"Stop 0x0A" After Windows Is Already Installed
If you receive the "Stop 0xA" error message after Windows is already installed, use the following troubleshooting steps.

Remove any Recently Installed Third-Party Software or Drivers
If you have installed any third-party software or drivers, you may want to remove or disable them from loading. Reboot to see if the software or driver was causing the error message. If so, contact the vendor of the software or driver to report the problem.

If you are not able to boot into Windows after you have installed the software or drivers, you need to use one of the following methods to restore Windows:
 * Try the Last Known Good configuration by pressing SPACEBAR during startup when you receive the prompt. When the Hardware Profile/Configuration Recovery menu appears, press L to switch to the Last Known Good configuration, and then press ENTER.
 * Repair the Windows installation with the Emergency Repair Disk or use the Windows Emergency Repair process.
 * If Windows is on a FAT partition, boot to MS-DOS and rename the problem software or driver.

Remove Any Newly Installed Hardware
If you have added any hardware since Windows was installed, you may want to remove the hardware to see if the error message stops occurring. If this corrects the problem, you may want to use any or all of the following methods:
 * Obtain updated drivers (if any) for the device.
 * Call the vendor to see if there are any known issues with the device.
 * Run diagnostics to see if the device is working properly.
 * Check Event Viewer for any additional error messages that might help determine the device or driver that is causing the problem.
