Just so you know you won't even be able to boot a 64 bit bootable drive if your cpu is 32bit. Tried before and know from experience, at most you'll just get an error message and crash.

A high quality power brick can deal with spikes like that, but it'd be a good idea to get a higher wattage power brick. 

msi has been doing stupid hybrid power since forever. if your power draw exceeds how much ur adapter can draw, it'll drain battery as well. When you hit 0% battery while plugged in all your components will start massively throttling to keep the computer on. there's no harm but it's just a dumb design. It existed with the GT80s as well.
 
Check if the newer GE series have a higher rated adapter with the same connector, they normally keep these things consistent. Aim for the 230w ones since your power draw is at 200w or so. 

Ok Windows 10 can only be installed on a gpt partition ( as far as know) so you can try following this guide https://technet.microsoft.com/en-us/library/dn336946.aspx
to recreate the partition table, if you have a linux live cd you can also use gparted to do this.

Assassin27 said it gave an error saying it required a gpt partition so it's most likely a partition table issue.
Also I've installed windows 10 on my relatively old   TOSHIBA SATELLITE C855D which run on a piece of utter crap known as the amd E-300.
1.3 ghz, dual core, and over 6 years old.
