Error Installing Windows Xp Pro with BootCamp

I was in the middle of installing when it asked me for my key code. I had forgotten, so i powered it down. After i found it i turned the power back on. Screen came up saying to press any key to boot from disk, which doesnt let me boot. Then it turned on to Windows automaticly, said setup restarting, and then gave me a lsasse.exe error, saying there was an invalid paramiter was passed to a service or function. Anyone know the issue?

Have you try reinstalling it?

As a Mac doesn't use a BIOS like a PC Bootcamp is used to boot Windows. But this also means you need Bootcamp to start the installation from the XP CD. As the previous poster said try a reinstall, but would suggest using Boocamp to format the XP partition first and then start the XP installer.
