The Computer Reboots in the "Installing Devices" Section During a Windows XP Upgrade (311839)


The information in this article applies to:

  • Microsoft Windows XP Professional
This article was previously published under Q311839

SYMPTOMS

When you are upgrading from Microsoft Windows 2000 Professional to Windows XP Professional, your computer may reboot during the "Installing Devices" section of Setup.

CAUSE

This issue can occur if your computer contains the NLynx PCI Twinax adapter (this is an AS/400 emulator adapter). When Windows loads the driver (Nltwinax.sys) for this adapter, the driver causes an error and the computer reboots.

WORKAROUND

To work around this issue:
  1. Boot your computer by using an MS-DOS or Windows boot floppy disk.
  2. Rename the Nltwinax.sys file in the %SystemRoot%\System32\Drivers folder.
  3. Reboot the computer and continue installing Windows XP.
  4. Click Cancel in any dialog box that prompts you for the location of the Nltwinax.sys driver.
