Does WIndows 10 Support 32 Bit UEFI Mode ?

  • 0

During my work I have previously successfully deployed PC’s with several Computers with UEFI Booting with GPT partitioning for a while now – due to its advantages ( I understand UEFI supports 2TB+ drives and is quicker to boot ) , this UEFI booting was also influenced by being supplied with more modern motherboards which do not natively recognise MBR partitions

It seems the general concensous is that UEFI is a technology that only supports x64 Operating systems , is this correct?

We are being suplied with Netbooks which have 32GB SSD’s and I would rather install X32/86 Windows to save a Few GB . I have created a Dual X32/x64 Win 10 Image with UEFI boot and GPT partitioning , however this throws an EFI error when I run the 32 bit install but runs fine on X64 ( Using Rufus )

I also tried creating and running a MBR with CSM for UEFI but Windows does not recognise the SSD

I spoke to ASUS , they rekon their netbooks support 32Bit UEFI Win 10 OS , so am a bit lost

This is an Asus E402MA-WX0055T

    64-bit requires double the memory as well.
