UEFI 32 bits

[clearseven]

Hi,
I have an x86 tablet with a 64-bit processor (Z3735F). it has windows 10 32 bit installed on it.
It can boot 64-bit Linux without problem (USB Ventoy or Rufus).
But impossible to boot windows x64 because the bios has UEFI only ia32 (no legacy or SCM).
SO: CPU x64bits but bios in UEFI ia32 bios !!
How to config Ventoy to boot a windows x64? is it even possible ?
Thank you all for your responses.

Try using clover bootloader

No. You need to boot and install 32-bit Windows (or possibly legacy boot 64-bit windows in CSM mode if your BIOS allows it).

Thank you for your response.
For now, I have installed:
    - Windows 10 x86 and - Fedora 39 in X64
both work well.
But since I need to use a 64-bit application, I would have liked to install win x64.
Could you tell me why you think clover or another bootloader won't work?
Just to know.
thanks again.

PS: the Bios have no CSM, it is UEFI only.

If you had CSM, you might be able to load clover EFI64 and then load Windows UEFI64 (I dont know if it works).
But as you only have UEFI32 you would have to load the Clover UEFI32 boot loader which AFAIK will only boot UEFI32 EFI files.
I am not an expert on this, but that would be my guess...

Thanks for the explanation.
I continue to use a dual boot: -win10-x86 / Fedora39-x64

For those who have this Acer switch SW5-012, the touch screen, wifi, bluetooth, ...everything works out-of-box with Fedora ;-)

Have a nice day.
