I think you need to do a start-up repair , this tutorial from bleeping computers explains how

http://www.bleepingcomputer.com/tut...

You may also not have a Full install disk , so this will do .


http://neosmart.net/blog/2008/windo...

Nb. you do not need to use a torrent downloader for this disc just
double click on the down loaded link and select the browser of choice .


Some people have reported problems when they have burned this disk with Nero , I have had no problems with Vista's burner or Cdburnerxp ,
just slow the burn speed down a bit ,

If start-up repair does not do it for you try system restore .

Or .

From a boot disk


Open a command prompt and type

bootrec.exe /fixmbr Press enter
bootrec.exe /fixboot press enter
bootrec.exe /rebuildbcd press enter

Type Exit then press Enter to close the command prompt.

Thanks Jack.

I downloaded and burnt Neosmarts Vista Recovery Disk. Opened Command Prompt and typed the 3 commands suggested by you. Tried to auto repair Boot. It failed. Now am unable to go to System Recovery Options anymore.

Any suggestions please?

... using the boot-up Recovery Disk go to Safe mode with command prompt

... when you get there (type):

bcdedit /enum [press ENTER]

... using this format anything listed as "unknown" under {**}

... ie... {bootmgr}
device <<<<<>>>>>>> unknown

... post here under the {relevant} << heading

... there maybe 3 unknown(s) @ most!

Is the hard drive detected in the bios ? You might want to run diagnostics on the HDD.

I booted with the "Neosmarts Windows Vista Recovery Disk".
System Recovery Window did not show any OS. Went to the System Recovery Options.Tried all the options, one by one. Entered into the Command Prompt and then tried the commands:
bootrec.exe /fixmbr Press enter
bootrec.exe /fixboot press enter
bootrec.exe /rebuildbcd press enter

but failed.

Now with this Disk also I can't gey into the above options. Windows starts booting with a progressing White Bar. Then moving cursor indicates Microsoft Windows loading and then the Screen turns Black with the movable Arrow Cursor.

Booting from C: Drive states that Windows failed to load because the HAL is missing, or corrupt.

File: \Windows\sysrem32\hal.dll

Status: 0xc0000098.

Any suggestions?

... First, Boot from the Vista cd/DVD

... Select your Vista Install from the list in Windows Boot Manager

· Microsoft Vista Setup (x86)
· Microsoft Vista Setup (x64)

...[press ENTER]

... you will then see Windows is Loading Files.

Next, the Language Screen will come up. Since you have already selected this option when you installed Vista, just click on Next.

Now you will see the Vista Installation Screen.

DO NOT CHOOSE Install Now

Instead, towards the bottom left of the window you will see.

· What to know before installing Windows

· Repair your Computer

Choose and click on Repair your Computer

You will then come to the System Recovery Options. Choose Microsoft Windows Vista from the list. Then click Next.

You will now have the option to choose which Recovery Tools you wish to use.

This list provides details to the five tools that can help you repair your Vista installation. These tools are:

1. Startup Repair

Automatically fix problems that are preventing Windows from starting:

Startup Repair is an automated repair process that scans your Vista installation for problems and attempts to automatically fix them. When you select to repair Vista from the Vista setup screen, and Vista detects problems, this process will be started automatically. You can cancel this process at any time to access the other repair tools described below. The Startup Repair process has already been introduced above when we discussed performing an automated repair.

2. System Restore

Restore Windows to an earlier point in time:

System Restore allows you to restore your computer's configuration, driver information, and programs to a previous state while leaving your existing data intact. Using this option can typically fix a installation's problem if it is not associated with faulty hardware. In order to use this option, you must have had System Restore enabled in Vista so that there are restore points available to restore to.

3. Windows Complete PC Restore

Restore your entire computer from a backup:

Complete PC Restore is a feature that allows you to restore your entire computing environment from a backup image that you created previously. The ability to create backup images for Complete PC Restore is only available in Windows Vista Business, Ultimate, and Enterprise. If you have tried all possible steps to repair your computer, and have a Complete PC Restore backup image available from when your computer was operating properly, then you can use this repair option to restore that image.

4. Windows Memory Diagnostic Tools

Check your computer for memory hardware errors:

Windows Vista comes with a diagnostic tool that allows you to check the memory installed in your computer for errors. This will allow you to determine if the actual memory (RAM) hardware installed in your computer is creating errors.

5. Command Prompt

Opens the Command Prompt window:

The Command Prompt repair tool allows you to open a command prompt that you can use to access the files and registry information on your computer. This is an invaluable tool for removing security threats such as worms, rootkits, and other malware from your computer and to be able to access files when Vista fails to boot up.

You still have not answered: But can you get into the BIOS by hitting the appropriate key ?
You may have to set the BIOS to boot from CD/DVD before the HDD.

... " kx5m2g" according to Response Number 4 "udoctor" seems to imply that he/she had booted-up with the downloaded repair only cd

... which seems odd that one can not now and access the command prompt!
