[Starting Windows 7 Setup from Windows Pe 1.6]

In our company we are using the old Windows PE for running an unattended XP installation and I thought I coud install Windows 7 the same way.

But it doesn't seem to be possible.

[Starting Windows 7 Setup from Windows Pe 1.6]

Hi,

I'm trying to install Windows 7 from Windows PE 1.6 / 2005 (which is based on the Windows XP SP3 setup files).

When I start the Windows 7 installation with setup.exe, I get an error which says:

Windows installation cannot be started from the current operating system. To install Windows, boot from the Installation media, or upgrade to Windows XP SP2 or later and restart the installation.

I've created the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Windows

Key and set CSDVersion to 300, but this didn't work.

Where does setup.exe search for the Windows version information?

Thanks
