Windows 8 not installing using USB on SSD
I am in a predicament. I am trying to install Windows 8 on a ASUS M3A78-EMH desktop machine. I am using Windows 8 boot files on a USB, which has been correctly formatted etc. The Windows 8 file loads using the USB, it goes past the language installation and install. But when the next stage shows to select which HDD to select to install Windows 8 on, it displays blank. Then it comes with a message 'A required CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now.'
Help would be really appreciated. Thanks :D
