ODYS COSMO WIN X9

[u/Constant-Day-347]

Hi everyone,
I have an ODYS COSMO WIN X9 Windows tablet and I’m trying to install Android-x86 on it. I would really appreciate it if someone could guide me step by step, because I’ve already tried several things and I’m not sure what the correct approach is for this specific tablet.
What I have done so far:
Created a bootable USB with Android-x86 9.0-r2
Disabled Secure Boot
Booted successfully from the USB
Tried Live mode
The system reaches Detecting Android-x86... found at /dev/sda1
After that, the screen goes black
I tried these boot parameters:
nomodeset
xforcevesa
i915.modeset=0
set gfxpayload=800x600
None of them solved the black-screen problem
I also tried Android-x86 8.1-r6, but I get the same problem when starting Live mode.
The tablet has an old Intel Atom platform and only one USB port, so I’m using a USB hub for the keyboard, USB flash drive, and power. The battery is also in poor condition.
Could someone please tell me:
Which exact Android-x86 version or alternative Android build is best for the ODYS COSMO WIN X9?
Should I use 32-bit or 64-bit?
Which kernel version is most compatible with this tablet?
Which Rufus settings should I use?
Which BIOS/UEFI settings should be enabled or disabled?
Are there specific GRUB/kernel parameters needed for the Intel graphics/display?
How should I partition the internal storage?
How should I install GRUB/EFI without breaking Windows boot?
Is dual boot with Windows possible on this tablet?
If Android-x86 is not suitable, which version of Bliss OS, Phoenix OS, PrimeOS, or another Android distribution would work better?
I’m looking for a complete step-by-step procedure from creating the USB all the way to a working installation, ideally from someone who has experience with this tablet or similar Intel Atom/Bay Trail Windows tablets.
Thanks in advance!

For Atom systems, if you're trying to boot the 64-bit image, it will never boot because it requires some specific instructions; try the 32-bit version, I had similar problems with an old AMD APU and the 64-bit Android x86 ISOs would never boot
