I have a 100GB hard drive. I am only using 11 GB of it right now. Can I use partition magic to make a seperate partition to do a dual boot of Vista on, And also another partition to do a Norton Ghost backup of my current hard drive. I know it would be better to put it on a seperate hard drive, I just lack the space to do that right now. 1. How big should I make the Vista Partition?? 2. Are there any disadvantages to backing up the hard drive image to the same physical hard drive (different partition) besides the possibility of the hard drive failing? 3. If I have a total of 11 GB used right now, I wouldn't need to make the "Backup Partition" any bigger than that, correct? Thanks for your help.
