Selecting OS screen lost

[josep]

Hi, I had to reinstall android and windows (I got windows 10 from microsoft media creation tool) and now I can´t shoose what OS to boot from.

I tried pressing volume+ and power buttons for 10 seconds, but android boot.

May be there was any partition I deleted accidentaly while windows installing? I don´t know how to do now…

I own another Teclast tBook 10 (my wife´s own it) that works fine…Could I recover any file I need from this one?

 

THANKS

Should be there. You must have ticked that box in error to make is disappear. Any holding volume + on boot nothing?

Ok, finally I fixed reinstalling all manufacturer firmware; windows 10 installing following Teclast manual is diferent to microsoft’s media creator, and it seems to create all needed partitions and boot files.

Have you got the M5F8? I have the same problem…

Hello. I have the tbook16power (M5F8) too. I wiped the internal Memory and flashed it new with intel phone flashtool (only Android). Then i booted a windows 10 64bit uefi installation-Stick and installed windows. All works fine. Then i flashed android TWRP-Recovery for teclast tbook 16 power (m5f6?) and it works fine too. then i rooted theandroid and it works two days verry fine with android and windows. but now, the Battery goes empty becouse of forgotten to charge. and after charging, the white Bootmenu was lost. at first, i could switch with “Boot to Windows” or boot to android-Apps, but since today, all switching is lost…

Does anyone knows how to get the Bios or EFI Files? I think, the Bootloader or Bootmenü is stored in the BIOS, or EFI, or at some other places,not in the emmc.
