Cheap Windows Tablets are sometimes great. Specifically, if it comes with Microsoft Signature Edition Windows version as the Windows does not have any junk.
However, cheap often comes with some trade offs. For example, I bought this really cool Nuvision TM800W560L Tablet.
But someday ago I messed it up. I thought of installing a clean Windows and it went horribly. After installing I did not have any sound or touch or battery. I thought this would be a junk and Nuvision Customer Service was one of the worst. The customer care guys do not know a thing about this particular tablet TM800W560L Nuvision Tablet.
Why I had to clean install?
My installation stuck at about 68% while I tried to install an Insider Preview. The tablet wouldn’t turn on. It would just keep restarting in a loop again and again. And nothing seemed to be working. I often got a GSOD but it rebooted so fast, I never could read what’s the error. So I thought of installing a clean Windows.

How to USB Boot Nuvision TM800W560L
The Nuvision customer service representatives are so dumb they don’t even know what is the key to boot. I had to restart countless times to actually find it out which is the key to boot.

4) Micro USB to USB Converter
The Nuvision TM800W560L booting key is F7. You need to turn off the tablet. Click the power switch and immediately start pressing F7. (plug keyboard in USB hub). You’ll see the boot menu popping up.
Nuvision TM800W560L Driver Issue Fix / System Restore
Your Nuvision TM800W560L has no touch? No audio? Messed up? Not Booting? Then you need to restore your Nuvision TM800W560L to factory image. But the problem is, Nuvision Download Center does not provide software for this tablet anymore. Fortunately, I downloaded the System Image and I can provide you that.
After downloading and extracting to a local folder, you’ll get a directory with files like this
But how to make use of these? I’ll show you how.
How to install Drivers/Factory Windows on Nuvision TM800W560L
- First, you need to make sure your USB hub is working and the plugged in keyboard is working. You can try pressing F7 while rebooting to check. If it’s okay then go on to the next step.
- Download the software from above link.
- Extract it in your PC.
- Format your USB to fat32. Copy all the contents that you extracted to your USB. After completing the copying, we have taken all the files to the USB.
- But we still need to make the USB bootable. (We can’t use Rufus because Rufus would have needed an ISO or img).

So, we’ll make it bootable via Command Line Prompt.
- Open cmd.exe with admin privilege
- Navigate to the Extracted folder where you have extracted all the files and navigate to the folder using cd command
- Type cd boot
- Type bootsect.exe /nt60 F: (where F is the letter of our removal/USB disk drive.)
Now here is the tricky part. Boot this USB from your tablet by pressing F7. If you are lucky, your PC will find itself working again. But in my case, the boot script was formatting the USB itself every time. And I was getting an error like this
The USB key was partitioning the USB key itself, whereas it should have been partitioning the internal hard disk of the tablet
Now in this step, I began studying about how this mechanism works. The thing is Microsoft has a different way to install Windows on smaller devices which has less RAM and storage. It’s called Windows PE Deployment.
I knew the boot process was right. All I had to do is to let the system select the internal hard disk not the USB. So I began reading files from the extracted contents. And I finally found the fix.
The Final Trick
You need to go to the Scripts folder in your USB. You’ll see these files. Open the Main.cmd File using any text editor. And you’ll find a line about set disk on line 26.
I knew this line was the culprit because the automatic mechanism wasn’t selecting the required disk. it was selecting disk 1 whereas it should have selected disk 0. I changed it to
The Final Trick 2
If the above workaround did not work for you, there is an easy alternative I found recently. After doing everything just rename the USB Disk as “WINPE” and restart. It should solve the problem!
Saved the file and plugged into USB. Finally, it worked!
Voila! It worked perfectly!
