IMO buy a new HDD/SSD and add it to your system; this avoids any complications which may arise from removing a OEM partition. (If its a laptop which i think it is; google your model and see if it supports a second HDD)
That said my experience has been that removing the OEM recovery partition only screwed up my ability to "recover" the pc, but I downloaded all the drivers from their site and did a full reformat.
