JSI Tip 2249. Windows 2000 setup issues 'No Valid System Partitions Exist'?

If you upgrade, or do a clean install, on any drive that contains a partition that was compressed using the W9x compression tool, setup assumes that any Windows 2000 install would be invalid.

Windows 2000 does not support W9x compression.

You must remove all such compression from all partitions, prior to installing Windows 2000.
