"Windows could not complete the installation. To install windows on this computer, restart the installation."

On a 64x you need 20gb of available space. Not sure but thats cutting it kind of close.

Did you do as the message suggests and try installing again to see if it worked?

If so, try re-downloading the RC ISO and burn it again in case there was a problem with it.

nope , i istalled it when i had 14 gb of free space . windows just noticed that this is the minimum amount of free space requed for instalation

i got a bunch of dvd-rw disks , have 5 of them with win 7 diff builded burned

try to butn it once again , better use dvd-rw discks at low speed

Try to go for fresh complete installation. Never try to upgrade if you are using Windows XP or Vista other than Vista SP1. Upgrade is advisable only for Vista SP1. PLZ try to read the instruction online before installation from Microsoft. Go to the installation instructions here
