I installed windows vista on a 40 GB partition and i have another 40 GB partition free. when i went into diskmgmt.msc and tried to create a new simple partition, it gave me an error saying that there is no free space. i have a 160 GB HDD and right now there are 3 partitions in it. But in diskmgmt.msc, i can see that there is a 40 GB free space but i m unable to create a new simple partition.
Any comments as to how can i make use of that free HDD space?
