Presario v6130us Blue screen after bios update

Hello to all. This is my first post here.
My troubles are as follows:
I started working on a presario v6130us laptop with a blue screen. The owner thought it was due to a virus when she opened a email. I went and wiped the HD and reinstalled windows XP pro. Had the darn thing working nicely.

Then I thought he computer was running a lil slow, so I decide to update the bios. From (I believe) v.07 to ver.29 from the hp website. At the restart, it never restarted, so I restarted it by pressing power button. Went into the same ol blue screen loop. The stop message is 0x0000007b. I looked that variable up on the microsoft webpage. It says it is a Win 2000 unmountable boot device. Prior to this message it was Stop 0x000000ED.

Does anyone know how to roll the bios back, or what could be causing this problem? I have done a quick HD test. so far it has passed and is now doing the "executing" test @ 20% complete. B4 the bios update, the test would say FAIL 1- 07.

Like I said, once I reinstalled windows, the computer was working fine.
Any help and or suggestions are very well appreciated.

Darnit

 

How does a person go into bios to check the HD settings. It is like something is being disabled or changed re HD. I cannot go into the bios settings for this laptop to change "type" of HD settings. I am not a computer PRO, but have some knowledge to settings and procedures. Like I said in the previous post, it was working fine until I loaded the new bios file.

Thank you in advance
Blessings

 

There is a possibility that the BIOS update changed the HDD settings but they aren't user accessible, the BIOS on laptops is usually locked down, there's nothing but the most basic settings available.

However, an unmountable boot volume error indicates a failed hard disk. Slow performance without apparent cause is a symptom of a drive that's about to fail, so i'd say that there's 80% possibility of the HDD being shot. Try another drive. The fact that it died after the BIOS update could simply be a coincidence.
