Hello, I do this : - boot on DVD, no problem - Insert key, no problem - select target partition, no problem - I select "Custom installation" (the only option available) - I select the partition, no problem - I format, no problem But when the installer says "Installing Windows", I have a message : "Install Windows - Insert disc - Please insert Windows installation disc1". What can I do ? The DVD is still in the the DVD player of course ;-) I'm on a DELL Inspiron 8600C - 1.5GbRam and 60Go hard drive. Thanks,
