Logical partitions are partitions contained in another bigger partition, called "extended" partition. Obviously, your secondary drive contains one big extended partition with one or more logical partitions in it.
Primary partitions must be located outside the extended partition, so you can't just transform or rename a logical partition to primary. You have to delete or shrink one or more of the logical ones, then shrink the extended partition and so create the unallocated disk space for your new windows partition.
You can use for this the Gparted livecd. You have to download the ISO file, to burn it on a cdr or cdrw (as IMAGE ISO CD, not just as data cd), and boot from it. To do this, you have to adjust the boot sequence in the BIOS setup to look first the cd or dvd drive. It is better to backup important files and data from the drive, because any partition work is potentially dangerous.
After booting from the live cd you can view the existing partitions. Then you can make a screenshot that you can post here, for further instructions.
It is better to read the documentation before doing any disk change:
