Unable to shrink partition in windows 7

Are you using the Windows drive manager? You cannot shrink a volume past the locations of files. Defrag the drive and try again.

Hi, as I know ever HP laptop has been partitioned into 4 primary partitions already from OEM, one for "system resvervd" partition, one for Windows OS, one for "HP-tool", and one for "Hp recovery partition". Therefore I think you need to repartition your hard drive, or you could not crate any more partitions. becasue as we know the mbr hard disk could support at most 4 primary partitions. If you keep createing more partitions then you will get the error message "the disk you select will convert to dynamic disk".

To repartition hard disk in Windows 7, You could refer to this article:
