Ive got the same issue on a machine that has no problems whatsoever. she currently runs XP and vista on twin hard drives and im attempting to overwrite the vista drive with the identical .iso file, ive burned 2 dvds so far at max speed (dvds are standard DVD-R quality, not knock offs/rewriteables etc) ill try one at a lower speed and report back in, hopefully that works. also for those of you more savvy in microsoft error reporting gibberish this is the error produced by my tower when it installs. "Windows cannot copy files required for installation. The files may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070017" This is the only thing holding me back from giving windows 7 a test and making full use of my shiny comp that ive got >.< Any further insight would be swell (the problem isnt hardware or any other things wrong, i run both vista x32 and XP x64 on this tower at present and ran the x32 windows 7 beta last year for a while on the same tower, this is a file image problem)
