Install problem

If all four are primary partitions then you've hit the limit set in your 
hard disk's MBR.  Any individual hard disk only has enough space in it's 
partition table (stored in the MBR) for four entries. Each primary 
partition takes up one entry. An extended partition also takes up one 
entry, but may be further sub-divided into logical drive (but this 
information is stored within the extended partition itself).

The above limit exists regardless of operating system, therefore this is 
not an ubuntu issue per say.  The easiest solution would be to free up 
(i.e use/overwrite) one of your four partitions.  Provided you don't 
choose your XP partition, XP should be fine.
