Running Win10 Home x64 on a system I built, but using a HDD from a
Lenovo that is out of use. I used the same OS installation- it found
and installed the drivers I needed for the new MB and CPU, and
everything runs like nothing was changed.
Opening Disk Management shows some extra partitions that I don't think
I need, but am not sure which ones to keep, and which to delete.
Here's a screen shot of DM:

If I right-click on any partition other than the Boot one, my only
option is "Help", which brings me to:

I'm willing to bet the OEM and the 30GB ones are from the Lenovo, but
how do I tell, and how do I get rid of them if they are?

Thanks!

I was able to use Mini Tool Partition Wizard to explore the contents of the
recovery partion on my system drive.
