This disc can not be partitioned because it is impossible to move some of its files.

Question

my boot camp do not work "This disc can not be partitioned because it is impossible to move some of its files." what to do? is there a way to partition mac without boot camp

Answer 1

Hard drives write data from the top down, if you delete data it doesn't magically shift upwards so there is remaining data on the lower part where BootCamp needs to go.
Apple has not resoved this issue when creating Bootcamp partitions for you, and likely they never will.
The only option is to use a blank powered external drive and (free) Cabon Copy Cloner your OS X partition to the external drive (default settings fine), then reboot holding the option key down so you can select this external drive to boot from.
Once you have marveled at the coolness factor of a bootable clone, you have to erase the internal OS X paritition using the Disk Utility > Zero erase  (one step below max security on 10.7) and once that's finished, to use Carbon Copy Cloner to clone the clone to the internal OS X partition.
Once you do that you can boot the comptuer normally and then easily create the Bootcamp partition.
It's a pain, but it's the only way to shift ALL and ANY data upwards on the OS X partition to make room for BootCamp, which starts at the bottom and works upwards until it hits OS X data.
Siince your OS X data is hit pretty fast, below the minimal BootCamp requirements for Windows 7, this is why it's not being created.
Hope that explains your issue.
If it went over your head, perhaps you need to have a professional install Bootcamp and perform this function for you.
