in case of SCCM error 0x800700A1 do the following:

diskpart
list disk                (list all disks on system)
select disk 0            (0 being the disk to setup)
clean                    (wipes the disk)
create partition primary (creates windows partition)
select partition 1       (selects the first partition)
format quick fs=NTFS     (sets format of primary partition)
assign letter C          (assigns the drive letter to "C")
exit                     (exits diskpart)
