I'm having problems installing Windows 7 on my new PC. I just build the computer using these parts... Not sure if that matters, but there it is. I have set up the two 500GB HDDs in a RAID-0 (the install can see the drive, so I do not think that is the problem). I purchased an upgrade version on Windows 7 Professional 64 bit through a cheaper-than-dirt college program (only $30. And yes, it is legitimate.) This gave me an ISO image which I burned to a DVD. I am trying to do a clean install of Windows 7 as the first and only OS on my new system. For whatever reason, when I try to do the install, I get a 80070570 error and the install fails (at around 5% into the "Expanding WindowsFiles" stage). I assumed, with the aid of some other forum topics, that this was likely due to a bad DVD burn... so I made a bootable Flash drive and tried that... same thing. Does anyone know what is causing this or a possible solution to the problem?
