Creating New Partition

I get an error message when trying to create a new partition on the hard drive using disk management. After creating an unallocated section I tried to create a New Simple Volume. After going through the paces it ends up saying that the basic disk will be converted to a dynamic disk and you wont be able to run os's or boot from the disk. Which is ok because I just want to store music pics, and some docs on it. I click yes , and then the error message reads. there is not enough space on the disk for this operation.

I would also like to know if I can change the allocated section to a smaller size.

Thanks for any help.

Can you purchase partition magic anymore?

ty everyone for posting so quickly

Yes and thanks to you I used the free shareware you recommended I actually bought the pro version because I had to merge two partitions together... Thanks again Britton.
