Hello! I viewed similar topics in this forum but did not find any that quite addressed my situation/questions. I recently installed Vista Home Premium 32-bit on my 74GB hard drive with a single full partition. A few weeks later when I got my Vista Home Premium 64-bit DVD, I used Vista to shrink my C: volume as much as I could (about 25GB), and created a new partition onto which I installed the 64-bit version. I have since found that all my programs and hardware work fine with the 64-bit version, so now I would like to delete the original partition containing the 32-bit version. My goal is to end up with only Vista 64-bit installed, and preferably have my entire 74GB drive as a single volume again. However, from what I have read, apparently the Vista boot loader is on the partition that I wish to delete (containing the first Vista installation). If I just delete the volume with 32-bit while running 64-bit, will I have problems the next time I restart since the boot loader is gone, too? Will booting from the 64-bit DVD restore the boot loader to the remaining Vista 64-bit installation? Do I even need to worry about the boot loader with only a single OS installed? Do I need to take any other steps? Any other advice, suggestions, links? Thank you very much in advance; this forum has always been most helpful!
