In general you would install 64bit amd64 to modern 64bit
architecture/machine - it might be intel or amd.
If you want to run 32bit on 64bit you would enable multi-arch and install
32bit dependencies.

The advantage is that you would use 100% of the hardware capability and
still 32bit would run, so pick up simply the amd64 iso.

I use "cat /proc/cpuinfo | grep 'model name'", to find the model name 
and look it up on Wikipedia or Google for the manufacturer data sheet. 
64-bit support is often called "AMD64", or "x86-64" by non-AMD 
manufacturers.

If the "flags" section contains "lm", your CPU has 64-bit support, but 
might be IA64 (Itanium, Intel's 64-bit server architecture) rather than 
AMD64 (which Intel itself now uses). I find it easier to Google for the 
model as described above.

Most consumer desktop CPUs manufactured in the last five years have 
amd64 support, including, as far as I know, all Intel Core 2 Intel 
processors (since 2006), even the budget models with Pentium or Celeron 
branding. Some Atom CPUs support 64-bit, but not the earliest models.

Kind regards,

I found it easy:

 # aptitude install lshw
 $ lshw -c cpu

and look at `width'.

Cheers,

Rodolfo

I would just install Windows 10 in a virtual machine like VirtualBox
with Debian as the host. No need for dual booting.  Although you may
have to contact Microsoft directly to get W10 authenicated.  You'll
need sufficient RAM, too.
