Disk Utility will not display “Recovery HD” on it’s own because it’s a hidden partition, meaning you can’t just go into the app and delete it. What you can do though is format the entire drive though. This is sort of the nuclear approach but it works to delete the recovery partition too.
Boot the Mac from a recovery DVD, USB key, or an attached drive
Launch Disk Utility
Right-click on the Disk (not the partitions) and select “Erase”
Select the default Mac OS Extended (Journaled) as the file system, and give the drive a name
Click on “Erase” to completely format the drive – you will lose all data on the drive and all partitions.This formats the drive giving you a clean slate to start from.
to make sure you may use terminal command before and after format
this will display all the partitions on your disk

Thanks for the help Munas, i knew that you could not see the hidden partitions from disk utility, what i wanted to know was what was the best way to wipe all those partitions out (hidden or not) and you helped with that.

10 ??? !!!
just checked my macbook pro runing ML
it has 5 (I have two patitions) if you use single partition your results should contain 4 after the installation
Apple_HFS whatever you call it
Apple_boot Recovery HD
so since you have nothing on that disk I think it should be 1 or two at most...
what are the sizes of these partitions and are you sure you are looking to the computer disk partitions and not USB or what you have booted from...?
How many /dev/diskX you have ?

(Hard drive 250GB)
(USB Drive 8.1GB)
Apple_HFS Mac OS X install ESD
(Dont Know 1.3GB)
Apple_HFS Mac OS X Base System
now from this point on
/dev/disk3 - /dev/disk13 are all untitled partitons rangeing from 524K to 6.3MB

I think that /dev/disk0 is the disk on your Mac
all the rest is on your boot device, USB probably...
check the size of GUID_partition_scheme on /dev/disk0 it should be the size of your Mac disk
if yes, than your are fine and it is time to start installation
