hi this is just a quick hard drive up graved over Nancy's ex 401 a it's kind of the same process for the x5 o18 is just a couple more screws but everything else is the same it's just a slightly bigger model now things you're going to need is some kind of tiny look screwdrivers I've got this from the pound shop your hard drive and some in supply open I was like to use a guitar pick and some kind of light I've got a little LED lamp clipped on the desk here now there's two ways you can do the hard drive upgrade you can either just put the hard drive in blank and upload a disk drive with Windows 7 or 8 on it and when you set up or you can do a cloning now I've cloned my system this has already got windows installed on it ready to go from we turn it on anything to know is that when you close a drive you will need to reclaim the space back and your new drive if it's a bigger drive and that pa
