I have an Acer Iconia W4-820 Tablet which has an Intel Atom Z3740 64-bit CPU, but the Windows version installed on it is 32-bit.
But it seems the 64-bit USB isn't able to boot. Only 32-bit boots.
I tried to copy the 64-bit setup files on a 32-bit Recovery Disk created from within the 32-bit Windows, but it showed an error that this application isn't supported because my CPU is 32 bit, which is not true as stated above.
My question is how is the 32 bit Window that's installed causing issues with boot media that's 64 bit to not let it boot from it? AFAIK what happens during the boot should be out of reach of the version of Windows that is installed.
