My Mom recently bought an ASUS VivoBook X202E laptop. I have a USB (bootable) with Windows 8.1 on it, which I'm trying to install on her laptop. When I go into the BIOS of the laptop to change the boot order, so I can launch the USB, there is no other recognized devices besides the hard drive. When I try the USB on my own laptop, the BIOS recognizes the USB and I can use it properly. I haven't updated the BIOS on my Mom's laptop, but do you really think the BIOS needs to be updated if the laptop is < 2 years old?
