Block DiskConfiguration of Vista SP1 64 bit not works rightly

[balubeto]

HI

I can not understand why the block <DiskConfiguration> </ DiskConfiguration>, placed in the autounattend.xml file located in the root directory of the DVD of Vista SP1 64-bit, is executed AFTER the display of the window of the partitions of the hard disk.

So, what is the trick to make sure that this block is executed BEFORE viewing this window?

THANKS

BYE
