How to recreate EFI partition completely and install lubuntu 18.04 32 bit


I would like to install lubuntu 18.04 32 bit on a thomson hero9 1bk32 detachable keyboard tablet computer.
Originally, I had windows 10. It was impossible for me to update, and I had bugs, slowdowns etc …
So, I did some housework. I fired windaube using Gparted from an external usb stick.
I formatted the 32 GB emcc disk (soda disk) in NTFS partition. Only, I `` cleaned ‘’ a little too much, because I fired the EFI partition by mistake. Suddenly, I no longer boot on USB key (to install Lubuntu, bootable from refusal or etcher …).
I can just go to the bios.
My thomson tablet has an SD card slot. Suddenly, I thought it was possible to redo an EFI partition and other NTFS partition to use it as a hard drive, using a 128 GB sd card (4 times larger).
I don’t know what to do anymore and how to recreate an EFI partition and install lubuntu 18.04 32 bits.
I have a message at startup “no bootable device. Hit any key”
I have an Insyde h20 rev5.0 bios

What detailed solutions do you have to offer me, please?
I’m only available on weekends, so don’t worry if I don’t get back to you right away.

Characteristics of my tablet computer:
1go welded ram type ddr3
welded hard drive type emc 32go
atom z3735g processor (64-bit compatible)
1 port USB
1 port support card SD

Thank you in advance for your help
See you soon

Can you boot off the USB port or SD port?

Toc-toc, there is someone ?
Can someone help me please ?

The 32-bit version of Ubuntu is not UEFI-ready (out of the box). I recommend you to use Lubuntu 20.04 (64-bit).

And the live-system has its own /efi directory, where the bootloader is located to boot the live system. When you install the system in UEFI mode, the installer will create an EFI system partition or show a warning.


Despite the activation of the uefi and the verification of the iso lubuntu 64 bit image file, I still cannot boot on my usb key using various applications: refusal, etcher, Lili creator made from another computer.
I still get the message “no bootable service”. I can only browse the bios.
do you have a radical solution to bring me please?
