Our tablets are based on Intel SoC, so we are ablet to run Desktop Os, like Windows 10 but also like GNU/Linux Distros.
The main problem is UEFI on Baytrail tablets (Teclast x98 Air 3G, Air II, Air III), because they use a 32 Bit UEFI, that is really different from classic UEFI (64 Bit, like Teclast x98 PRO and other Teclast running Windows 10 x64).
But, Linux users and Linux developers are really smart and they provide a compatibility patch to boot 64 bit operating system on a 32 Bit UEFI running on a x64 Tablets (yes, it is not a joke).
Remember, you can always turn back to original Teclast Duao OS configuration using my guide:
- [GUIDE] Teclast x98 Air 3G: fresh install Windows 10 and Android with repartitioning
Now, what you need:
- A compatible x64 GNU/Linux distro: please start with XJUbunTAB
- Rufus to burn the Distro on a Pendrive
- Additional bootia32.efi to put in Pendrive/EFI/Boot
- HUB USB with a Keyboard and Mouse
Procedure:
1) Burn your ISO on a Pendrive and check if "bootia32.efi" is placed in efi/boot on the Pendrive burned;
2) Plug your HUB with pendrive, keyboard and mouse;
3) Turn on your Teclast by pressing 2 seconds power button and start press ESC on Keyboard;
4) Go to the last tab, find Boot Override option and select your pendrive
5) Start installing Xubuntu, the first time is better to erase all partitions except EFI; Set bootloader on root of hard drive (eMMC) and not on the partition you will create to install Xubuntu..See the following image, I've partitioned my Teclast x98 Air 3G using gParted Live:
6) Finish installation and power off the tablet;
7) Restart your Teclast tablet with the same config (HUB with Xubuntu pendrive..), enter in Bios and select Boot override..In the Grub option, press "C"
8) Now you have to find the name of disk and partition where is installed Xubuntu, in my case it was "hd1,gpt2"..So write:
#ls
Now try to see folders in each partitions, so digit (x means a number..):
#ls (hdx,gptx)/
If you see a file called autorun.inf or a folder called casper/ its would be the USB stick, so try another partition. If you see a file called vmlinuz and one called ignited.img you found the correct pairtion.
8) After you have checked the correct Ubuntu partition, write:
#linux (hd1,gpt2)/vmlinuz root=/dev/mmcblk0p2
#initrd (hd1,gpt2)/initrd.img
#boot
9) Nice, you are now booted on your Xubuntu installed OS, now please remove the pendrive;
10) Download grub-efi-ia32 and install it!
11) Restart tablet, now you are able to boot without point "8" of this guide!
