XP should be installed on C:\ whereas it appears that it is trying to install to J:\ Have you formatted the hard disk or is this a repair? Be aware that if you format, you will lose all info stored on the partition. Is the CD a Windows XP cd or is it a restore CD from the manufacturer of the laptop?
Have tried cleaning the lens, but no luck. Have not installed any new memory
Am trying to install on the C drive and have no idea where J is coming from.
Have formatted the HDD, but backed all my files beforehand.
It is a CD supplied by the laptop manufacturer - Medion - and it says that it is an 'Operating System Installation CD - Windows XP Home Edition Sp1A' However, it is not a hologram CD like a Microsoft version, but I do have the product key.
I suspect that J:\ is either your DVD drive or a temporary drive set up during the installation process. Either way, its the drive its reading from - not reading to - so this is a red herring. However, it may indicate that the install CD is faulty. Have you tried contacting Medion click here. I see that you only have SP1a on your CD - any replacement will almost certianly have SP2. However, if you can borrow an install disc form a friend, try using this instead, but use your own product code.
