How to know if windows is installed in EFI mode or not?

I've just got new laptop with Intel Atom N2800 on the board (wiki says
that it is 64 bit) from shop with preinstalled Windows 7 starter 32 bit,
and I want to install ubuntu 12.04 32 bit (exactly 32 becouse it will
couse much less amount of troubles in usage, AFAIK) in dual boot, so from
ubuntu mans I know that
if the other systems (Windows Vista/7/8, GNU/Linux...) of your computer
are installed in EFI mode, then you must install Ubuntu in EFI mode too.
and from the same man page:
To install Ubuntu in EFI mode:
Use a 64bit disk of Ubuntu (32bit installer does not detect EFI)
So, after all of that:
How to know in which mode windows is installed?
If it is in EFI - could I install ubuntu 32 bit with just BIOS?
If it is yes again - how can I do that?
I have already spent the whole day trying to do that, until I noticed that
my laptop has that UEFI and started to google what is that and how to deal
with it.
