If the PC can't see the drive in the BIOS you need to fix that first.

If the BIOS shows it but Hirens doesn't I try my old standby GPARTED booted from USB or CD.
However why partition at all today? The idea of partitioning to save an OS or Apps has been dashed to pieces. And if I wanted to install say Windows then Linux I simply use Windows install's advanced menu to set the size of the partition during install (well covered so I don't duplicate it here.)
