If D:\ is an external drive this will not work without a sledgehammer and about 3 days of effort...

Look into VistaBootPro.

thanks for the reply,"d"is an internal drive.I read a lot on the site before posting and tried vistabootpro with no luck.

You're more than Welcome...and Welcome Aboard !

Another option would also be to purchase a 2nd drive and use your BIOS to switch between the 2 at startup time...cleanest method.
