Windows 7: Dual Boot Installation with Windows 7 and XP

Well done.
It does work better with the right drivers.

Haha, yeah, it does. Only problem is the WLAN card (Broadcom 802.11n Network Adapter) doesn't work at all. It's just not being recognized. This seems to be a problem with most laptops after a clean install, but eh. At least I have a Wireless USB card lying around.

Broadcom 802.11n Network Adapter, have look here:

Hello,
I own a HP Pavilion dv8-4180us Entertainment Notebook. I recently discovered that several programs from my desktop computer, which is currently running XP, were not compatible with windows 7. I followed this tutorial in an attempt to create a duel boot system using method 2. I have no RAID on my laptop but I did have to slipstream my SATA Drivers onto a new install disk. I am attempting to install the duel boot onto a removable hard drive. I have tried to install several of my operating systems such as: Windows XP 32 bit Home Edition SP3, Windows XP 32 bit Professional SP3, and Windows XP 32 bit Home Edition (No Service Pack). Every single time I boot from disk my computer begins to load the setup, but at the end of the step before it asks you to accept the agreement, it crashes. Now, the SATA drivers I downloaded were from Intel's website. I used textmode and I slip streamed all of them, hoping the computer would grab what it needs. I do not know if this is the problem because it never actually says "No Drivers Found", or "Could Not Locate Hard Drive". When it crashes it goes to a blue screen of death and says, (Paraphrased) "The computer has ended operations due to a detected threat. If this is the first time you have received this message, please restart your computer, if not their may be viruses or new hardware installed that is causing a problem...". I thought it might be my external hard drive so I to install without it. No change in the result. I have read many forums looking for a result and I looked at many of the previous posts here without any luck. I really want to see this work and have been trying everything from loading different drivers to (very carefully) removing RAM sticks from the motherboard. I appreciate any responses or new ideas and appreciate you reading this long drawn out post.

You cannot install WIndows to an external HD connected by USB.

I thought it said you could:
1. To Create a New Partition from the Windows 7 Hard Disk Drive
NOTE: If you want to install XP on a separate hard drive instead, then skip this step and go to step 2.

Nevertheless, that still doesn't explain why when I unplug the hard drive it still crashes.

Hello Jgalt,

You can only install a OS on a internal HDD, and not on a external HDD unless the external HDD was connected with a eSATA connection without any adapters used in the connection.

Okay Thanks. I partitioned my HD but it still gets the same error. Nothing but the power cord is plugged in.

If this is the error you quoted earlier about possibly threats, install, update and run a full Malwarebytes scan.

Next I would try another internal HD with the Windows 7 HD unplugged. If that fails, reset the CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS

Check in BIOS setup if Windows 7 is installed in AHCI mode. If so you'll need to try to find AHCI SATA drivers for your computer.

We will continue to help you troubleshoot to resolution however you might also try installing your XP Programs in Windows 7 Compatibility Mode or try running XP virtually from within Windows 7 using freeware like Virtual Box, VMWare or Virtual Player.

Are you using both setup inf, & Multiple drivers. Also add all Sata Controllers.
