Ultimate Boot CD

Hi,
i've a problem with a notebook (an hp pavilion entertainment dv6000), i updated the bios driver and, after it shuts down, it cant enter in windows (xp) and will appear a blu screen for few seconds, i tried to enter in other ways but nothing, i cant enter in dos mode too.
I tried to do the recovery from the cd, but it wont find the hard disk, i used ultimate boot cd to recovery hard disk but it is the same "dido not find hard disk drive".
What happened? pls help me, thanx

Look in your BIOS and see if your Hard drive is visible there (see if you can find the name of your Hard drive).

What do you mean with a bios driver? Did you flash the bios?

yes, after flashing bios, it shuts down and wont work (it saved the old bios backup but i cant recovery, cause ultimate boot says "did not find hard disk drive").
The bios dyagnosis found the drive, but the boot disk not (i tried to do the scandisk-like utilities)

When you try to boot the hard drive (xp), is there any error message on the screen (write it down if there is any). Do you get the message directly when you try to boot? If the blue screen is from windows xp, the hard drive can be accessed else it can't display the message.
Write everything down (as far as possible) what you see at your screen, from the moment that you boot your pc and post it.

Normally if your bios can see the drive, other programs must see it also normally.

Try to boot your windows xp installation cd with the recovery option to see if it finds your hard drive.
You can try to burn an iso of 'Puppy linux" to see if your hard drive can't really be accessed.
