Installation Error 0x80070570 while installing Windows 7

I'm trying to install Windows 7 on my computer and am continuously getting the error code 0x80070570 when installation gets to around 77%.

I have tried using around 7 DVDs of the 64-bit version, all showing the same problem.

Answer

Start the install, let it go to up to 50% or something like that (before it reaches the critical 77%), and then cancel the install. It should take you back to to Install Now screen. Then start the install again. The installation should work now without any errors.

You may also want to disconnect any unnecessary hardware from the system before starting the installation. This includes any USB peripherals, including but not limited to:

• printer


• scanner


• microphone


• external disk drive(s)


• USB flash drive

You basically want to disconnect everything except the keyboard and mouse which is necessary for the installation guide. This may also include:

• video cards


• graphics cards


• network cards


• secondary internal disk drive(s)

Of course, not all of these components may be applicable to a laptop computer. And for a desktop installation you don't want to disconnect the internal disk drive on which you actually want to install Windows on. This is the only disk drive you want to be connected to the system during the installation.
