I'm making a bit of space on my laptop as I'm running out of storage and so decided to delete the recovery partition (10GB) as it's for Win Vista and I've put Win 7 64 bit on it already. I've deleted that partition but I cant extend the C: into it so I'm guessing one of the other two partitions are in the way, one says Healthy (OEM partition) 110MB and the other says Healthy (primary partition) 2.5GB

Can I delete these partitions? I haven't created them myself and they aren't visible/useable in windows.
