I have a TamilNadu Government laptop Lenovo B460e. First when I got it, it had dual boot (grub) for Windows 7 and Linux .The harddisk size is 320GB. I deleted those OS and installed new Windows 7 because of some problems. It's working fine.
From the start I was able to use only two partitions System (c:) and Logical(d:). Now when I checked my diskmanagement I have 3 partitions. It had a 3rd partition without any name or letter or type. It had nearly 95GB free space. Its status says "Healthy(primary Partition)".
When I try to delete the partition, it says "This partition is not created by Windows. Do you really want to delete?". I definitely need some extra GB because my drives are already full. Would I be able to use that 95GB if I delete that partition and will it lead to any problems?
