The Dell is a Vostro 200 (or is it an Optiplex 330?) desktop. I'm miles / km from it and won't see it again until mid-week.
Thanks for the comments.
The Win7 I'm trying to install is from a disk directly from Microsoft via Techsoup. I've more-or-less switched to Linux myself, but the computer in question is for an employee who needs to be MS compatible without question and is barely computer literate.
