Fran,
I did several installs using the 'copy' CD and there was not one single problem at all !
My PC HDD was re-fomatted many times because of upgrade/downgrade sessions from WIN98 to ME to WIN98 to WINME to WIN98 to WINXP to WIN98 to WIN2k to WIN98 !!
The original B4 disk is stored on a safe place.

I did a 'test-run' on my 2nd PC too..... and it worked as well. ;D
