The PC MBR partitioning system only allows 4 primary partitions per
drive & you already had 3.
If the drive was partitioned with MBR, then you need to create an
extended partition as sda4 and then create the Linux partitions as
logical ones inside the extended partition.
The alternative to MBR on some modern machines is GUID.
If you boot off a LiveCD and run GParted, it should tell you.
I tend to recommend creating the partitions in advance with GParted
anyway - it offers more control & a better UI than the install
