Hi :)
I would like to first ask how you exactly updated Vista "was this a security patch you recently installed?", or what part of Vista did you update when the Dual Booting error occurred?

sorry sp1 for vista

Hi RTFire. Since Microsoft has not officially released Service Pack 1 for Windows Vista, I would strongly advise you to uninstall the SP1 update you installed and wait until Microsoft officially releases the SP1 to the public.

I have uninstalled sp1 and am still having the problem

I have some questions for you:

- What is the exact error message you received?

- Are you using valid copies of both Windows XP and Windows Vista?

- Is each Operating System on separate drives or partitions within the same drive?

[rtfire1]

both copys are valid. I have the copys on two diffrent partitions, vista is on the c drive xp64 is on the f drive.

I forgot the paper I had writen the error msg down on at my home (sorry). I will post it to night as long as the kids don't need to much help or pc time with home work.

thanks for your questions

Okay, depending on your level of expertise, you have three options:

- The Scan Now Command

- Repair Drive within Windows Setup

- The Recovery Console

Most of us within this forum avoid providing suggestions regarding the Recovery Console simply because this utility is for highly trained/skilled technicians. However, here are all three options. Please use caution in choosing the option you feel is best for you:




Scan Now

- Insert your Windows XP CD into the drive. If Autoplay kicks in, exit out of it

- Click on Start -> Run

- Copy and Paste this text within the text box: sfc /scannow (note the space between the sfc.........and............the /scannow)

- This command will initiate Windows File Protection Service to scan all protected files and verify their integrity, replacing any files with which it finds a problem

Be patient and allow this process to proceed completely. This will take some time. Once this process is completed, your computer will restart.




Repair Within Windows Setup

- Restart the computer

- As soon as the computer begins to boot up, access the BIOS setup screen. If you are not sure how to access the BIOS, follow the steps within this Document so you can change the Boot Sequence to the optical drive first.

- Once this process is complete, restart the computer

- As the computer begins to restart, you will be prompted to press any key to boot from the CD/DVD...tap the space bar

- Once the Welcome to Setup screen appears, press Enter to continue the Windows Setup program. After you accept the license agreement, Windows searches your hard disk for an existing installation of Windows. If it finds such an installation, it offers a menu that includes a repair option. Press R to perform the repair. For you, I would presume it would be the F: partition.

- If the drive and Windows are repairable, this process will work to restore Windows AND your files that are salvageable.




Recovery Console - Use at your Own Risk

- Follow the same first four steps as with the previous option

- Once the Welcome to Setup screen appears, press R to continue with the Recovery Console

- After a short period, your screen will go black and you will see the following message:

Microsoft Windows® Recovery Console

The Recovery Console provides system repair and recovery functionality.
Type EXIT to exit the Recovery Console and restart the computer.

1: C:WINDOWS

Which Windows Installation would you like to log on to
(To cancel, press ENTER)?

For your situation, as I learned not too long ago, you will have two options since you have two Operating Systems. Select the option associated with C:WINDOWS.

- Next, you will be prompted for the Administrative Password. If there is no Administrative Password, just hit Enter

- Once you have full access to the Recovery Console, type this exactly as it appears

cd c:windowssystem32

copy "..driver cachei386ntoskrnl.exe"

- You will be prompted if you want to overwrite the existing file, press Y and Enter

- If you receive a File Not Found Error, confirm you have the correct path and spelling. If you do, try this command:

cd "c:windowsdriver cachei386"

expand sp1.cab -F:ntoskrnl.exe c:windowssystem32

- Again, confirm that you want to overwrite the file

- Type Exit to end the Recovery Console
