I lost my windows XP SP1 original CD. However, I've saved the whole cd in my external Hard Drive before, as a habit from win 98. My local HD crashed yesterday. I burned the Win XP files in my external hd to a CD and tried to start it but it never succeeded to read it. However if I insert it in another computer, I can see the files. Maybe my cd rom has crashed too. I tried to copy all the files to my local hd using another computer, too, but the installation didn't start from local HD either. And I don't have flopy drive. Any suggestion how to install XP from local or usb hard drive without flopy disk drive?
