Hello @Keruzhko2 

Do you have possibility to disconnect the eMMC SSD drive ?

32 GB eMMC

No. I think I should disattach the display for it. But I am afraid I won't be able to put the parts together accurately after that.

Is there some way to connect the unloaded tablet to PC as an external drive?

Hello @Keruzhko2 

The easiest way would be simply making a bootable USB-stick with Ubuntu on it, then once in Ubuntu, fire up GParted. Just leave the first partition there since it's used by UEFI, but delete the rest.

Please report your results

You are right. That would be quite easy. As well as installing Windows from USB. But I cannot boot from any USB or SD card. This is the main issue indicated in the topic.

Are there any limitations on USB-stick for this product? Perhaps, it can boot only from small-size ones or the ones limited by speed and so on. My current USB-flash is 16 GB in size. SD card is 32 GB. They were perfectly recognized after booting into Linux.

Finally, I've managed to install and launch Windows with the use of the USB card reader. It's strange, but the portable OSs and installers are well read from SD card connected via an external reader but not from USB sticks.
