I think the problem is that you can only have 4 Primary partitions on a disk.
If you to convert one of the NTFS partitions to an extended partition, with
the NTFS partition inside it. Personally, if you want to keep the 4 drive
letters in windoz, I would back up the whole disk ("in case"), set up the
disk with 1 Primary NTFS partition and an extended Partition with the other 3
NTFS partitions inside it. Leave the free space as free space and let the
CentOS installer to use the free space as it sees fit
