Can’t install Windows XP 64 bit OS

I trying to install Windows XP 64 bit OS on to my Lenovo R500 laptop. I have Intel core 2 P8600 processor (64 bit cpu) and 4 gb of ram. I have a 500 gb harddrive and am currently running Windows 7 Ultimate.

The installation starts as usual loading all of the drivers and files and when the bottom of the screen message says, “starting windows” I get a blue screen error message that says, “check hard drive, run chkdsk /f , if this is first time reboot, check for virii” etc.

The error is 0x0000007B!

What is that and how do I get around it?

thanks
