Hello every body,

I had Vista Ultimate x64 installed in my first partition

than I installed XP on the Second partition

when I did so the boot.ini has changed and ignored Vista completely so I don't get the OS Boot Menu, it boots directly from XP

the boot.ini didn't contain Vista:

Code:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional"
I added the folloing line:

Code:
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows vista"
the the OS boot menu appeared but when I choose Vista

I get the message:

Windows could not start because the following file is missing or corrupt.

<windows root>\system32\ntoskrnl.exe

Please reinstall a copy of the above file.
how do I fix this problem so I can boot Vista again?

Thanks in advance

Hi -

I would wipe the drive with KillDisk, then re-install XP 1st followed by Vista. The file mentioned in the error message is the NT Kernel.

KillDisk - http://www.killdisk.com/downloadfree.htm

Make bootable KillDisk ISO CD w/ ImgBurn -
ImgBurn - http://www.imgburn.com/index.php?act=download


However, you may find some help near the bottom of the 1st Microsoft Dual Boot info link -

I'm not sure there is...

When installing Windows OS's, you should always install the older first. But I wonder... If you make a complete backup of the drive via the Backup and Restore Center, store it somewhere, wipe the drive, install XP first, then restore the drive... Would the problem still occur?

The solution is much easier :wink:

Well, that may be a slight overkill... I guess that not all prefer my method of nuke first, ask...

Try this - http://support.microsoft.com/kb/919529

Thanks very much! that was really helpful

I used this method and it fixed it:

Note You can run the commands in the following procedure by using the command prompt. If you run these commands in Windows Vista, run them at a command prompt that has elevated user rights. To do this, click Start, click Accessories, right-click the command-prompt shortcut, and then click Run as Administrator.

1. Use Bootsect.exe to restore the Windows Vista MBR and the boot code that transfers control to the Windows Boot Manager program. To do this, type the following command at a command prompt:
Drive:\boot\Bootsect.exe /NT60 All

In this command, Drive is the drive where the Windows Vista installation media is located.
thanks again :wave:
