If windows 7 works fine, It has a virtual PC mode that can be used to run legacy apps, it is basically a VM in the desktop. read about it here:

Virtual PC by itself will require that you have a valid/unused license for XP.

XP Mode (which uses Virtual PC but is actually a pre-configured, fully-licensed, downloadable XP virtual machine) is another great option, which comes included with Professional or better versions of Windows 7.  It is $90 to upgrade from 7 Home Premium to Pro (less than the price of an XP license).

If you really want to install XP, you need to go to HP's support site and get the SATA/AHCI driver for your SATA controller (or go to Intel's site and get the storage/AHCI/F6 driver for your chipset), and use http://nLiteOS.com to integrate the driver into your installation media so you can install XP without getting the BSOD (0x7b is because the storage driver is missing).

Change the SATA emulation mode from AHCI to IDE ...  IT WILL WORK

"Change the SATA emulation mode from AHCI to IDE ...  IT WILL WORK"

First, this is not always an option in today's BIOS'.  
Second, this is a poor workaround only.  Doing this forces Windows to treat your disk as an IDE/ATA drive ... essentially, you give up everything that makes your SATA drive better than the old IDE/ATA drives - setting your technology back some 7-15 years.

Do it right and get the driver for your controller.

I know its a poor workaround sir and it forces you to set your technology back some 7-15 years .... but wait a minute... Isn't windows XP about 9 years old ... ofcourse you dun have to do it for Windows 7. you can't run an older operating system with the technology that wasn't even born at that time.

Fully updated (SP3), you can and you should be running in AHCI/SATA mode ... if possible.  (You also couldn't use a disk larger than 127GB when XP first came out ... that doesn't mean you should only use disks smaller than 127GB with XP now.)  As it is increasingly NOT an option in computer BIOS' to change to a compatibility mode, sometimes the correct way is also the only way.

first ... we both don't really know whether the author of this problem is currently using the XP SP3 ... and there is no guarantee that his driver would work or not... so why not get straight to the solution .... rather than asking him to install SP3 and check whether his driver should work or not.... as he does not have any problem regarding the speed of his HDD, its better to get the system up and running ...

PowerEdgeTechIT ConsultantCommented:
I'm not even saying he needs SP3 for the driver - not that it is difficult to slipstream the required SP, if there is indeed a requirement for the driver, which I doubt - simply that having SP3 will have much of the support we expect from current OS's (not that I still consider XP "current" technology) ... besides, nobody using XP for anything except testing should be at less than SP3 anyway.  As you said, we don't know what SP he has, and since it likely doesn't even matter which he has, there isn't much point in debating the what-if's.  I just don't feel the degraded performance and stability of compatibility mode (no matter how significant or insignificant the effect on his specific system) is an acceptable price to pay for taking the easy way out.

Take care.

Good one... now i think he will seriously consider upgrading to Windows 7 and changing the compatibility mode back to AHCI ....  after our long debate :D ...
 (since what i have read ... even if you slipstream the SP3 ... you will still suffer from this problem of the BSOD since it occurs at the very start of the setup process i.e the SP3 won't effect or change the files of the initial setup... the only way to do it other than converting to IDE mode is to press F6 during startup of install process and install the appropriate driver from the manufacturer)

PowerEdgeTechIT ConsultantCommented:
SP3 added some AHCI drivers, but not many ... so regardless of SP level, you'll need the driver for install, and since his laptop doesn't have a floppy for F6, I recommended he use nLite.

"i think he will seriously consider upgrading to Windows 7"
That would be even better :)

more than likely even if he gets past it not seeing the hard drive there will be other drivers missing that he simply will not be able to get. like nic or video etc.
http://www.microsoft.com/windows/virtual-pc/download.aspx as long as his win7 will validate, that will come up and be a full fledged winxp(no need for a new/seperate winxp key). it is likely the best way to run a stubborn app. we use it for one of our clients, their printer software will not work in win7, but works fine as an xp virtual app.plus you will not need to look at the full xp desktop, you can run just selected apps.
