[Windows 8 General] sbasil:
1) Clean Windows 8.1/10 Installation from your own installation media (ISO)

X80H FB5M Windows installation (Remove Android and clean install Windows using an ISO image)

I)	Write down your current Windows Product key first!!! You need it to activate Windows later on. To see your Product Key, you can use NirSoft’s ProductKey (http://goo.gl/1tnqY) or some other equivalent.

II)	This is how I “clean” installed Windows on my X80h. If you manage to mess up your tablet using this guide, you’re on your own. That being said, it's not rocket science!

III)	I downloaded Windows 8.1 with Bing ISO image (32bit) using torrent (in case someone is wondering how to get it). You could also install Windows 8.1 pro as well if you so desire. However, the Bing serial won’t activate Pro version. Also, I noticed that Bing was somewhat faster on X80h than the Pro version.

IV) Install and activate Office 365 on your current Windows before wiping your SSD drive clean (if you haven't already...just to make sure that you won't lose your one-year-subscription to Office 365 and 1TB OneDrive space).

Make a bootable USB installation media manually or use X80H Toolbox for Windows (the easy way)

1.	Open command promt and type diskpart

2.	list disk

3.	select disk X: (X being your USB drive,

make sure you choose the right one or you could end up deleting wrong disk

)

4.	clean

5.	convert gpt

6.	create partition primary

7.	select partition 1

8.	format fs=fat32 quick label=”WIN8”

9.	exit

10.	Copy Windows installation files to your USB stick (all content from your ISO image)

Windows Installation

1.	Charge your battery at least up to 60-70%

2.	Connect your USB installation media and an external keyboard to your tablet

3.	Power on the tablet and tap “DEL” key for your tablet to enter BIOS

4.	Go to “save and exit menu” and select your USB drive as the boot media (it’s under "boot override")

5.	Delete all the current (Windows & Android) partitions and let the setup create new ones (Recovery, System, MSR & Primary)

6.	Install Windows & Drivers

7.	Use your own product key to activate Windows

Drivers

You can get the Windows (32bit) drivers from the link provided in the first post [MENTION=243864]xda[/MENTION] (http://goo.gl/UzVXmu) **thanks to xxLeoxx93*

The best and quickest way (for me anyway) to install all drivers is to extract them to one folder and then install them from device manager (unknown device  browse my computer for driver software  Browse for driver software on your computer  select your “driver folder” and click next. Windows will automatically recognize and install the right driver for the device. Do the same thing for every unknown device).

I had some problems with the screen after Windows was up and running (the orientation was mirrored, but the reg file attachment should correct it (works OK for me). Or if you want to do it manually, open Regedit and browse to

“[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ROOT\SENSOR\0000\Device Parameters\kxfusion]”

And change the values to

"Orientation"=hex:01,00,00,01,01,00,02”

If the screen won't rotate, try installing drivers from x98's forum (with the registry values given above). Here's the link for the drivers

Worth mentioning

After you've installed all updates and such, run disk cleanup as an admin in order to get more free space (at least a couple of gigs or more).

How to re-install Android?

Don't know, don't care... :eek: But if someone knows how to install Android on an SD card, that would be...interesting.

Edit: Use these instructions (F4BM) in order to re-install Android, just start from the #3 (skip flashing the bios). And don't forget to thank jazk . Updating Android seems to break Windows boot menu (someone already mentioned it), so beware! Using smaller customized partition sizes (4GB for instance) still takes over 7 gigs of disk space (4+2+1+several smaller partitions).

2) Windows 8.1 with Bing installation from Teclast's official WIM-images

How to install Windows 8.1 with Bing using WINPE and Teclast's original Windows image on FB5M.

(I felt like tinkering, so here goes nothing again...I'm not sure if someone has already written the same instructions, probably, but...Repetitio mater studiorum est!

I still prefer creating my own ISO W8BING media with all updates and drivers pre-installed (**), but this is one way to do it. )

Prerequisites:

1)	2 USB Sticks (1x > 256MB & 1x >=8GB)

2)	Battery charged to over 60% (preferably to 100%)

3)	USB HUB with at least 2 USB ports, preferably 4

4)	WINPE and Windows 8.1 installation files. You can get them HERE

Notice: Following this guide WILL wipe your tablet's SSD clean and install Windows only!

1)	HOW TO PREPARE THE USB STICKS:

WINDOWS PE BOOT DISK

-	open command promt

-	type “diskpart”

-	type “list disk”

-	select your USB drive by typing “select disk X” (X being your USB drive)

-	type “clean”

-	type “convert gpt”

-	type “create partition primary”

-	type “select partition 1”

-	type “format fs=fat32 quick label=”WINPE”

-	type exit

-	Download Tools.rar

-	Extract all files from the WINPE folder to the root of the WINPE USB stick

-	Go to “SCRIPTS” folder and edit Main.cmd file with Notepad++ or equivalent

Find the following lines

“@echo call diskpart /s %InstallPath%\wimpart_dual.txt

diskpart /s %InstallPath%\wimpart_dual.txt”

and change them to

@echo call diskpart /s %InstallPath%\wimpart.txt

diskpart /s %InstallPath%\wimpart.txt

Save and exit

WINDOWS 8.1 WITH BING INSTALLATION DISK

-	Format the 2nd USB stick (NTFS)

-	Download Windows 8.1 with Bing files from the link provided by xxLeoxx93 [Windows 8-1.part1 - Windows 8-1.part5]

-	Extract the RAR and copy “images” directory to your NTFS USB stick (yes, the whole directory, not just the files inside it).

INSTALLING WINDOWS

1)	Connect a keyboard and both USB sticks to your USB hub

2)	Power on your tablet and press “DEL” in order to open the BIOS menu

3)	Boot your tablet from the WINPE drive. If everything goes well, Windows installation should start shortly after (the installation process is automated  sit back and relax). That’s it!
