New installation Not working

Installing Parallels 11 and Windows 10 on a
iMac (Retina 5K, 27-inch, Late 2014) with Fusion Drive and running El Capitan
results in alternating Wizard screens ( Windows and PC Problem )

 

Hello UrbainE,
Please let us know how you're trying to install Windows 10. Are you trying to install Windows 10 using a USB stick or using an ISO file?

 

I am using an ISO file

 

Hello UrbainE,
Please download a new ISO file from Microsoft website and then try to install Windows 10 and let us know how it works!

 

After Downloaded two times Win10_1511_1_EnglishInternational_x64.iso , the installation gets a little bit further. This time the installation ends (several times) with:
"The installation was cancelled.

Any changes made to your computer won't be saved

Windows cannot install required files. The files may be corrupt missing. Make sure that all files required for installation are available and restart the installation. Error Code 0x80070570"

 

PS I also downloaded ParallelsDesktop-11.2.0-32581.dmg again...

 

Hello UrbainE,
Did you purchased Windows 10 from Microsoft online store or is it purchased from Dreamspark? Please let us know the size of the ISO file which you have downloaded.
Please uncheck "Express installation" & install windows 10 and check how it works.

 

The Windows 10 was purchased from Microsoft online, the size of the iso image file is 4,393,349,120 bytes,
Unchecking "Express Installation" leads to exactly te same result.

 

Hi UrbainE,
Please check your private message and reply back to that.

 

Hi I got exact same problem as you, on my MBPR 15", with PD11 & WIN10, did you get any good solution?
Did you use EFI guide to install Win 10?
Thanks

 

Hello scyang,
Try to uncheck the Express Installation on step 4 and check how it works.

 

Hi Pradeep,
I tried your suggestion but still doesn't work, the Chinese service center give another suggestion is downloading iso file from Microsoft, and use it for installation, then everything solved, I suggest everyone who bought Win10 OS USB pack, try to download iso instead of using that USB in Win10 software box.

 

Hello scyang,
There is a different installation process when you are trying to install Windows 10 using USB.
Plz refer to this article.
