Recovery partition help
Hello, I recently bought my HP laptop. The original operating system on this laptop was Vista, however the shop I bought it from installed Windows 7 RC before I bought the laptop. When my RC version expired awhile ago, i bought 7 Professional and did a clean install. My laptop has always had 4 partitions, 3 large ones and one small one named RECOVERY. It's about 14 GB in size with only 2GB left of free space. I never really knew what it was or worried about it. However, now I'm wondering if it's necessary to keep it. Do I need these files? Can I just delete the partition and allocate the space to another partition? Any help would be appreciated.
