Error Code 0x80070570 - How to re-install Win 10 after deleting Win 7

ljansen · 24 Jan 2018

Hey guys,

I'm new to Windows and have just built my first gaming PC ever. Tried installing Win 10 Home from a USB and got the Error 0x80070570.

Then, I installed Win 7 but now neither mouse or keyboard work. As I type this thread, I'm following the video below on how to create another bootable USB. However, I'm wondering now how to delete Win 7 before I try to install Win 10 over again.

Thank you very much for any help in advance,

- e.g. steps 12,13 deal with existing partitions.

It's a routine part of Windows installation to deal with that.

Try following all the instructions there carefully.

You could even create a bootable disk e.g. Kyhi's with utilities on it, from the top of the Software and Apps section here, boot your PC from it and use one of the utilities to erase your disk if you wished, and you'd then also have a useful tool.

Note that with a new PC, EFI with GPT disk format is preferred, rather than legacy BIOS. (See the tutorial).
