We couldn t create a new partition error 0x8007045d

A frustrating error!

Error 0x8007045d typically occurs when trying to create a new partition on a Windows system. Here are some potential solutions to help you resolve this issue:

  1. Check disk errors: Run the built-in Check Disk (chkdsk) utility to identify and fix any disk errors. Open Command Prompt as an administrator and type:

    chkdsk C: /f

    Replace C: with the drive letter you're trying to create a partition on. This may take some time to complete.

  2. Disable Fast Startup: Fast Startup can sometimes interfere with partition creation. To disable it:

    • Press the Windows key + X and select Power Options.
    • Click on "Choose what the power buttons do" and then "Change settings that are currently unavailable".
    • Uncheck the box next to "Turn on fast startup (recommended)".
    • Save changes and restart your computer.

  3. Check disk space: Ensure that the disk has enough free space to create a new partition. You can check disk space by opening File Explorer, right-clicking on the drive, and selecting "Properties".

  4. Use the built-in Disk Management tool: Open Disk Management (Press the Windows key + R, type diskmgmt.msc, and press Enter). Look for the disk you want to create a partition on and right-click on it. Select "New Simple Volume" and follow the wizard to create a new partition.

  5. Use a third-party partitioning tool: If the built-in Disk Management tool doesn't work, you can try using a third-party partitioning tool like EaseUS Partition Master, Acronis Disk Director, or MiniTool Partition Wizard. These tools may be able to create a new partition even if the built-in tools fail.

  6. Check for disk corruption: Run the built-in System File Checker (SFC) tool to scan for and repair corrupted system files:

    sfc /scannow

  7. Reinstall Windows: If none of the above solutions work, you may need to reinstall Windows to start with a clean slate.

Remember to always back up your important files and data before attempting any of these solutions, as they may involve modifying your disk configuration.
