Hello,
Recently I upgraded my Dell Inspiron 15R with SSD and wanted to install Windows 8.1 pro 64-bit on it. I downloaded the windows from Dreamspark with Secure download manager. I made a bootable USB stick twice withWindows USB/DVD Download tool, booted the windows setup, formatted the ssd and tried to install when i got this error. As I recall the error code was something like this "error 0x80070570". Any advice how to overcome
this problem?
