Can't start Vista. BIOHD-4 error Unitialized/corrupt boot structure detected

I am trying to fix a computer for a friend. It won't start up Windows. It is a HP Pavilion a6319fh and has Vista on it (I'm not sure which version and the user doesn't know). The pc starts and gets as far as a blue screen (not the BSOD, but a deeper blue), the mouse works, but Windows won't load. I have tried to use a Start-up CD, the Vista Boot Disk created by the user, the System Restoration from the recovery partition of the hard drive, all with exactly the same result. I have tried to boot off a Windows XP CD, and the CD started loading windows files, then erred with a BSOD stop code 7B. The hard drive is a Seagate ST3360320AS.

I am able to run the HP diagnostic and get the error code BIOHd-4 "Uninitialized/corrupt boot structure detected."

I am able to boot in Ubuntu, and access files on the hard drive, but I don't what, if any, changes to make or which files to modify.

How can I get this pc running again?

Corrupt boot structure means that partition boot record has been corrupted. Was there any virus attack? The inability to load Windows desktop indicates that you have corrupt file system or even Windows hive.
As for 7b BSOD, your Windows XP simply has no drivers for this hardware. Change in BIOS the hard drive mode from AHCI to SATA or better to IDE. Since then Windows XP will load without BSOD.
Check the drive for viruses from Kaspersky boot CD. Or connect the drive as external via USB enclosure to another working machine and scan it for viruses.
If you eliminate the virus possibility first then we can give more instructions on fixing boot problems.

OK. I checked for BIOS and/or hard drive firmware updates, but there were no applicable ones. I chatted with a HP representative, who told me I needed to change the hard drive. But, before I do that, I changed the BIOS so the hard drive mode is set to IDE. At least now I am able to start loading XP. I have gotten to the point of formatting the hard drive. It is formatting, but taking forever (it took over 10 minutes to reach the 1% mark). But, I'm giving it a try. I will let you know. At this rate, it could be quite a while before I know the result. Thank you. I will keep you posted.

BTW, you can test the HDD surface before replacing it. Find out the model and vendor of HDD and go directly to their website. Find there check util in Support - downloads section and download CD image. Boot from it and perform several tests. If the HDD is on its way to mech churchyard then it is easier to replace the drive as HP recommended.
Also do you understand that reformatting will erase data on the partition?

OK. I'll do that. I have located their website.  I understand about erasing data on the partition. I have the original operating system to load on the disk.

Sorry, guess I wasn't clear. The result was a solid blue screen not the BSOD kind of blue, the kind of blue that sometimes appears prior to the display of the desktop. No errors, just no Windows.

I did get it fixed by doing the following somewhat convoluted steps: As Noxcho suggested, I first changed the BIOS so the hard drive mode was set to IDE (it had been set to RAID). I then booted up with my Windows XP CD, formatting the hard drive. I started to worry that the formatting took so long -- 2 hours -- but, I was able to successfully load XP on a newly formatted partition. The drivers were not loaded (there are no XP drivers for this system), but Windows loaded enough so that I could then re-install Vista using the 3-disc set of Vista boot disks. Vista has installed successfully.

Fortunately, the user (this is not my system -- I have been trying to fix it for my friend) has backed up her data files. I have reset the hard drive mode to RAID and the system seems to work fine.

Thank you all!

Frazier217, you need to get the BIOS update file from vendor and use it from USB or diskette. Find exact instructions at BIOS or motherboard vendor web site.
