Try this little trick.... Install ultra iso place the disc in the drive and make an iso (image) of the installation cd/dvd, then burn that image to a dvdrw with nero, ultra iso, or whatever and try reinstalling. This technique allows u 2 recover information stored in a bad sector on the disc or a moderately scrached disc. HINT: For all u music buffs that scrached ur cd up, this method can be used to recover ur favorite song from a cd most of time without the distortion u here when listening to the same music on the same scratched disc. OH.... Good Luck.
