You can install Windows 10/32 but, Dell only has drivers for Windows 10/64 on this system. You may run into issues with not having the 32 bit drivers.
You may face a big issue - 32-bit Windows 10 won't usually install without Legacy (BIOS) mode (it can, on systems that have support for 32-bit and UEFI, but this one very likely does not).
There's no real reason for 32-bit Windows 10 any longer - so you're better off keeping the 64-bit version.
32-bit Windows 10 won't usually install without Legacy (BIOS) mode (it can, on systems that have support for 32-bit and UEFI, but this one very likely does not).
This is what I'm suspecting. I've tried all variations of BIOS / Legacy / UEFI / Secure Boot settings with a bootable USBs created with Microsoft's Media Creation Tool and Rufus (GPT and MBR).
I can get as far as the screen to select a drive / partition to install, but receive the "Windows cannot be installed to this disk" error.
I guess the Inspiron 11 3162 is simply not compatible with Windows 10 32-bit, even though the system BIOS does have Legacy options. Perhaps the system is compatible, but the eMMC drive is not?
If anyone out there has had success installing 32-bit on the Inspiron 11 3162 / 3164, or has any other suggestions, please let me know.
