Reinstalling Windows

You *must* install the AHCI driver for Vista (on your driver disk) when reinstalling Vista or your install will hang on the “Completing Installation” phase. When going through the Vista Install wizard pages, when you get to the page that asks you which partition you want to put the OS on, there is a button for Load Drivers or something like that in the lower left. Click that and shove in the Dell Drivers disk and select the AHCI driver for installation.
