Windows 7: Unable to boot from disc

Hi
I've written a disc so that I can install windows XP and dual boot it with windows 7 which is already installed. I've slipped the drivers for the hard drive (sata) into the installation disc, but when I try to boot from the disc, I get the screen in the attached photo. Is there anyway I can get the CD to boot?
Thanks

Try again using the one-time BIOS Boot Menu key by tapping HP ESC key at boot.

If this fails you likely have a bad burn or slipstream so you may need to do it over. Burn the disk using ImgBurn.

Have you considered virtualizing XP within Windows 7 which is a preferred option now that XP is XPired?

It's not the same PC as in the other thread, it's a custom build. And yes I have considered it but I specifically need XP, with access to all of the resources.

Also, that's how I boot it.

Just a thought but could it be, as the hard drive uses SATA connections, which aren't supported by xp natively, could the reason the disc isn't booting because it also uses a SATA connection which is unsupported. Could that be a cause?

UEFI motherboard. You've got the manual for it?

Maybe, if it was in the box it is probably still there. I can't look for it now though. Why do you ask?

Booting from newer UEFI based motherboards is different than booting from the decades old BIOS based motherboards. I don't have enough experience with UEFI to recommend anything, but I do know they are more restictive in what can be booted. That may be why you're having trouble booting from that disc you burned.

The manual likely refers to how you can turn off the restrictions, allowing more flexible booting options.

TomTom,
You will have less problems by virtualizing your XP using for example Virtual Mode since you have Professional

Boot into BIOS setup to see if there is an EFI Boot Disk in the BIOS Boot order. If so, remove it.

Then wipe the HD with Diskpart Clean Command followed by the command Convert MBR, then Exit. try Install.
