Ramdisk is a virual disk in ram memory. If windows doesn't recognize memory controller asVincentCiancarelli mentioned it, OS doesn't see any memory (or doesn't see much of it) so it cannot install any ramdisk. My wild guess of course. But what I don't understand is why original win8 got installed without any problem from the dvd. They've changed the model of drivers?? Changes form 8 to 8.1 were suppposed to be minor and rather superficial. Somebody from Microsoft respond please. Tell us straight if nvidia chipset is going to be supported (and when) or tell us it's the matter of nvidia support. Then we'll know for sure there is no chance of getting 8.1 working through the windows store.
Thank you in advance for any relevant piece of information.
