# Warning

This procedure is tricky and may not be recommended to all users. Do

everything at you own risk.

Following this method removes all existing software especially the installed

Android version. If you need Android you may want to follow an other way to

install windows.

The installed windows product number is a fake one and is not valid for new

installations. So you need a valid one.

# Backup your data

First of all you need to backup all existing data in case of something goes

wrong. For that you need to create a bootable Linux USB stick. I use a

64-bit Ubuntu 14.04 LTS(http :// www .ubuntu.com/download/desktop) and

unetbootin (https :// unetbootin.github.io/).

since the InsydeH2O is a 32-bit bios the usb key won't boot unless you put

the

bootia32.efi (https :// drive.google.com/file/d/0B56Bn2CVqCWFMkRmQnZsUUE2dlE/view )

file in the `/EFI/BOOT` directory of the USB stick.

See http :// askubuntu.com/questions/551320/ubuntu-on-asus-x205ta

http :// askubuntu.com/questions/684041/ubuntu-debian-on-a-lenovo-ideapad-100s-linux-has-issues-with-this-laptop

Once the Linux is up and running you can backup the MMC using following:

dd if=/dev/mmcblk0 of=/path/to/usb/mmcblk0-orig.img

This should take about 40 minutes.

# Create an installation media

# Install Windows

## Initial installation

Use the standard way.

## Update windows

Once windows is installed, only the WIFI device is recognized and works

correctly.

You can start to update Windows in the *Setting* *Windows update* menu. Your

tablet will reboot to finish the update. Don't do anything else until this

task is totally done.

During the windows update some unknown devices get discovered. Good point.

Reboot the tablet to finish the update and be patient.

After the reboot you can notice that some divers failed the

installation. Never mind you still can installed them later.

Now is a good time to create a restore point. 10% of available space

(about 2.8Gb) is is a good value.

## Install drivers

Drivers found in the

MRD7-Win10-PVC-WW29.5 (http :// chinagadgetsreviews.blogspot.fr/2015/08/download-windows-81-windows-10-drivers.html)

work fine. Be sure to download the Windows 10 version of the drivers.

### PCI Encryption/Decryption Controller

Hardware ID: `PCI\VEN_8086&DEV_0F18&SUBSYS_72708086&REV_0F`

You can download the driver from intel site (https :// downloadcenter.intel.com/download/25236/Intel-TXE-Intel-Trusted-Execution-Engine-driver-for-DE3815TYKHE-DN2820FYKH)

You need to prive path to `Installer/x86/TXEI.inf` file.

### Intel(R) Atom(TM) Processor I2C Controller

Hardware ID: `PCI\VEN_8086&DEV_0F41&REV_0007`

I got real doubts about the `REV_0007` here. But the online search drivers

works fine.

Once the *I2C* driver is installed some new unknown devices are available.

Now the thing gets nasty. The tablet won't shutdown properly (you need to

shut it down using the a long push on the power button) and won't boot up

any more (the spinning wheel keeps turning on).

Now reboot your tablet in *safe mode* to install the other drivers.
