You can use your Linux live cd running in live mode to pull off data off the old drive. You should do this first before installing the used 80 gig drive you want to install. The live cd will run independent of the installed hardrive and you can pull off your data in windows on that drive to lets say a external uSB drive.
This leads to another question? With the old OS gone (Once I am up and running with Linux I need to go back into my old master drive and remove the data files, which are fine, it just cannot boot into Windows…. the cause of the crash) how does the monitor, mouse, and keyboard work to do this?
