How to Fix Error 0x80300001 on Windows 11: Step-by-Step Solutions

Encountering error 0x80300001 on Windows 11 can be frustrating, especially when you are trying to install or upgrade your operating system. This error typically appears during the installation process when Windows cannot select the correct drive or partition for setup.

Fortunately, fixing this error is usually straightforward with a few simple steps. Understanding why the error occurs helps in applying the right solution effectively.

In this article, you will find easy-to-follow instructions to resolve error 0x80300001 and get your Windows 11 installation back on track.

Follow the steps carefully, and you should be able to fix the issue without needing advanced technical knowledge.

Quick Note Before You Start

  • Make sure your installation media (USB/DVD) is properly created and not corrupted.
  • Verify that your hard drive or SSD is correctly connected and recognized by your computer’s BIOS/UEFI.
  • Check if your drive has enough free space for Windows 11 installation (at least 64 GB recommended).
  • Back up any important data before performing disk-related operations to avoid data loss.

Step 1: Disconnect All Other Drives Except the Target Installation Drive

Sometimes, Windows gets confused when multiple drives are connected during installation. Disconnecting all other external or internal drives except the one where you want to install Windows can help.

  1. Turn off your PC.
  2. Unplug or disconnect any external USB drives, external hard disks, or additional internal drives.
  3. Leave only the primary drive connected.
  4. Turn on your PC and try the installation again.

This step helps Windows focus on the correct drive and reduces the chance of the error appearing.

Step 2: Check and Change the Boot Order in BIOS/UEFI

Sometimes the error occurs because the installation media isn’t set as the first boot option or the system is trying to boot from the wrong device.

  1. Restart your PC and enter BIOS/UEFI settings by pressing a key like F2, Del, or Esc (check your PC manual for the exact key).
  2. Locate the “Boot” or “Boot Order” menu.
  3. Make sure your USB drive or DVD with Windows 11 installation media is set as the first boot device.
  4. Save changes and exit BIOS/UEFI.
  5. Try running the installation process again.

Setting the correct boot device ensures your PC loads the Windows installer correctly.

Step 3: Format the Target Partition or Create a New One

If the partition you are trying to install Windows on is corrupted or formatted incorrectly, error 0x80300001 may appear. Formatting or creating a new partition can fix this.

  1. On the Windows installation screen, when asked where to install Windows, select the partition you want to use.
  2. Click on Delete to remove the existing partition (make sure you have backed up your data).
  3. After deleting, select the unallocated space and click New to create a new partition.
  4. Click Format to format the new partition.
  5. Proceed with the installation on this newly created partition.

This process ensures the partition is clean and ready for Windows installation, which eliminates many common errors.

Step 4: Use Diskpart to Clean the Drive (Advanced but Effective)

If formatting through the installer doesn’t work, you can use the Diskpart tool to completely clean the drive and remove any hidden partitions or formatting issues.

  1. On the Windows setup screen, press Shift + F10 to open the Command Prompt.
  2. Type diskpart and press Enter.
  3. Type list disk and press Enter to see all connected drives.
  4. Find the number of the target disk (usually by size).
  5. Type select disk X (replace X with the number of your target disk) and press Enter.
  6. Type clean and press Enter. This will erase all data on the disk.
  7. Type exit twice to close Diskpart and Command Prompt.
  8. Go back to the installation screen and refresh the drive list.
  9. Create a new partition and proceed with installation.

This method fully resets the drive, helping to remove any underlying issues causing the error.

Step 5: Check for Hardware Issues

If the error persists, there might be a hardware problem with your drive or cables.

  • Try using a different SATA or power cable to connect your hard drive or SSD.
  • Test your drive on another computer if possible.
  • Run the PC’s built-in diagnostics tool (often accessible via BIOS/UEFI) to check for hardware faults.

Hardware problems can prevent Windows from installing correctly, so ruling this out is important.

Alternative Methods

If the above steps don’t solve the problem, you can try:

  • Creating a fresh Windows 11 installation media using the official Microsoft Media Creation Tool.
  • Updating your BIOS/UEFI firmware to the latest version available from your motherboard manufacturer.
  • Using third-party partitioning tools like MiniTool Partition Wizard to clean and format the drive before installation.
