partition ??

The only one you want to add to C is the green Extended partition, delete it then extend C into the un allocated space.

Don`t touch the others.

Make sure there is no data on it first, (even though it says free space) if there is copy it over to C before you delete it or you will loose it.

We have no idea what the last partition 3.72 GB is for. Is there data on it ? Did the pc come this way ? Did you create it ?

I believe there r linux mint files on those partitions due to a bad Install of linux. when I Installed linux I chose the option "something else.". partitioned myself out of windows. I eventually got back to windows thru macrium reflect. the attachment shown here Is not the original copy of windows, but what Is left after re-store. thank you.
