I have spent a week trying to do a clean install of Win7 RC on a newly rebuilt computer - but no success. System is Asus P5KPL-AM/PS MB (new), Asus EN8400GS PCI-E vid (new), 2GB Kingston DDR2-800 RAM (new), and an Intel P4-3.4 CPU (used but working). I first tried a clean install on a reformatted 30GB partition in a 120GB Samsung HD using both a newly burned DVD from a M/S .ISO file and a PC Authority DVD, with exactly the same result. The install seemed to progress normally with no reported errors through "Collecting Information", "Installing Windows/Copying Windows Files, Expanding Windows files, Installing Features and Installing Updates", but at the first re-boot it got as far as "Press any key to boot from CD or DVD...." - then stalled. Pressing any key within 5 secs of the message made it boot from the DVD. On re-booting without the DVD in the drive it would stall after the POST at a blank page with a flashing cursor. It made no difference whether I installed over the previous install, or reformatted the partition first. Someone suggested that 30 GB was not big enough to install Win7, so I tried on a new WD 320GB HD, both clean and formatted, but no change. To check the hardware I installed XP Home on the original 30GB partition, and it installed and ran perfectly - including several re-boots. No other install problems in this Forum seem to equate to this. Can someone help, please?
