Triple BOOT

I have my old PC set to Dual Boot Windows XP Pro (IDE Slave) and Windows
2000Pro (IDE Master) - No Problems

My new PC has Vista Ultimate 64bit running on 2 Dual mirrored 320gb Sata
Drives. In addition I have 2 older 40gb IDE drives. Like on my old PC I
installed Windows 2000 Pro on the Master (E and XP Pro on the slave (F. I
Use the boot drive menu to select the Boot drive. I have no problems booting
Vista or Windows 2000 Pro however I always end up with a NTOSKRNL.EXE error
when I attempt to start Windows XP Pro. I have re-expanded NTOSKRNL from the
Windows XP Pro install disk using the Recovery consul. I have also rebuilt
the boot.ini on the E: drive using the Windows XP Pro BOOTCFG /rebuild
command. Nither has solved the problem.

All assistance welcome.
