My Cd-rom Doesn't Work After I Used The Restore Cd

[rik]

If you boot the system into DOS or have the ability to boot to a cd and open a DOS session you should be able to explore the root of the c: drive and you may see a C:\windows directory and a c:\winnt or something close to that...

[EDIT]
what might be easier...if you go to START|RUN MSCONFIG click on the BOOT.INI tab, if there are 2 installs of the OS it should show 2 differing lines under the [operating systems] entry.

BTW, if this is a restore cd why do you think it installed a 2nd copy?
