Hi, I installed XP on a machine,(C driver) then,
I tried to install 2000 Server over XP. The XP did not allow to install NT
Server, as it is an older version. So I have to install NT directely from
start on the NT CD. The NT installation (on driver D) was successful, but
when I chose boot XP, I got the following error:

Windows 2000 could not start because the following file is missing or
corrupt:

\Windows\System32\Config\SYSTEMd

Start options for Windows 2000, press F8

I tried to install XP over NT,  however, the XP is on a mamufacture recover
CD, to install XP, it must format C driver. After recovered XP, I cannot
start NT.

What can I do? pls help!
