Hi, I installed an SSD to mine last weekend an boy does it make a difference. The original hard drive was an obvious bottleneck in the original setup and the entire computer is far snappier now. It was a little difficult to install win8 as I was trying to piece together the snippets of information I could find around the web. Get the back off the vivobook by unscrewing the 9 screws on the underside of the unit. The plastic backing will then require a little bit of a tug but the way it snaps on means there is little risk of breaking anything off during this process (so don't worry!!) The HDD then unscrews easily and you can replace it with your choice of SSD. *NB* the fitted hard drive is only 7mm high and the standard SSD size is 9mm so get a low profile version if you can. I had a Crucial SSD which did not fit - my solution was to simply strip the SSD down to the PCB and install it naked! OK- get the back back on and grab yourself a copy of Windows 8 RTM English, 64-bit (x64) and burn the iso to disk or...
