Do you wish to boot from a USB stick?
If so, press F2 upon booting.
Navigate to the 'boot' section
Find your USB device in the list, you are looking for USB hard disk or similar
Put it at the top of the list
Save, I believe with F4, then restart your PC

Similar to the above image.

Unfortunately - I can not find any option on the Samsung website that would allow you to upgrade the graphics card in this computer. It appears that the graphics are built onto the motherboard. This is pretty typical with a lot of laptops out there.
