Somehow my drive has ended up with three partitions: an unnamed 86 MB partition labeled "Healthy (EISA Configuration)", an unnamed 10 GB partition labeled "Unallocated", and finally a 222.8 GB NTFS partition named "OS (C:)" and labeled "Healthy (System, Boot, Page File, Active, Crash Dump, Primary Partition). I have done some research online and learned that the EISA partition is important and should be kept, and Disk Management won't let me delete it anyway. I don't really care about that as it is only 86 MB, though I would be interested in knowing exactly what it is for. What I do care about is the 10 Gigs of unallocated space. How do I merge it into my C: drive? Disk Manager says it won't extend into space before a partition, but this is what I want to do. Is it possible to recover this space WITHOUT messing up my OS or any of the data in C:?
Again, I don't want to make a bunch of partitions, or run multiple Operating Systems, or anything like that. I want to run as few partitions as possible with one OS and one drive letter. I simply want to turn "EISA|Unallocated|OS (C:)" into "EISA|OS (C:)". How do I do it?
