Dual Boot two different XP's?

Hi, okay basically I've gone thru the whole dual boot process before however not in this situation and I'm curious how to go about it. I already have XP installed on my current system however I have another copy I'd like to install as well, it's a real slim version that quickly loads and I want to run a few tests. I also however don't wish to screw up my current XP install. How should I go about dual booting two copies of XP? I was thinking make another partition and set it up on there but both copies would look to C for certain boot info so I'm not sure if that would even work..

ideas?

It's not too complex so long as you have pre-vista OSes. Install windows XP to the secondary partition, and then add an entry into the boot.ini of windows in the primary partition, that points to the new installation. E.g.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows XP Slip Boot" /noexecute=optin /fastdetect

When you boot, the official boot loader will be on C:, but when you select the second boot item, it will boot the second windows up. When the second windows boots, it will should use it's own hard drive as C:.

As always, make backups of boot.ini and have a recovery disk handy just in case. Modifying boot.ini in a bad was without a backup is one way to mess up your system, so keep a backup good copy handy. I usually just copy boot.ini to boot.ini.bak.

It's FAR better if you want a multi-boot system to use a 3rd party boot manager that allows better control of the partitions;  lets you isolate all of the OS's from each other; etc.   I use Boot-It NG for this (and most of my other) systems ... it's exceptionally reliable;  allows configurations you couldn't begin to achieve without it; and is a rock-solid little utility.   It's also an excellent partition manager & image/restore tool.   http://www.terabyteunlimited.com/index.htm

Note that every OS is completely isolated ... all of them "think" they're on the first partition (and thus install to C:) ... it's trivial to image the individual OS's and restore them at will (takes less than 10 min) ... etc.   All of my systems these days are multi-boot; and I wouldn't dream of using anything besides Boot-It to manage them.

On this system, I can boot XP Home, XP Pro, XP Pro x64, XP MCE, Vista Ultimate, Vista Ultimate x64, Ubuntu, Mandriva, and Windows 2000 :-)   The menu is currently a bit different than it was when I last took a snapshot ... but here's the menu from a couple months ago (before I added Win 2K and XP x64):   [At the time I had an additional copy of XP installed that I was doing some testing with ... similar to what you want to do]

Why you don't install VMWare since they are both XP?

Microsoft's competitor to VMWare is Microsoft Virtual PC... and it actually works pretty darn good. In any case, though, OP wants to have two different bootable partitions, not a virtual pc.

I second BootIT NG as a boot manager, if you are looking to do this the proper way. Terabyte Unlimited makes good products. Beats the pants off of Partition Magic's bootloader "Boot Magic".
