Hello Everybody
Just wanted to share my new experience.
If your system fails to start due to an error corresponding to missing HAL.DLL, invalid Boot.ini or any other critical system boot files you can repair this by using the XP installation CD. Just boot from your XP Setup CD and enter the Recovery Console. Then run “attrib -H -R -S” on the C:\Boot.ini file and remove it. Run “Bootcfg /Rebuild” and then Fixboot

Hello Everybody
That’s me again.
This time we will learn how to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and restore often startup mistakes in Windows Vista.
INTRODUCTION
You can use the Bootrec.exe utility in the Windows Recovery Environment (Windows RE) to troubleshoot and fix the following items in Windows Vista:
-Master boot record (MBR)
-Boot sector
-Boot Configuration Data (BCD) store
Note: When you are troubleshooting startup errors by using the Windows RE, you should first try the Startup Repair option in the System Recovery Options dialog box.
If the Startup Repair option does not resolve the issue, or if you must troubleshoot more steps by hand, use the Bootrec.exe utility.
MORE INFORMATION
To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:
1.Put the Windows Vista installation disc in the disc drive, and then start the computer.
2.Press a key when you are prompted.
3.Select a language, a time, a currency, a keyboard or an input method, and then click Next.
4.Hit Repair your computer.
5.Hit the operating system that you want to repair, and then click Next.
6.In the System Recovery Options dialog window, click Command Prompt.
7.Type Bootrec.exe, and then hit ENTER.
Good luck with your Windows Vista, since with this OS your still need it.
Cheers,
Carl
