Can't boot Windows XP Professional

[5er000]

Can't boot windows XP.
I'm new here.
When I start my PC, Windows XP don't boot.
I tried to boot in safe mode, nothing.
I tried the recovery console, nothing (there is this message: Widows stoped for preventing any damage to your pc(or somethig like that)).
When I scanned the PC with a live CD anti-virus, it seemed that the hard disk is gone.
I was rigth the hard disk is unloccated (unrecognised disk label- gparted).
The registery is missing too.
Can i still backup my files?
I searched in the web, but I didn't found nothing.
Can somebody help me??
Please, help!!
Thanks in advance

Possible hard drive failure. Test it with a bootable CD containing the drive maker's diagnostic software for DOS. Create the CD and boot your PC from it. The download links are here: http://www.tacktech.com/display.cfm?ttid=287

Thanks a lot, I discovered that the hard disk is burnt(destroyed).
And i probably must change it(replace). I will try that live CD anyway.
