Use the Recovery Disc supplied with this system

To repair the OS by using the Repair Option.

If you do not have a Recovery Disc only a Recovery Partition you need to use a Live Linux here to boot from and save your Data then invoke the Recovery Partition to rebuild the system to As New. You can either download a Live Linux from here

I recommend Knoppix for this but any will suffice or go into your Local Newsagent and buy a Linux Mag with a OS on the Cover CD and use that.

Boot from the Vista CD and on the first screen click Next, click Repair your computer, click Next and select Command Prompt and then run the Bootrec tool.

OK

by Jacky Howe In reply to am Using vista 64 bit DVD ...

You shouldn't be using that DVD on a 32Bit Operating System. Try the other methods suggested to retrieve your Data. If you use the Vista Recovery CD you can Backup to a USB external hard drive if you can access the Data.

Hp Dv6570ee Test the hard drive
Many PC startup problems are caused by minor errors in the software that controls the storage of files on the hard drive. The HP Hard Drive Self Test will detect and repair these errors but will not produce a detailed report of all the actions taken. For the test to run, there must be good physical connection between the hard drive and the computer. If the computer is dropped or jarred, the hard drive may moved and disrupted the connection, and that will cause the test to fail or may even prevent the test from starting.
You may want to try running the HP Hard Drive Self Test, but if it fails, see the section on Removing and Reinstall the Hard Drive, and then repeat the Self Test.
Use the steps below to test the hard drive for errors by using the HP Hard Drive Self Test.
1.Plug the AC Adapter into the Notebook PC.
2.If the PC is on, press and hold the Power button for 15 seconds to turn off the PC.
3.Press and release the Power button to turn on the PC, and immediately press the F10 key repeatedly to open the BIOS setup window.
4.Use the Right Arrow key to select the Tools or Diagnostics menu.
NOTE: Your BIOS version may use slightly different names for menu items.
5.Select Hard Drive Self Test .
6.Press the Enter key to start the test.
The self test process may include both a Quick test and a Comprehensive test. It also provides an Estimated test time .
If all of the tests pass, the hard drive is not damaged.
If any test fails , contact HP service and support for instructions.
After the Hard Drive Self Test is complete, restart the PC to verify that the problem is repaired.
Removing and Reinstalling the Hard Drive
If the computer was dropped or jarred, you may have to remove and reinstall the hard drive before running the HP Hard Drive Self Test.
CAUTION: To prevent damage to you computer, it is necessary to remove the battery prior to removing the hard drive.

Removing the battery.
1.Slide the battery release latch to the release position.
2.Slide and hold the battery locking latch to the unlocked position.
3.Slide the battery out of the battery bay.
Removing the hard disk drive.
1.Loosen the captive Phillips-head screws that secure the hard disk drive cover to the bottom of the notebook.
2.Use your finger or a flat-bladed tool to lift the outside edge of the hard disk drive cover and remove it.
3.Loosen the captive spring-loaded Phillips-head screw that secures the hard disk drive.
4.Grasp the Mylar tab and pull the hard disk drive toward the outside edge of the base enclosure to disconnect the hard disk drive from the system board connector.
5.Lift the hard disk drive out of the bay and remove.
To reinstall the hard disk drive.
1.Place the hard disk drive into the hard disk drive bay.
2.Push the hard disk drive toward the inside of the base enclosure until you make sure the connector is seated properly.
3.Tighten the captive spring-loaded Phillips-head screw that secures the hard disk drive.
4.Toe the hard disk drive cover into the enclosure.
5.Tighten the captive Phillips-head screws.
Reinstalling the battery.
1.Slide the battery into the battery bay until it is properly seated and the locking latch clicks.
Reinstalling the Windows operating system on the hard drive
If removing non-system disks and performing an HP Hard Drive Self Test does not resolve the boot errors or black screen error, it may be necessary to reinstall the Windows Vista operating system (OS). You can reinstall the operating system by either:
using the HP Recovery Manager to recover the OS from the recovery partition on the drive, or
using the recovery discs you created when you started using your notebook.
