Hi, I have searched the web and this site hoping for a resoluton to this problem. If I am repeating a problem that someone else has mentioned then I apologise. I have a Dell 9100 Inspiron laptop. It has recently ground almost to a halt so I decided to upgrade my harddrive and install Windows XP home edition. I checked that my Fujitsu 80Gb hardrive is supported by the OS. It is. I then put it in and tried to install XP home using the Dell CD taht came with the laptop. Everything goes well until 13 minutes to go in the installation process (driver signing) where it just hangs, looking for all the world as though it is doing something. I have left the laptop for hours only to see it at the very same position. I have added nothing to the laptop other than the harddrive, which is picked up correctly by the BIOS, and presumably by the Windows installation process in that it correctly copies data to the disk. Has anyone else seen anything like this? I will later on plug my old harddrive back into it and download a BIOS upgrade. See if that helps! Also heard that if you modify any of the defaults settings in the installation process it could cause these problems? Is that true? I am suprised that an installation as basic as this could be so problematic. Thanks in advance for any help or advice.
