Can you use an upgrade disc to create an unattended install of Windows 7? I have an upgrade disc of Windows 7 Pro x64. I know there are methods to do a clean install from the upgrade disc. My ultimate goal is to copy the unattended install to my 8GB XT flash drive and use that. Has anyone here used an upgrade disc for this? Or is everyone using the full install disc?

Thanks

my upgrade disk I got from Dell some time ago was identical to a full install disk except the ei.cfg file in sources. just delete it

I tried deleting that file and it didn't seem to change anything. It's still saying it won't install on this disc w/o a previous version of Windows. Any other ideas?

Thanks

Then perhaps you do have a true upgrade disk. Was it from an OEM like dell, hp

No, it wasn't from an OEM. This is the one I bought: http://www.amazon.com/gp/product/B002DHGM50/ref=pd_lpo_k2_dp_sr_1?pf_rd_p=486539851&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B002JYU5WI&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=14J75PDCAPNN4M5H9Q41

oops that is only 1 version in that Pro so no need to delete the ei.cfg. paste what it has in that file
