On a Chuwi Hi12 dualboot tablet Z8300), loaded on Windows 10, I reduced the partition "Windows", by telling me that it was the first stage to pass place of Windows (that I use little) to Android (which misses it).
I used easeUS. The manipulation was made well, in the sense that Windows always works and when I have well a free place on the memory.
Other partitions, EXT3, are always there, and nothing strange under Windows. But I cannot any more booter on Android: logo Chuwi one moment then black screen.
I can switch off and reload Windows.
It seems that the table of the partitions or one of the partitions which interest Android was modified.
Therefore I return to initial size of partition "Windows". But same problem.
Attempt to reinstall Android only (Windows current state). Using ROM proposed by this post (cht_cr...) (http: // forum.chuwi.com / forum.php typeid%26typeid%3D6). With Phone flash Tool Intel with flash-no-erase.json, config Recover).
Many failures (fragility driver USB? Reinstalled). At the end and at best: failure repeated on the installation of the bootloader, with message on the tablet " Failed to get partition bootloader2: Not found ". Rather clear but disappointing: the partition is not recreated ?
Gparted lists partitions but I don't understand role of each. What do ? Modify the table of the partitions by GParted ? Complete reinstall Android+Windows, with flash.json ? But I would want to control the distribution between both OS, and thus to know how to obtain a gpt.bin according to my wishes.
Generally, know what is made by the flash.
Sorry for my poor english.
Thank you for your help.
