    I have a Lenovo Ideapad 100s with a Intel Z3735f
    The CPU is 64bit but the bios is 32bit is it possible to boot Windows 11?
    The laptop suports TPM and secure=boot too

    I see no reason (or any reason) why you shouldn't get it, except that you should still wait until Windows 11 is released.
    I don't want to recommend the current version to anyone, it is not for working purposes to use, it's the first release for developers, it's really too raw.
    PS. Personally I installed it into 16+ years old laptop and it works, but as I already said, it's not usable for working purposes.

    You can test it and report back the results here?

    When needed run these fixes and retry.

    Does you machine has at least 2GB of RAM? Most of the Z3735 machines either have 1GB (HP Stream tablets for example) or 2GB. 32bit Windows 10 already struggles on those machines due to the lack of RAM.

    Since 32bit EFI can't load 64bit binaries (winload.efi), so afaik it won't boot.

    64bit Windows requires 64Bit UEFI. And I think some important drivers for this SOC aren't available in 64bit.

    Just curious, what year was that Lenovo released?
    Odd that it has TPM, secureboot, 64bit CPU, but a Motherboard with support only for 32bit

    UEFI itself is 32bit... lots of cheap atom based tablets/laptops have this issue(?). Windows only boots if the firmware bitness is the same as the OS, Linux loaders have a workaround.

    But the HMM says it is possible to enable legacy mode.

    ps, can you run the QT from here https://forums.mydigitallife.net/threads/multi-oem-retail-project-mrp-mk3.71555/#post-1283849 and post the NOT private report here, in code tags?

    It's because they had developed 32 bit drivers, but not 64 bit ones. So rather than to have to deal with costumers complaining, they ensured costumers would only run 32 bit Windows with a 32 bit UEFI system.
    This way they didn't have to add more than 1-2GB of RAM. And they could cheap out in other areas as well.
    Which means greater profit for the producers of these "PCs". A hassle and PITA for advanced users.

    I think is worth to test the installation booting the machine with Clover or Duet, they are tools mainly used to install MacOS on unsupported machines, but they came handy also for the good guys, in situations where the UEFI bios is buggy, lacks features, or is not there.

    For example to install Windows on otherwise unbootable NVME disks. Or to boot GUID disks on old BIOS only machines.

    Am I the only one that keep having buggy experience with linux
    I have installed Lubuntu numerous of times: Less than 2 hours battery life,buggy animatons and freezes,the laptop motherboard gets so hot even on idle (laptop is passivly cooled).
    Well I know I have to get a new one but 500euro for a 3rd gen Ryzen laptop when 5000 series is out isnt worth it at all.
    I have a desktop but this laptop is perfect for online classes and when traveling
    Im curently using LTSB 2016 with updates and animations turned off
    I also LOVE that it has no fan and the 10ish hours of battery life even after 4 years of use

    Perhaps you can try and use grub2 in uefi mode to chainload the 64bit binary.
