well,

SYSTEM,
c:WINDOWS 283gb
d: RECOVERY 14,3gb
e: HP_TOOLS 99,3 mb <---delete this partition

and then i was able to shrink c: partition without the error of converting dynamic to basic, simple, with no problems.
what i hate is the lack of information about it. Compaq dont put any info in manuals and even in there websites they dont talk to much about it...

It looks like almost all compaqs with WIN 7 has the same "problem" if anyone get a new Compaq, you now what to do...
