I have a SATA HDD with XP pro on it. I have partitioned it in half and installed VISTA x 64 and have no problems. After doing the first update and re-booting, it goes straight in to XP and once there i can find no way of getting it to boot to VISTA going through the "My Computer, properties, advanced, start up and recovery then edit the boot file" there is absolutly no evidence of VISTA being installed. How can i get the choice of VISTA or XP back again.
