ok. i have a problem. i had windows vista 32 on my main hard drive. i added a second hard drive and installed windows vista 64 on that one and when i tried to log back on to the 32 bit after install it said that the windows installation was not genuine. in reduced functionality. when i boot back on to the 64 bit everything is all good but thats not my main installation. someone told me to use diskpart to assign the partition on my main 32bit installation to the active partition. i tried to learn how to do it but it keeps saying invalid command or something. need help on doing this.
