Windows USER`S PLEASE READ THIS! we need your help

[joao1979]

Hello, first of all please do apologize for my English (i´m portuguese) , and an actual yogabook android version user.
We (the android users ) are having some hard times trying to boot windows on our tablet (it makes sense because it´s the same machine) therefore, what we need right now, is for someone who could acess his bios (there´s a thread here explainning the process, its actually quite simple) and, tell us how the windows bios is configurated, to allow us do a "copy/paste" of the configuration.

would you guys be so kind and help us out? :crying:

I think its a very different bios on the windows version. Probably accessible upon keypress on boot but very different from android one.

i really hope you´re wrong lol let´s wait and see if anyone could help us out with this, because i can´t belive tha same hardware can only boot one OS

Dont think it's accessible on Keypress. That hasn't been a thing since Win7, I believe. Exactly what settings are you looking for? I could probably just share some pictures of mine, if thats easier.

thank you for the reply, what we need is to see wich are the options on windows bios that are enabled, to try to boot a windows on our tablet, i belive if you try accessing the bios trough the steps that are on this forum it´s the easiest way. would you be so kind and show us how your bios is ?

 

[sawyerbenjamin]

Hopefully that shows up.

Many thanks !
I just checked with mine, the bios is just completely different !
Do you have an option with ACPI enabled or disabled ?
That's what most of android users have after booting windows 10 on usb key.

ACPI is branded in the bios and on by default as Windows has it under control.
Power, Device, Processor-States etc... all handled by Windows and not like older (very old) bios which had APM
That's why you need another bios if you ever want to dualboot.

I'm pretty sure you can download the BIOS from Lenovo. I couldnt help you install it from Android though. Seems like a very easy way to a bricked device.

Well... There is a tool from lenovo site, but it seems to update only if you already have windows 10 (exe file).
Vicious circle !

You got it. Quite easy to brick it.

I am pretty sure Lenovo burned the BIOS in an EEPROM. Differently between Windows and Android models. Updates are just flashed in a CMOS, well rather NVRAM nowdays. That's why Windows and Android models have completely different approaches when it comes to update the BIOS. I doubt there will ever be a way to flash (supposed) "Windows" settings into a "Android" device, as the EEPROM was initially fixed differently, expecting specific store instructions for the NVRAM depending the OS model.
