When you encounter an "Access is denied" error while trying to shrink a volume for dual-booting Vista and Windows 7, it typically indicates that there are some restrictions preventing the system from resizing the disk space. Here are a few possible reasons and solutions for this issue: 1. Administrative Privileges: - Solution: Ensure that you are logged in with administrative privileges. Regular user accounts might not have the necessary permissions to perform disk management tasks. 2. Disk Fragmentation: - Cause: Fragmented files or unmovable system files could be blocking the partition from being resized. - Solution: Run a disk defragmentation tool to consolidate free space and make it easier to resize the partitions. 3. Page File or Hibernation File: - Cause: System files like the page file or hibernation file may be located at the end of the partition, preventing resizing. - Solution: Temporarily disable the page file and hibernation file, shrink the volume, and then re-enable them. 4. Third-Party Disk or Security Software: - Cause: Third-party disk management or security software might be interfering with the resizing process. - Solution: Disable such software temporarily and attempt to resize the partition again. 5. File System Errors: - Cause: File system errors on the drive can prevent partition resizing. - Solution: Run a disk check utility (chkdsk) to scan and fix any file system errors on the drive. 6. Boot from Installation Media: - Solution: If attempting to shrink the system partition, consider booting from installation media (like a Windows installation USB) and using the disk management tool from there. Before proceeding with any changes to the disk partitions, it's crucial to back up important data to prevent data loss in case of unexpected issues during the process. Try these solutions sequentially to resolve the "Access is denied" error when shrinking the volume for dual-booting Vista and Windows 7.
