Seeing it is a new Machine. You can make a live USB Using Unetbootin
for Windows and download and install any live distro of Linux from the control panel in Unetbootin. That way you can run a Linux Distro as a Live session off the USB drive and see which works best with your Emachine Laptop. That is what I would do.
You can try Linux Mint, Open Suse, Fedora, plus a whole list that Unetbootin will show.
I would go with 32 bit versions unless you have more than 4 gig of ram. I run 64 bit Ubuntu besides 32 bit AntiX and see no noticable difference other than how much ram can be enabled using a 64 bit distro. Speed difference is not noticeable at best. But you can try 64 bit. If it does not boot. Then start over with a 32 bit version. My Celeron 900hz Asus EEEPC 900 is 32bit so I am a bit surprised your 900hz emachine is 64 bit. My 64 bit machines are dual core Asus Micro Desktop and Dual Core IBM M57 Desktop. All my Boxes are Linux only systems though.
