I'm contemplating installing Debian on my beloved Chuwi Hi12 tablet. The machine is cheap (circa $300) and while there are certain bits of the hardware that do not (yet) work under Linux there is nothing that troubles me, and the graphics are superb - 2160x1440 on a 12" screen.
At present it is dual-booting Xubuntu and Windows (Android was removed). I installed Xubuntu because I could not at the time successfully burn a Debian live image to USB, so could not test it out before installing. Now I have a new live Debian USB and have tested it on the Chuwi. Everything works as expected. No wifi (rtl8723bs chip) but that was expected. I'm ready to install debian-live-9.3.0-amd64-xfce from the live USB and would like to install it to the whole of the Chuwi solid state 64gb drive, binning Windows and Xubuntu in the process. But I'm nervous about the possibility of turning the tablet into a brick. It has a 32 bit UEFI system and while I've tried to research the UEFI complications find it difficult to grasp the full picture on UEFI (particularly 32 bit with a 64 bit Debian). As best I can make out I should have no problems as the Debian installer will detect and handle the 32 bit UEFI. However I've been unable to find full instructions for using the whole of the storage for Debian, only guides for dual installs alongside Windows. Does anyone have any comments or suggestions that might be useful to me in the installation? In particular do I need to preserve any existing Windows or EFI partition even though Windows will no longer be on the machine? Any help would be greatly appreciated. Thanks in advance.
