Atapy.sys blue screen of death now can't boot

[unpwnntent]

This has got to be one of the worst errors I've seen in a LONG while.
A friend of mine owns a Dell Inspiron 8200 Laptop and last night was the first night that we tried to burning pictures onto a DVD+R.

The problem with the laptop the first time around was that it wouldn't recognize the blank disc. A CD-R disc of the pictures worked on the laptop and we were able to extract the pictures onto the Hard Drive but DVD+R discs never seemed to work.

After several tries to get the drive to recognize the disc (ejecting, re-inserting), a blue screen came up.

Now the second but worst problem is that now my friend can't boot up to Windows XP. The CD/DVD Drive AND Floppy Drive AND Primary Hard Drive was no longer found. The only place I could've gone to was the BIOS, which I looked around in and those particular devices were greyed out, non-existant. DEAD.

The laptop has some important documents and files that my friend needs to gain access to, or at least try to back-up before entering a reformat if need be. I'm hoping this is just a hardware incompatibility problem but due to my inexperience with Laptops, all I can do is hope for the best.

If you guys can help me out with the dilemma it'd be much appreciated.

Thanks in advance.

Oh dear that sounds horrible. Is DVD-writer detachable from laptop itself? I don't know if you can but maybe you should try disconnecting ide devices one by one, I think one of them is dead or near dead and holding back the rest of devices. Just a guess tho.
