cd, install it.  Then what do I do?  How are where/when do I use the EasyBCD?  Do I need to put the EasyBCD on a cd first?  - Thanks!
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
And, are we certain that a dual boot is better than installing a virtual machine?
PrecifijoCommented:
You install windows xp... once you install xp yo won't be able to start windows 7. Log into windows xp and use the EasyBCD program to created a booter that will recognize windows xp and windows 7... simple as that  ... it seems pretty straight forward :-)
PrecifijoCommented:
Virtual machine won't perform as good as a native installation.... But if you are only installing it to se this program then it makes no sense to dual boot. It's too much of a hassle having to turn off the computer just to use a single program and then reboot again to keep using your everyday OS.... IMO.
yarwellCommented:
either do what Precifijo says, or install XP  which will break Windows 7 boot installation. Then use Windows 7 DVD to repair windows 7 boot. With Win7 running download and install EasyBCD and add the XP option to the boot menu for the Win7 boot loader.

mmk let me try this.  brb
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Ok so I booted to the xp cd and let the setup complete.  Then the install said "Setup will complete after rebooting".  But it reboots to the beginning of the install.  It's in some type of loop here.  I cant get the install to continue.
PrecifijoCommented:
Did you forget to take the CD out?

There are no more hardware dependencies with XP Mode. Shouldnt be an issue for you.....

Plus the apps you install in XP Mode can be directly accessed from the Windows 7 start menu, without having to boot another OS, much more convenient.....

I took the xp cd out and restarted and it says "no boot device found, press cntl + alt + delete to restart."  
Ummm, ok now I cant decide what I should do - download xp mode, or put a full xp on the partition.
Is the xp mode a "virtual" pc thing?  What are the negatives and positives of that?
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Ok I fixed the win7 mbr and deleted the partition I had created.  Now I am trying to download xp mode, and after I choose the edition (Ultimate 64) I am unable to continue b/c the "choose a language" field is grayed out.  I am using Ultimate 64 N.  I wonder if Im not able to get xp mode for that?
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Ok now the "choose a language" field is open.  I am in the process of configuring this "xp mode".
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Now what I need to know is, will my games that dont work well in my win7 look/work good in the virtual pc?
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
So my current questions are these:
1.  Why didnt the xp install to the other partition continue after I took out the xp cd and changed the boot order to hdd first and cd second?
2.  What are the pros and cons of running games in the xp "mode"?
3.  Does anyone know how the games will run in the xp window?
PrecifijoCommented:
I don't run games in xp mode but I can tell you that depending on how much resources they use, they won't perform as good as in a native installation. Specially games with high graphics quality. Also you have to take into account the fact that you're using more RAM when you're running a virtual machine and therefore you have less available RAM for the games. I'm not sure why the installation didn't finish. Something must have gone wrong... maybe your didn't mark the partition as active or something.. I think I've read somewhere that in order to dual boot two versions of windows the older version must be installed first and the latest version last.

Thats the MS "supported" method to do it. And the games, your probably right on as well.

You cant just change the boot order , you have to make sure that boot order is right in Windows as well. I have never done a dualboot with 7 first, but I can guess that the Win7 disk is the active partition, and you might need to run bcdedit, to even list the XP install as a boot option... Windows 7 doesnt use the old boot.ini file....
