I am trying to install Vista on a friends computer. I purchased the upgrade version from office max, and I tried to use the upgrade workaround in order to install a clean version without having to upgrade over windows xp. I was able to format the partition that xp was installed on, and installed vista successfully without entering a cd key. However, when I went to upgrade from within vista, I received a message that I needed at least 7 GB or something like that free in order for the upgrade to work. The total size of the OS partition is only like 7 GB total so I obviously do not have enough space. The total size of the hard drive is 80GB, with 60+ GB as the storage partition, and the rest for the OS. What would be the easiest way for me to get the required free space to perform the upgrade from Vista? I tried looking for vista compatible partition management software for vista, but none is currently available as far as I have seen. I am also aware of the fact that vista has built in capability to resize partitions, but when I click on the partition the OS is loaded on, there is no option to expand it using the windows partition management. Is there something I need to do in order to be able to expand the C: drive from within the vista management programs? Or should I just forget about trying to resize the partition and just burn all of his files to DVDs, wipe out the whole hard drive and start from scratch, making a larger OS parition?
