Intel 8th Gen Boot Windows 10 32-bit

I have a requirement for new Dell 3060 to boot to 32-bit OS for industrial control.

The issue is that the EFI will not boot to 32-bit, and that leaves me stuck.

Is there a way to install a 64-bit Boot Loader (eg GRUB) and have it auto boot to a 32-bit version of Windows 10 …?

If your mobo supports disabling of secure boot mode and has a CSM function it should work with 32 bit.
Normally you can install any 32 bit OS on a 64 bit machine.

Didn’t Dell remove the legacy boot option in newer systems? (i.e. since late 2018)

@GnarZ77 , you can disable secure boot, but not support for Legacy OS anymore on Dell hardware …

@chinobino , yes, Dell have removed the support for Legacy boot - so no more 32-bit - that’s why I was wondering if it is possible to install a 64-bit boot loader (eg GRUB) and boot to a 32-bit Windows 10 partition (problem is that the application in use will not run in 64-bit on any platform (Windows 7, 8 or 10) and the cost of replacing the equipment is astronomical (looking at 200K+ per unit!) They say that they will support Windows 10 64-bit in 2022 …

Anyone any ideas?


try AIOboot it uses grub2

see if it can boot Win10 32bit installer


I can boot from 32-bit installer, and install Win 10 32-bit, but cannot boot once installed …


can you chainload to boot it?…n_UEFI_with_GPT

@infuscomus , not really an option to chainload … I was hoping to have a Dual Boot option, with a 1 second delay in GRUB, but as I cannot get 32-bit Windows 10 to boot on the machine, even when freshly installed, I can’t install it using BCD or any other Windows based tool …


why is chainloading not an option?
