Archived - Boot Camp: "0x80070005" appears when upgrading from Vista to Windows 7

This article has been archived and is no longer updated by Apple.

Symptoms

With Boot Camp 3.1 or later, when upgrading from Microsoft Vista to Windows 7, an alert with error code "0x80070005" may appear. This can happen when the Windows 7 installer attempts to write to a read-only Macintosh volume.

Resolution

Use the Boot Camp Utility for Windows 7 Upgrade Installation Utility before upgrading from Windows Vista to Windows 7. This utility safely unmounts the read-only Macintosh volume on Microsoft Vista.

  1. Download the Apple_Win7_Upgrade.zip file.
  2. Double-click the zip file to uncompress it.
  3. Double-click on Apple_Win7_Upgrade_Utility.exe to start the utility.
  4. When "An unidentified program wants access to your computer" appears, click Allow.
  5. When "Boot Camp Utility for Windows 7 Upgrade installation" appears, click OK.
  6. When "Preparation was successful" appears, click OK to restart your computer.
  7. After your computer restarts, validate that the Macintosh volume has been removed by clicking Start > Computer.  The Macintosh volume should not be visible.
  8. Perform the upgrade installation from Microsoft Windows Vista to Windows 7.

Note: To remount the Macintosh volume while running Windows 7, insert a Mac OS X v10.6 (or later) Install DVD.  Click Boot Camp Drivers, then click Repair.

Additional Information

When installing Windows 7 on an iMac (27-inch, Late 2009) using Boot Camp, a black screen may appear.  This can happen because the Windows 7 installer does not include the necessary graphics or Bluetooth drivers for your Mac. See iMac (27-inch, Late 2009) displays a black screen during installation of Windows 7 using Boot Camp for more information.
