When you copy the files contained in the i386 folder on the Windows XP CD-ROM to a folder on your computer's hard disk and then attempt to upgrade your computer to Windows XP (also known as installing from a flat), you may receive one of the following error messages.

•	When you upgrade a Windows XP-based computer: The installation source path specified in Setup is invalid. Contact your System Administrator.
•	When you upgrade a Microsoft Windows 2000-based computer: The option to upgrade will not be available at this time because Setup was unable to load the file drive:\i386\WINNTUPG\NETUPGRD.DLL. The system could not find the file specified. NOTE: drive is the letter of the CD-ROM or DVD-ROM drive that contains the Windows XP CD-ROM.
•	When you upgrade a Microsoft Windows 98-based computer: Setup has disabled the upgrade option. Could not load the file drive:\i386\win9xupg\w95upg.dll Setup cannot continue, because this version can only install as an upgrade.

This behavior occurs because Windows Setup requires additional files and folders to be present in the installation directory.

To resolve this issue, copy the entire contents of the i386 folder (including subdirectories) from the Windows XP CD-ROM to a folder on your computer's hard disk, and then restart the installation.

To copy the i386 folder from the CD-ROM while in Windows, open your computer's CD-ROM or DVD-ROM drive, right-click the i386 folder, click Copy, and then paste the folder to a partition that has enough hard-disk space.

To copy the entire i386 folder if you are not able to start Windows, use a Windows 98 or Microsoft Windows Millennium Edition (Me) Startup disk to start your computer, and then use the Xcopy utility. To do this, use one of the following methods, as appropriate to your operating system.
