To successfully install Win 10 onto an Android 7 inch tablet

In our country there are many power failures which obviously affect trading. So I went and bought a tablet to run on batteries in those times. My humble opinion: for me, MT4 on Android is useless. I tried everything I know (which is not much) and everything I could find online to install Win 10 (which I have on a USB stick) on a cheapy 7" Alcatel Tablet running Android Go OS, but nothing will work. I would like it if the 2 OS can reside both in the tablet so I can choose which one to run. There is software which is claimed to be able to do that, but I cannot find the Win 10 part of it and could not get it to work obviously. If it really works is also unclear.
Surely one of you tech savvy traders can help me to to do this?
Thank you in advance.

If in doubt I'd install Ubuntu on the device or install the o.s on a SD card, wine works well enough to install mt4, I haven't mucked around with tablets much but as long as you can access the bootloader you should be fine, you will need to install a few more things for mt4 to work on wine though, fonts amongst a few other things and will involve you researching this yourself x

Thank you, it looks very helpful. I will research all this asap.
Do you perhaps know offhand if indicators available on the market will work on the Ubuntu etc?
