I recently bought a used xps 420 which didn't come with any of the Dell disks. At that time the machine was running Vista just fine but I thought I want to do a clean install using my own version of Vista enterprise. So I put in the Vista dvd and started the machine. During the install I decided to delete and format the existing HD :eek:. Now I see in the selection window for "where to install windows": Name: Disk 0 Partition 1 Total Size: 111.8GB Free Space: 106.9GB Type: Primary However, if I want to select it I get following error message: "Windows is unable to find a system volume that meets its criteria for installation". I read online that it might be related to the SATA drives but I'm not sure. I downloaded the Intel Chipset Software Installation Utility from Dell but don't know how to run it within setup. I'm also afraid that by just trying different things which I don't understand I might make the problem worse. Thanks for your help.
